I respect you for acknowledging that!

I’m thinking about getting the f18 ,I’ve read and heard on sealed you have to crank the volume to get sealed to sound good?

@@jamesstandard3516 incorrect. For shitty sealed you have to crank it. These you don't. Yeah, you have to turn them up a little higher than a ported but you're getting a lot tighter bass from sealed

Lol so 2 of the f18s in a room 14x17 is going to rock the house when we watch a movie

@@jamesstandard3516 yuuuup. My house sounds like it's coming apart sometimes

I appreciate that!

Awesome dude, I'm happy for you!! The FVX12 remains my favorite and most used subwoofer.

ahahahaha, thank you dude! I wanted to check out the 15 but figured the 12" would be appealing to more people including myself :D

Hell yeah shawn, that's what this channel is all about. To help people make decisions and obsess less lol :D

oh yeah, love my F12 also, it play so damn clean!

hell yeah brother, glad you're enjoying them!!

I was just going to ask about this this speaker too, I thought he also revised these or it might have been your channel lol

Really? I've only heard the Bravus 8/10 models and found them to be killer for their size/looks in a theater setting but only just "okay" for music only. But I guess if you match them with speakers that use heavy drivers & voice coils then it would actually be a pretty decent match. They just couldn't keep up with lighter speakers like Focal.

@@NemoPropaganda Yeah, we think it's a great sub for Home Theater use absolutely - and although it's obviously not as fast as a sealed sub would be, for the specific genres/types of music we listen to, we thought it sounded really good!

Just checked out your video on the 12D, awesome. I used to own a pair of Speedwoofers so I found it helpful that the 12D was a step above for sound quality. I have a pair of V6T towers so I'd love to try out the 12D one day. If you get a chance to compare them to the REL HT-1205 I'd love to hear it.

It's true, this is one of the most hidden gem subwoofers out there. If you can accommodate the size I don't think there is anything better.

That is an excellent match! I have the Chora also, try setting it to 1p music & 24db slope at 60hz. You'll have to figure out gain/phase on your own though :D

oh yeah, 1 was plenty. Unless the room has a really wide seating arrangement 2 would just be for aesthetic balance.

@@NemoPropaganda really happy to hear it retains the high music quality and actually “adds” dynamics. Wow, impressed

If you have the skills I'd say go for it, otherwise a pair of FVX12 is $1803 with the 5% dual sub discount. 18" is just way too big for me, even as an end table that's a big end table lol.

@@NemoPropaganda I have a large open floor plan, so lots of air to pressurize to get the low notes, probably not the best for dedicated listening rooms. I'll be sure to build a mock up out of cardboard first to see, but it's 21x26x31? Smaller than most people would thing for an 18. I seen the same build where they built the 2 boxes into the sides of their TV stand and it looked amazing. I always wanted to go rythmik, but once I decided I wanted dual ported subs, the price made me think twice. I'm from Canada, so the shipping, exchange, duty adds a lot.

oh yeah, you got the big boy!!

I should have a T9x pair here in the next few weeks but t9x vs fvx12 has a huge difference in aesthetics and size that should be considered, I'm surprised you'd cross shop the two.

Wasn’t really cross shopping the two. I’ve had my sights on a Rel only for some time. But this review is making me wonder. I have the space for a big sub in a large basement room but don’t want anything sluggish or boomy. Recently sold a Hsu vtf-3 mk 4 that was nice but had to stopper both ports to be more enjoyable to my ears.

@@pkats9093 Ah, I see, how large is the basement?

@@NemoPropaganda 14’ x 36’ x 7’h. Lots of length for bass waves to propagate. Thick bass traps in the corners of the front wall. Rarely have any boom problems though. The consensus seems to be Rel is the quickest and most musical and the best match for my Maggie LRS.

@@pkats9093 Both have excellent SQ, one gives you more SPL & Extension, the other gives you superior aesthetics, fit & finish. Choose the one you feel an affinity for, you can't go wrong either way. I would call each company though and make sure whatever you're getting is large enough for that room as you have a good amount of volume to fill.

Bro I want one but they're too expensive, JL would have to send me a review sample.

excellent choice!!!!!!!!!!!!!!

I already reviewed the F12SE so I don't think I would also review the G model. Rythmik mid bass is among the best in the industry already but I think Rythmik themselves could probably tell you more on how it's different.

Rythmik makes the finest ported subwoofer I have ever heard. I continue to use mine daily in a music only system for whatever thats worth. That's how darn accurate it is. Arendal is also a fantastic option though I have not heard their ported subwoofers, only sealed and I consider them an excellent alternative for regions where Rythmik is not available or for situations where you need a narrower front baffle.

excellent choice! This is still one of my favorite subwoofers and still gets my highest recommendation. I believe this is one of the best vented subwoofers money can buy.

@@NemoPropaganda How does the SVS pb-2000 pro compare to this sub. I see they are the same price

​@@DiscoDub74 PB2000 Pro is very good but cannot match the FVX12 in any metric. FVX12 stands apart and is possibly the best vented subwoofer.

I wish I could have them all too but I gotta send them back :(

eh, speakers companies aren't that great at making subwoofers, a few can do it but the rest seem to be a poor value proposition. Like B&W makes a fantastic subwoofer but god damn $1500 and only 250w 10". I'm sure you'd rather have a REL T9x or Rythmik F12SE at that price no?

@@NemoPropaganda Good point on the the value proposition. I already own a Rel T9 but it's been dead since 2018 and I paid like $1.5K back around 2011. So I am no longer interested in the Rel's due to short life span. However, the Rythmik seems to be the best of both worlds (H.T & Music). Am looking forward to your review of the RSL speedwoofer :)

@@Audioloon have you reached out to them to see if they'll send you a new plate amplifier? Speedwoofer is good but it's no REL/Rythmik competitor, not even close. There is a big price disparity. Under $500 the speedwoofer is amazing but the $589 Rythmik L12 would take an easy win.

@@NemoPropaganda No, I did not reach out to Rel as it was out of warranty when it croaked. Never dawned on me to reach out to them anyway. Will give it a shot. Thanks for the heads up on the RSL. Appreciate what you do for us! Thank you.

@@Audioloon of course my dude! Even if you have to buy the plate amp, maybe some haggling will get you a deal on it :).

The sealed one is great too!

Thanks Sean, yeah I've heard a few other guys mention that down firing subs weren't a good fit for their room. Down firing in my room sounds just as good as front firing so I guess I'm lucky. I've had the T5X, 9X, and now the 7X and while the 7x is a nice upgrade over the 5x I didn't have any issues with the down firing design but if someone can afford the 7x over 5 it's a worthy upgrade for sure! Thank you for the music recommendation, I'll check it out :).

@@NemoPropaganda absolutely! Enjoy! After you're done with Sasha and if you like it, try Trentemoller, The Last Resort album as it's another good one. Take care!

I'm sure it is albeit with a +$450 freight charge plus import taxes. Based on my experience shipping abroad (as I have clients in NZ) I'm guessing you'll have a landed cost under $2300nzd. I'd reach out to Rythmik to see if they can get you a quote, it shouldn't cost more than $500 in freight alone.

But it would be much cheaper (with respect to freight) to buy one of their sealed models like F12SE as the box is so much smaller shipping will be much less.

The shorter F12SE might look better better visually since the heresey iv are short but either is a stellar option that should satisfy exactly what you're looking for.

@@NemoPropaganda Yes, agree, but they were out when I looked. With that being said, I really do like very low bass as long as it is very well controlled and natural sounding as you mentioned in your review. So, I'm going with sound over looks. Again, thanks!

ahaha did I say both? As long as the subwoofer doesn't get upset with me for assuming it's gender I don't mind lol.

ooo congrats!! have you received it yet? The only sad part is I've reviewed about all the ones that are reasonably sized so there are no more Rythmik subs left for me to review :( I suppose I could check out the sealed 15 at some point...

Yea. Nemo is the reason why they are out of stock in most models. I'm debating between an E22 and E15HP2.

@@Venezuela305 2 12" driver has the same surface area of a single 17" driver so you will get more moving mass and double the motor force with the E22 along with a better voice coil to cone area ratio but the servo tech kind of makes it hard to interpret how much of a difference any of that will really make. I would decide based on the dimensions and visual aesthetic since they cost & weigh the same and based on my experience with Rythmik so far they are all excellent. One thing the E22 should have more of is sense of scale but I'm totally just guessing here based on my L12 vs L22 experience.

@@NemoPropaganda I asked Brian at Rythmik a similar question, and he said: "...E22 is faster and F15HP is more authoritative..." This response threw me off. Even their site claims the E22 has more output than the F15HP. I wonder if it has to do with the power difference. Their claims leans towards E15HP2, but my gut says E22. I absolutely loved the REL 1205. I tested it for 30 days. I never got closed to maxing it. If only would dig a little lower it would be perfect., hence de idea of E22 was born.

@@Venezuela305 I could see that actually, not to get too complicated but the 15" driver likely has a lower Fs (resonant frequency) so at the lowest octaves it could have an easier time reproducing something like 18hz so it would sound more authoritative and effortless in that region despite being 1db quieter than the E22. I think this is a situation where the two products will perform nearly identically to each other which is why I think it's best to make the purchasing decision more so on aesthetics, shape, etc... All rythmik subs have crazy low extension so I think you'll be super happy either way.

indeed, I still have it and I still love it!

@@NemoPropaganda I gotta get one two

Niiiiiice!!! It's still one of my favorite subs, I still have my review sample here (I asked Rythmik if I can hold onto it longer) but when they do end up asking for it back I might buy myself a white one.

No good deed goes unpunished right? 😅

The REL HT1205 subs are great for sealed 12" but they're more of an sb2000 competitor. If you can fit the larger FVX12 you surely will not regret it.

@@NemoPropaganda actually we talked before before you got your F12's, I was encouraging you to get a pair... because I had a pair and always thought they were great. I have/had a James Sub, a SVS PB13 Ultra, a REL S/812, a pair of Rythemik F12's and now a pair of Rythemik G22S's. I still have the James Sub in the tv room with a small Kin mini 5.1 surround system. But for my main stereo/home theatre system I now have the pair of Rythemik G22's. (Think 2 dual opposing F12's) For the large space they are in and they are ridiculously great for stereo and great for articulated bass for movies. Saying that I kept my single SVS 13 PBUltra for the theatre experience (body pounding bass addition), but the pair of Rythmik G22's as well crossed over properly with my front left and right Focal Sopra 3's and placed in dual mode for LFE movie watching. My F12s were fantastic but a little shy of filling up the room, and my single REL s812 was fantastic but holy underpowered for the room. To be fair the Rythmik's place the much hyped REL into second place. The REL was more dynamic but it failed to integrate as well but was just as tonally accurate. (In my opinion as good as it is it costs too much for its performance... My wallet was bigger than my research that day) The Rythemik G22's are a huge step up for music from the F12'S and the REL S812... those dual opposing drivers are incredible.

@@mesonto Oh man I'm jealous! The G22 look awesome, they're just too heavy for me to play with and might be too much for my room. I stopped using the F12 pair as 2 in my small room was overkill so each sub was barely running off maybe a few watts and not really hitting it's stride. Switching to just 1 and making it work a little harder sounded way better. I think my room is best for 2 small subs or 1 bigger one but I can't have 2 12" subs in here, they just wont hit their sweet spot.

No I don't like PEQ and PEQ should only be used if your room has major issues. Luckily my room does not have any major issues :).

Rythmik ported subwoofers have sound quality that rivals and often beats most brands sealed models. FVX12 is one of my most used and loved subwoofers, my only complaint is it's not small and cute looking lol

Thanks for the reply, I’m almost certain that the fvx-12 will be my next sub upgrade maybe two depending on how open or big my next house is. I also have Polk r200s thanks to your review and others, they are amazing for the money and I almost went for the focal aria 906 but the price of the polks won.

@@roelcorral7720 Nice dude! I still have my R100, I can't bring myself to sell them even though I don't need them lol. They just sound so good for the money. I love them.

Hey brother, oh man, that is a really difficult question to answer because aesthetics is so important to me. My favorites right now are the REL T5X pair, Rythmik F12SE or FVX12, and the KEF KC62. I have a pair of REL T9x coming, maybe those would be my "perfect" subwoofers :D

Hey Phillip, "suffice" is very personal my friend. But here is the simple answer. Yes the F12 will not have any problems in a 1600 sqft room. The FVX12 on the other hand has bass more like a sealed 15". If you can fit the FVX12 I think you will be extremely happy with it but if room aesthetics are very important to you the F12 is also very capable. Basically the FVX12 will have more of that theater rumble than any sealed 12" but the F12 also rumbles, just not as much as the FVX.

omg bro, that's going to be a massive upgrade for you!!!! I'm so happy to hear this, you're going to be very surprised :D

@@NemoPropaganda do you know how long it usually takes for them to deliver ? 1-2 weeks ? Do they make them when the order is placed or done they ship existing stock ?

@@NemoPropaganda absolutely will do! I’m in Texas too so that should be a stone throw for them

Rythmik will make a passive radiator sub the same day REL adds a DSP to their subwoofers which would be never. For Rythmik to do a passive radiator the cabinet would still be large as it would only shrink by the amount of volume the port takes up if you expect it to have the same extension. But I'm also guessing it may not pair well with their servo tech and could potentially undo all the goodness the servo brings to the table.

my opinion is that they are inferior to rythmik but represent a fair value for the money.

No it does not, it uses a 400w Hypex based servo amplifier. I suggest you reach out to Rythmik to see if they have other options. Sometimes they are able to offer an alternative if you email them.

My review is based on using all settings. Shane has an extremely challenging room so he has to set his to low to get the most rumble. Changing damping to medium or high will have the F18 play tighter and faster than most subs on the market so I would not worry about that so much. There is a user in my discord that also has a pair of F18 if you want to ask him his experience. Our discord is free and links are in all the newer videos.

The 1205 V1 is fantastic but I think its important to remember it launched at $699. It's a great performer and I still love mine but it cannot compete with the E15 or FVX12 both of which are much larger and more expensive.

Since the bulk of my reviews are subwoofers for 2ch stereo I do not test maximum output. Generally speaking most subwoofers have more than enough output for music systems, especially larger vented models. As far as comparisons it's really simple, there is no other vented subwoofer that exists anywhere close the FVX12 in terms of price that has the sound quality & fidelity it has. The FVX12 stands apart, it's on it's own island, it has no competitor.

great choice! the f12 extends very low and sounds fantastic!

I think Rythmik makes the best sounding ported subwoofers in the world.

Hey Scott, depends on which 2 smaller subs you're considering.

Hi Brian, I love REL and Rythmik but just to be clear I have not heard the S812 specifically but if you like the REL sound but want more output for your money Rythmik is the logical place to look or REL's own Predator 1510. Vented subs generally have twice the output of their sealed counterparts so yes you should gain a good amount of headroom by going from dual sealed to dual vented subs and since the vented subs you're considering are Rythmiks you can also expect to have very good extension & transient response also! Now if you're trying to play the intro of Edge of Tomorrow at 110dB without bottoming out you may want to consider something larger like their F18. Another way to look at the FVX12 is (and again this is generally speaking) a vented 12" has similar output to a sealed 15" so you're going in the right direction for sure.

do it! this is still one of my personal favorites!

@@NemoPropaganda thanks yes can’t wait tried the sb3000 didn’t like it at all sold it rythmik has always been good

Ordering mine tomorrow can’t wait to get it

@@danemoreno88 excellent choice! You going for the gloss black or one of the vinyl finishes?

@@NemoPropaganda I’m getting the black oak vinyl version hopefully it matches well enough with the ebony klipsch

Hey Daniel, so I would definitely ask Rythmik their opinion on that but my opinion is this: It's good that size doesn't matter for you but at the same time contrary to the common saying of bigger is better, having too much headroom (big powerful sub) and not using it is not good either because the operation point will be below the optimal linear range. It's almost like having a Ferrari and not going over 3500rpm, the valves will get dirty because the car needs to be driven hard, (to a point). Now if your room is larger and you're looking to create a reference theater experience the FVX15 may certainly be for you. Rythmik will be able to answer that question better than I can though :).

@@NemoPropaganda I really appreciate your input and I'll definitely reach out to Rythmik as well. I'm looking at it primarily for a 2 channel music set-up and it will be in a small room now but it would be nice to have some flexibility to move it to bigger room down the road. Any thoughts specifically about the F15HP vs FVX12? What kind of tradeoffs should I expect with a smaller driver and less power but being ported? Thanks again for your help, I'm amazed at how willing you are to reply to so many comments.

@@danielvogel7322 I havn't heard the F15 so I'd rather not guess and instead suggest asking Rythmik directly, they're really best qualified to answer that question. Anytime you're between two products made by the same brand I think it's best to ask the company directly. Us reviewers are better at helping people decide between different brands.

@@NemoPropaganda Fair enough, thanks for taking the time to reply.

I have not heard it but I'm sure it's impressive.

I own dual F18s. Incredible subs. I had SVS SB13s before the 18s and the 18s are better. Highly recommend!

@@chadhunter8757 I hope so Chad, an 18" driver has 92% more surface area than a 13" 😁 You would essentially need 4 13" subs to equal 2 18" subs.

brother we both know that would be awesome, absolutely do that!

Both sound excellent, midbass is better on the FVX12 at any volume. Low end extension at very low volumes was very similar but the larger FVX12 had a sense of scale the tiny KC62 just can't match, even at lower volumes.

Thank you for the feedback but I just do this for fun :). This review channel is my hobby, not a business but I did start showing more angles in the most recent Emotiva RS11 video, you might find that more to your liking.

@@NemoPropaganda Take measurements for fun hahahah

@@navinsamuel2005 that doesn't sound like fun to me 🤦‍♂️

I would later go on to crown this subwoofer of the year for 2021 and it remains in my arsenal as one of my favorite and most used. The SB3000 is a well made compact subwoofer if space is a concern however it cannot compete on any level against the FVX12. The FVX12 is better at any discriptor of sound or bass you wish to use. Transient response, note to note distinction, integration, handeling of delicate passages, etc... music or movies it doesn't even matter, it's the champion.

@@NemoPropagandait sounds great! Definitely went to # 1 in the subs I'm considering

unfortunately they're a bit too large for my room, exotic designs like folded horn, infinite baffle, etc... have their pro's and cons, they can sound really good at one aspect at the cost of another.

easily class leading. I have yet to find a vented subwoofer that sounds better and of course it has the output and extension also. This is the biggest hidden gem I have found in all of my hifi journey.

I have an RSL Speedwoofer here and it's fantastic at its $400 asking price and possibly the best subwoofer under $500 but it can't even come close to the Rythmik. If the Rythmik FVX12 is too big how about the F12-400? I have one of those here too (well F12SE version) and it's very close the FVX12, just sealed version essentially. It has an identical sound signature just less authority at its lowest extension but still loads more than the Speedwoofer.

@@NemoPropaganda Yes that might be it! About the same size as the RSL and with a 12" wow. So does the SE have a different amp than the 400? Thanks!

it depends how extreme your taste for bass is, maybe you will only be satisfied with dual 18's maybe a compact sub is enough for your taste, it's really hard to guess unfortunately but for most people a single FVX12 will be plenty!

I'll put it like this my bro. I genuinely believe Rythmik makes the best ported subwoofer in the world and comparing it to a Monolith is like asking how a Porsche 911 compares to a Ford Mustang. There's nothing wrong with a Ford Mustang, in fact it's a great car, but it's not a 911, and it never will be.

I have not heard the 15" but Rythmik themselves should be able to answer that question very easily :).

Looking at the output comparisons, the sealed 15 outputs just a hint higher than ported 12. So that's $450 more for sealed. I cant decide. I wonder how much of pain it is the return these subs if one decides to go bigger or ported...

@@samray3461 Rythmik ported subs play just as clean and quick as sealed subs so unless you're looking for a certain shape or want sealed for it's smaller cabinet I'd say just save the money and grab the FVX12.

I have not heard the PB-2000 but I did own the PC2000 for a bit and I prefer the FVX12 however for customers outside of the US where Rythmik is not available the SVS 2000 series is a fantastic option with a lot of output.

@@NemoPropaganda thanks so much for the reply - love your channel its my go-to for purchasing decisions!!

@@idkisaidit thank you dude! I appreciate that!

Hey Curry, the 12" should have better transients but the question is can you hear it or not? And I'd say the same about 2hz, sure it's a difference but can you hear it? The 12" is seriously capable, unless your room is very large or you want to recreate a real reference theater the 12" should be more than plenty.

I haven't heard the monolith 12 but it's a PB2000 ripoff, the FVX12 would most likely be better than the monolith in every category. I kind of view monoprice the same way I view Hyundai but at least Hyundai isn't copying anyone else...

@@NemoPropaganda Really? Wow I have heard nothing but glowing reviews about monoprice subs. From AVS forums to even right here on youtube comparing head-to-head to svs.

​@@Professor5180 most people don't have as many data points with respect to music as I do. This channel is for 2 ch music application. Most people singing high praise to the monolith are doing so with respect to its home theater performance. I'm not a HT guy, I'm a 2ch music guy and there is a huge difference in what I need from a subwoofer in a 2ch music system that 95% of large box ported subs simply can't do. Large box ported subs generally sacrifice everything to accomplish maximum low frequency extension and SPL as is required for HT. The FVX12 is an exception here, it's servo tech stops the trade off from happening and instead you get the best of both worlds. HT subs are like drag cars, they're 1 trick ponies while music subwoofers are more road race cars, they're still fast and can tear up a drag strip but they can do everything else the race track demands besides simply going straight as fast as possible.

​@@chrisrichardson958 For theater or music? I have not heard the Predator 1508 yet but a good ported 12" generally has the output of a good sealed 15" so if you're between dual FVX12 or a single Predator the dual FVX12 is an easy choice to make here.

@@NemoPropaganda Thanks for getting back to me! Sorry yes it’s mostly for theater. I do love ported subwoofers but idk the rel just seems so fast and articulate but 2 is definitely better than one

@@chrisrichardson958 FVX12 is also extremely fast and articulate, in fact it's midbass is better than the HT-1205 I reviewed and is more on par with REL's TX range. You said it yourself, you like ported subwoofers. This is the best one i've ever heard, buy a pair and don't look back, you won't regret it.

Hi, I made a video for that, enjoy: kzfaq.info/get/bejne/qKuqY5aJ0MnXnH0.html

Is that a real question?😅🤣 Rythmik all day every day for music and home theater 🔥❤🔥❤

Hey Shankar, FVX12 for sure bro!!! The FVX12 has roughly double the output of it's sealed counterpart which is really important for theater and it' still killer for music. If you want chair shaking bass you might need a pair or something bigger than a 12" though :). With that said in my 2021 year end video I ranked the FVX12 as subwoofer of the year and I still stand behind that, it is the finest ported 12" subwoofer I have ever heard and I do not believe a better one exists at this price point nor do I know of a more expensive one that is better. Essentially the FVX12 gets my highest recommendation.

@@NemoPropaganda Thank you very much for your speedy reply. I really appreciate it. Your reviews are really great and helpful. I 've subscribed for your channel. Thanks again.

@@NemoPropaganda I suppose even dual L12s can't match a single FVX12. Am I right. Also , the Amp on F12 are different from the Amp on FVX12. Will that make a difference in th SQ??

​@@shanxac FVX12 uses the highly regarded Hypex ampifiers, you're welcome to read up on them yourself, personally I don't care about the tech, I only care how it sounds, it could be powered by goldfish, if it sounds good I'm happy, and FVX sounds absolutely fantastic :)

@@NemoPropaganda ""it could be powered by ...."" 😀😀. Very well said. I agree with you. Well, you've made my decision making a lot easy. Guess I'll pull the trigger on FVX12 then. Thanks Nemo. I'll pen my thoughts on it post-purchase. Peace.

I have not heard the PB3000 but vs SB-3000 there is a big size difference to consider but the FVX12 is more effortless with it's bass, has more authority down low, and much better midbass. The SB3000 is amazing and has crazy output and attack for it's size.

i have had pair of sb3000 and they are loud and have huge attack but everything sounds the same, totally lack of sq and definition. Totally do not recommend svs.

Hey Tyler, yes absolutely. I would choose the single FVX12 in a heartbeat.

@@NemoPropaganda haha, I am still stewing over this subwoofer. Only because I have limited space. I can only swing 15 inch wide cabinets, OR I put my bookshelf speakers on top of the subs, either on short stands or actually resting on the sub cabinet. You think it is a bad thing or a faux pas to have bookshelf speakers resting on top of a subwoofer? If it is better to have bookshelf speakers on seperate stands, I can always get 2 Emotiva RS11, which I have had a very close eye on as well. Thanks in advance for any feedback you can offer.

@@tycheesey that would look too weird, I wouldn't do that. I'd get the F12 instead, that's 15.75" wide if that fits? Otherwise the Emotiva RS11 is pretty damn good!

@@NemoPropagandahey thanks! I literally have millimeters to spare with two RSL speedwoofers, which are exactly 15 inches wide. I read that the Emotiva RS11 are exactly 15 wide as well. I could fit one fvx12 with the audio rack off center, but my rack, subs and speakers all fit exactly into a nook that insets from a long stretch of wall.

@@tycheesey it sounds like you prefer to keep the aesthetics which I totally understand. A pair of RS11 is a badass option for sure! Here you can see the size differences, kzfaq.info/get/bejne/d9KFfbSg15zYfWQ.html

I have not heard monolith but I have a hard time imagining any brands ported subwoofer being better than this one with respect to sound quality and extension for this size and price.

@@NemoPropaganda I was stuck between these and the V2 12 THX Monoliths to replace my Klipsch Rp112. But after watching you and Zeos Pantera I feel these will be the best for my money. I have dual Klipsch rp112 for the moment and they just can't move the air and can't handle my Marantz sr8012.

@@shorty332 FV12 can bring the pain, you won't be disappointed :)

That's a great question and Rythmik can probably explain more but wattage is only 1 factor. My understanding is the old Velodyne servo models were very inefficient so required more power and it's important to remember they were also very expensive. Rythmik subwoofers are very efficient so your power goes a lot further. I would not worry about the wattage, even the 300w L12 had plenty of power and played plenty loud!

@@NemoPropaganda Awesome, great to hear! 👍 I feel I am leaning towards a F12 beacuase I am very curious in the servo technique. But I just have to evaluate if I should continue using my BK subs. Thanks for the reply!

@@sebulbathx unless you like to feel the weight of the bass (like heavyness) you will enjoy the Rythmik a lot. Though I'm not familiar with BK.

@@NemoPropaganda Yeah that is what I feel I am missing with my subs at the moment. They sound really great and integrate very well especially for music but the physical feel is really missing. They go on paper down to 20hz but I guess the output isn't there. And size-wise the F12 seems to be what I want. Besides the more expensive alternatives like Velodyne but Rhytmik seems to be what I am looking for. I guess SVS would be a great choice but I wanna go a little more different route because everyone wants or have an SVS as it seems. Also I am with you as you said in the video if it works well with music it works well with movies. 👍

@@NemoPropaganda BK sub are very similar to Rel like simple construction but very well made and nice finishes and no nonsense approach. www.bkelec.com/HiFi/Sub_Woofers/XXLS400.htm

At some point physics is just going to be a factor, even the larger REL's aren't as speedy as their smaller counterparts but it begs the question what is "fast enough". Rythmik will know their own subwoofers better but I would imagine the G22, E22, or pair of F12 may have a quicker response than something like the E15HP. But the E15HP is probably still a very quick subwoofer compared to other 15" models. I am thinking about reviewing one of their 15" subs but the weight is kind of a problem for me. It might be best you just ring rythmik and have a chat with them and see what they recommend.

@@NemoPropaganda I guess when I prioritize, SPL is not really as important as fast transients and overall SQ (might push me toward the 12's)...but I'll have to think about 1 vs 2 subs a bit. I'll give the Rythmik folks a call. There probably isn't a "bad" solution, perhaps ones that are slightly less optimal. They can probably help with those finer details. I hear you on weight. I might have considered some of the bigger Rythmik subs (dual 15s) until I looked at the weight. I can only imagine the fun in trying to find the "optimal" placement for a G25HP... :D

@@nmnate You are correct my bro, you're deciding between 2 very capable options :D. I'll say this, I'm pretty busy right now but after things cool down I will give some serious thought to reviewing the E15.

Nemo Propaganda Please do. E15HP2 if I could make a request. Looking forward to it.

Nemo Propaganda Ya “fast enough” is a good question. Also what kind of music you listen to matters a lot. Rock music may benefit from the slightly quicker transients, but for rap and pop maybe benefit from the more authoritative sound. I hear a lot of rap bass is pretty sloppy to begin with.

I actually filmed a review for it lol, I just have to edit it :D I almost got rid of her a few months back but decided to keep her.

@@NemoPropaganda Awesome. Love the colour on yours. I have a B8 S4 and have thought about getting a C7.5 S6 instead. Almost listed my S4 for sale but decided to keep it as well :)

@@Pawan2013 Thank you! That's a good choice, my buddy just got a B8 S4, it's much livelier to drive than my S7. The B8 is more a sports car while the S6/7 is more a grand tourer. I do miss the sporty dynamics some times but I wanted a big heavy car this time around :D

Yes, absolutely. Rythmik ported subs have better SQ than 99.99% of sealed subs and more extension than most vented subs of the same size. They are the definition of a hidden gem.

@@NemoPropaganda please post video for fvx15hp if possible

@@hometheatertamil9859 Hi bro, I can't review everything and I am already covering Rythmik A lot, I've done L12, L22, F12, FVX12, and soon will be doing E15HP2 and G22. Rythmik is like ferrari, you don't need to see a review brother, it's the best, just buy it :D

they're very different in overall size but based on your earlier comment of wanting a sub that could handle a larger room incase you move heres my 2 cents: the FVX12 is a vented sub, you'd need 2 1205 MK2's to compete with its output at all frequencies. These are both extremely high SQ subs so fidelity is not a concern on either. So you could either buy the larger FVX12 now and be set for a larger room or buy a single 1205 MK2 now and upgrade to dual 1205 MK2's later down the line if you move to a larger room. Either choice is a great one.

@@NemoPropaganda Thanks, will the fvx12 lose anything being in a smaller room?

@@tonydillinger2553 nope, it has a wide sweetspot so it should sound great no matter what unless the room has major issues.

if SQ is a top concern when buying a subwoofer Rythmik is the only option. Nobody else is making high SQ vented subs.

​@@NemoPropaganda Wouldn't Hsu Research also be a top contender for high quality SQ vented subs too?

@@oniiz8685 I honestly don't think anyone else makes an SQ vented sub besides Rythmik and I've never heard any of the guys in my discord that have owned them refer to Hsu as an SQ sub. There are only 2 SQ brands right now that I know of, Rythmik & REL, that's it. Some brands strike a really nice balance mixing attributes of both like the Arendal 1723 1S but that's a different story all together.

@@NemoPropaganda Oh I thought they struck a fine balance between SPL & SQ, they seem to be very highly regarded for their price/performance value but I understand Rythmik to be king overall ;) I was curious if you'd entertain the idea of reviewing Definitive Technology's Descend DN12 or DN15 subwoofers?

@@oniiz8685 I tried but they didn't respond to my inquiry and I don't want to buy them with my own money because I don't usually like PR subs too much.

you'd like this thing a lot bro!

@@NemoPropaganda it sounds like it! I'm pretty well sold. Even if I don't prefer it over my sb 3000's, I could put it in my living room system and move the Svs over to my other rig.

@@JosephTongret Do it!!!!!!! I know you've been eyeballing shit :D Youre in the USA right? 45 day in home trial :)

@@NemoPropaganda yeah, Ohio

@@JosephTongret well they're sold out for the next few weeks so you got some time to let it marinate :). If you were closer I'd say just come over and listen!

Nice dude, the only bonus I need is knowing my video helped you stop obsessing and moved you towards a decision you will be happy with.

@@NemoPropaganda For sure, your videos are very helpful for many to decide on the right sub.

Hahaha my guy helps out a lot of people he deserves that referral bonus.

you didn't like the vs KC62? 🤣

Lol it got weak very fast after 10:35 and the rel comparison. From watching a lot of reviews this sub is second in my line up after the rel subs I wasn’t surprise your reference to it with the t5xs Once a sub hit that reference mark of a t5i range there very few subs to compare it to that brakes in to that level and price range

@@haydenbarrow9603 daaaaamn bro, weak? come on lol, cut me some damn slack brother 😂 In all seriousness you are correct. REL's T5 is my SQ benchmark.

Hey your review and response was on point till 10;35.. sq and op at the price the bench mark set by rel dual t5i and x AND now the one fvx12. When I said it got weak after 10;35 it I didn’t meant you but what the fuck else could you bring up to this price bench Mark set The competition got weak
