If I would be looking for upgrading subs and have $2500 budget, I will go dual Monolith instead of the 1 SVS. It would be a smarter option with dual.

Been saving money for nearly 2 years for dual svs 3000 PB. I am finally going to be able to pick them up and add them to the theater. Thus will be a huge upgrade for me. Taking i been running mtx old school subs. I love your videos.

great video! both of those subs track extremely well in your room. the svs sub looks to be benefitting from a subsonic filter (a high pass filter) at ~18Hz. the monolith sub could greatly benefit from a subsonic filter also to keep its excursion in check when it starts playing below its port tuning frequency. ultimately, i think the svs will still play 1-2 dB louder than the monolith, but if the monolith had a subsonic filter applied it may have played the +3 dB sweep without signs of compression. dang good performance for over a grand less!

In ‘00, I purchased two Velodyne FSR-15s. They complement my SRS-SDA 1.2tls. The Polk’s and Velodyne is still perform beautifully; however, my ol’ lady hates the “big, ugly box.” Next week, SVS is shipping me two PC-4000s. She said, “the cylinder looks like a work of art.” Win-win for both of us. God bless

Congratulations on the excellent comparison, I enjoyed it very much. They are two excellent subwoofers.Despite the results, it's a hard choice, youthman, at least for me.

Rumor has it that youthman had to have a structural engineer come and inspect the building after that test.

I would really like to see your reaction to some of the popular DIY sub setups. Like the Dayton 18s in a full marty. Or alternatively seeing your reaction to some of the JTR subs. They are really in another class.

Thank you for taking the time to compare these so thoroughly.

Thanks for the vid bro bro. I purchased the monolith before there was a single vid out about them. My audio buddy talked me into it I was and still am blown away by these! I purchased a second one within 30 days after the first lol amazing as duels. You won’t be disappointed guys especially at that price point. Good luck all

Glad to see this channel growing! Can't wait to see you haul in and unbox that S7201...

First off thank you for this wonderful comparison between the 2 excellent subs. I have always loved the fit and finish of the svs with the app it's a hands down winner in my book but for the money and great price of $1300 dollars you just cant go wrong if you are in the market and have that budget for the monolith 15. They both sounded great, so thank you again for the comparison and you and the family be blessed. Take care friend.😊

Would love to see the test repeated, this time limiting the test signal to 20 Hz and above, or 30 Hz as above, as both systems may be using some sort of electronic filtering to control excursion at very low frequencies at higher signal levels. Also, what REW distortion graphs at levels where you notice compression in the passband may be of interest.

Thanks for the video just started it. Also thank you for not having any cringe “jump” or “intro” terrible sound clip like some others.

Youthman I played the shootout again with the SVS PB16 Ultra and the PSA s3611. Although in my room the PB16 rattled the walls more it's hard to forget the deep extended bass of s3611. I was actually playing it the first time in the living room with a Samsung soundbar and its wireless sub. I can see why I liked it better. The soundbar does not go low so the best qualities of the SVS PB-16 was more impressive. When I replayed it in my home theater room that is very similar in size to yours I see what all you guys are saying. I went ahead and bought the PSA s3611.The PSA sub wIll fit better in my regular theater room because the PB-16 requires more depth which I do not have. The PSA requires more width which I do have. As many have already reported you do a really good job without any biased that's really fresh. My background has always been High-End audio Pass Labs, Acoustats, Infinity, Spatial Audio, stacked Advents and others. I finally decided to go home theater to see if it would have any kind of chance aganist a true high quality 2 channel system. I run my church sound system and what I can tell you is most high end systems have far more details than what you hear in a live environment and until you get into the $60.000 systems the dynamic range of even one trombone cannot be produced with actual realism. My nephew plays trombone and he walked into the room one day and hit one note and that's when I realized what I was missing. Weight,full body and effortless. I still like the two channel systems but I'm having far more fun with my Dolby Atmos system 7.1.6. Your review on the Dolby Atmos Klipsch speakers was very accurate but I might add if you put the drivers very slightly above your ears you can sit right next to those speakers and not hear their location at all provided you have proper flat ceiling and height requirements. You guys not interested in not putting holes in your ceiling should read the Dolby Laboratories white paper on the Dolby enhance reflective speakers. Dolby feels that in certain situations they create a better canopy than putting speakers in the ceilings because if the ceilings aren't high enough the localization becomes more obvious. This is what I found in my particular room. The other thing I wanted to say is the dynamic range of my home theater system is significantly greater than what I ever had in a 2-channel system even when using excellent twin powered 10" subs. I feel there's also more enjoyment because more people can be involved in a home theater system (3 to 5 people get a sweet sitting spot vs one or two) and it does not favor a particular type of music or presentation. Youthman you make it fun too. You also have a great enthusiasm. I was trying to learn how to perform Roon Calibration and others on KZfaq tried to make it sound like brain surgery. You provided clear explanation for exactly how to test subs / compression test. I really enjoy the shrapnel hitting me from the boat explosion more so than hearing the height reflection differences between a 50' and 52' cathedral ceiling. I also took notice of that little smile you had on your face when you said will I be upgrading my subwoofers and you said well not right now but definitely. My wife watches the Channel with me she said all you guys are alike. I just want to know when it ends. I told her honey it doesn't end it just keeps getting better. Youthman again I just want to thank you for your efforts.

Great Job Youthman! I think you accurately described both subs very well. I have never heard either of them before but by going by specs, price, features and your REW results its easy to see where the cards fell. The Ultra 16 is the better subwoofer but at almost twice the price it should be. The Monolith, with all the the testing you have done with it, seems to be the absolute better bang for the buck performance wise. Loose comparison would be an Audi to a Camaro. The Camaro with give you that performance on a budget, but the Audi will give you the performance plus all the refinement with the price tag

What's up Youthman? Great video! Just wanna give you a heads up I don't know if you seen godzilla yet but damm the bass in that movie was insane even with my little pb1000 subs. My room was shaking. Also the atmos track was really good. So if you haven't checked it out you would be very happy with the audio. I know you live in Florida so your family and you please stay safe!

Great shot out Youthman! You said a great point. It doesn't matter what others think. In the end it's our own individual taste! Keep up the great work! Berlin signing off!!!

I saw you as a guest on audioholics thought I'd watch some of your videos really like this. Nothing better than watching a sub to work!

Good review 👍🏿 The Monolith Hits really low 👇🏿 I could hear the room shake before the sound came in 📳 For the price I'd go for two monolith 15's for twice the performance 💪🏿💪🏿

My conclusion is that I'd for sure rather have dual Monoliths and get output to 10Hz. If you put a HP filter at 16Hz on the Monolith you could probably get almost as high output for the Monolith. There is always a trade off between output and how deep you want to go. Test plugging some ports on the SVS16 and you'd get to 10Hz as well and see how the output compares then.

for 1500 you'd recommend the monolith over a PSA?

You should demo the SVS PB-2000... I would like to see it with REW Calibration. Demo 2 PB-2000’s vs 1 PB-3000.

Great comparison, I have to agree with you on being happy with what you hear. Will there be better sounding subs ? Of course there will be. But if it feels and sounds great, I would use the bucks to upgrade in other equipment. But that’s just me.

I would love to see a test between SVS and Paradigm. I have two paradigm x12's in back and 1 Klipsch 150sw" in front... Omg, the bass is insane in my theater room.

HSU should also be in your shoot out. Will give an SVS a run for its money.

Great comparison video Youthman! Both of those subs are awesome. Thanks for using those graphs again. I think I take away more from the videos with graphs. Thanks for all the effort!

HI Youthman! First time I write to you. Recently subscribed, from Mexico. I love your comparisons and style, you look like a really nice guy, and I envy you a little bit because your really nice setup. Currently I have a monolith 10" subwoofer and a speeewoofer 10. I hope someday I will upgrade to dual 12 or 13 inch subs. Kepp the great job!

That down to 10Hz is sexy with the Monolith. Too bad a lot of soundtracks are neutered for that ultra low frequency bass. That is what the bass EQ thread (BEQ) is for on AVS haha

Either choice, you have a great sub. These are the good old days of audio!

Great comparison. Have been considering an SVS sub for a while, but good to learn about some of its competitors, and the lower price seems easier to work with too.

Thanks Youthman I really enjoyed this comparison. Very informative. I am currently looking to upgrade both of my subs. For the price and performance I am going with 2 Monolith subs. Thanks again.

@Youthman when it comes to huge brawny crazy subwoofers, you´re the man! Unfortunately Monolith subs can not be had overseas (Norway)

would love for you to review the HSU subs with REW and compare !!! VTF-15H MK2

Amazing. The pb16 is now $2,900 up from $2,500 side you made this video. Meanwhile the new monolith 16 is $1,699 on a deep sale that will best it lmao

Tekton makes a 6 x 10 Subwoofer for around $1,500. Yep, 6 - 10" subs ran in series, stacked to about 6 foot tall enclosure. I've also been checking out Rhythmic Subwoofers, and they seem to be some really good subs, from a company that only makes subwoofers (like REL). They even offer DIY kits to ave ya a few bucks. It would be interesting to see a review of the Tekton 6 x 10, and also a TRhythmic sub. They are pretty high end subs, entry level around $1000. But have patented tech and operate like the RSK Speedwoofer. Which is probably the best sub for the price right now. Their 12' sub has some serious SPL.

Flex some of those subs on the song Lost by Phelian, the bass comes in and swells then drops in frequency and swells and drops again and swells then reverses Very satisfying and house shaking!

That was a really great video Michael. I learned a bit about REW. I'm interested to look into doing that technique in the future when I get to doing more tests on my own equipment. That was a great comparison. I think you pay more for the fit/finish of the SVS, which is outstanding. If people are really after a superior look, SVS is it. But if there's greater focus on performance, I'm thinking 2 of the monoliths would really do well to level out the sound and match the output of the SVS. Just my .02 😎

The Monolith measured smoother into the infrasonic region.

Ever since you review 4:01 ed them monoliths i rushed out and got 2 i love them when i move home i will get more if i need them. They never get even warm at the end of film.

Thanks for the awesome videos! In your opinion, if you had to choose between 2 Monolith 15 vs 2 SVS PB 16 Ultras based on home theater performance for movies, which would you go with? I’m interested in both but what I really care about is that nice deep bass that you can hear and feel and was wondering if one produced that better than the other or were they equal in terms of performance. Thanks again!!!

Def a fair comparative review considering how you highlighted the price difference between the two.

I have heard both and personally and owning svs and also velodyne, I would go with the svs.

When running the frequency sweeps it sounds like the house is going to collapse. LOL.

Good video. Not a fair comparison though, as you stated. PB16 vs JTR Captivator 2400 would be more fair of a comparison. That is if you have them both hanging around, and if you do your lucky!

Let's get ready tooo rumble!!!!!!

Good review since these are two subs I’ve been considering and have been curious about their sound. Any thoughts on reviewing Rythmic subs, like a G25HP, FV15HP or the F18? Thanks

Very informative... The Monolith is a great subwoofer at it's price point. I'd save the data to compare other subwoofers. I'd like to see how the JTR subwoofer compares... But as usual, great content.

Thank you for doing this review!

Very good comparison Youthman as always well done. As the monoliths is $1300 you could put two in your room and you’ve always been an advocate to subs are better than one no doubt the PB16 ultra is an amazing sub I have a room of approximately 2500 Square feet 2 PB 16s I think would blow the walls out.

Very cool. Wish I could see someone compare the PB16 vs the HSU VTF-15 MK2. Heck, you could do two VTF-15's for just a little more than the Monolith. Of course, may be a reason nobody compares them...I never see much excursion from my VTF-15, it sounds really good to me but doesn't ever really knock me over. However I did get hollow headed after tuning it playing the waterfall scene from Prometheus repeatedly. I think two of them would be ideal for my room-really it's one end of an open floor plan ~15'x35'.

Deep and nice bass which is better

Thanks for spending the time in these videos! Sounds like for the money your just better off with 2 Monoliths for the price of one PB16.

great video !!! Two solid performers!!

Hey Youthman, awesome review here I feel you were honest and backed it up with reliable measurable data. But did you try running the PB16-Ultra in extended mode? I could be wrong but don't they claim supported more output at lower frequency if you plug 1 of the ports, making it "extended". I could be wrong on this but wanna hear what you think about it. Anyways, thanks!

Cabinet shaking would drive me crazy and I would have to find each rattle lmao

Thank you!!!!!! Couldn't wait for this comparison!

Just like I was expecting! Great showdown! I hope that one day you could test PSA S7201.... 110dB at 18Hz! Unleash the beast🔥🎵

Have you ever used a car audio spl meter to see the real time decibel level at your ears in your home theater? I believe SSA has a bluetooth one for your Phone and you can place the SPL meter anywhere to better show comparisons between drivers like what DB and frequency vary between subs

They both have internal dsp...Great review though, i just bought two of those monoliths. They are on sale right now for 149 off, so , why not!

I get a little confused here. I mean I know you compared the compression. Monolith still went up 3db except for that one area. So if you were to keep going up. It probably would’ve matched the 16 in all the other frequencies right? Except for the compression area?

Im am SVS guy, but for the price id go dual monoliths because output at 10-15hz is nuts, and for the same price as the SVS you can get almost the same output at the rest of the frequencies but absolutely smash below 16hz. So it it were my money I'd go dual monoliths. Or better yet the Monolith M2 dual 15 sub.

When you watch the movie clips are you at the same volume? If so, you need to match that volume in REW and run the sweeps to get a more realistic view of what you are feeling between the two. Example: if you ran the movie clips at -10 you should run both the SVS and Monolith at -10 in REW to see if you see any differences in the graphs. Even that is not exactly perfect. But better than running one sub with more volume and then saying that sub is outputting more. The reason its not perfect is you have a separate volume for the signal output via REW. I believe I saw it at -12dB from full signal in your video.

im going DIY and 2x 18s cost $1300 @ 30hz 119db! on paper. real world +/- 3db for room gain. none the less thank you for sharing

Hey buddy i just order 2nd monolith 15 so what you suggest with your opinion 1 pb16 or 2 monoliths are better??? What yyou think??? Please unswer me😊

Great review!, I have Denon 4400 looking to upgrade sub which 1 would you recommend monolith 12THX or SVS PB 2000 ?

Yo youthman! I want to start out by saying I really enjoy your videos, they are always fun, entertaining and informative. I have a quick question about REW. I just replaced my SVS PB12-NSD with the new SVS PB2000-PRO which as you probably know has the APP like the 3000 and up. I now have the ability to make adjustments to correct for my room. My question is this I have a laptop that only has one USB port and 2 USB-3 ports. Can I use a USBc to HDMI adapter to send the audio sweeps to my AVR? I would assume I could but want to run it by you before I by the mic and adapter. Thanks for the help and keep up the good work

You should do this demo with Godzilla King of The Monsters. That movie has a dolby atmos reference track. It sounds amazing!!

remember to click the bell lads

it would be interesting to look at the distortions tab of REW - I think that below 40 Hz there are more distortions than the signal, harmonics and the whistle of the bass reflex ports are heard

Where were the subs placed, what was the angle, and what was you seating distance?

Hi Youthman Just wondering if you have ever heard of the Tonewinner d6000 subwoofer, maybe do a review?

Great video as always my man 💪🏿

Thank you thank you thank you!!!! No where have I read yet where to set volume of receiver when doing compression testing? Is there a setting it should be at according to the meters in the sweet or anything to really know what headroom you have and such?

Youthman, You need to check the new GODZILLA king of monsters blu ray or 4k disc. I felt it finally was a movie that does Atmos through movie and well. I just enjoyed watching it because of the sound alone

Another great video Mike! It would be cool if you could make a graph that shows where all the subs you've tested stand against each other.

I don't agree with the assessment based only on peaks, especially when most users will use dsp to correct those peaks. You should also factor in the distortion as well.

Hey Youthman. You look like you just might be the happiest guy on KZfaq. I'm I right?

Like usual an other great video,thanks. You put my thoughts to psa in earlier vids,when you campare s3611 to pb16 ultra. Most just say mein dual psa tv36ipal probebly comes Home to me this week,well i thinking its probebly the first ones entering Sweden,pretty cool:)

Also, you should be installing the ASIO drivers to test the LFE output and not the L&R output as your crossover settings will affect the results. If you didn’t turn off your mains and change the crossover too 250hz, you are measuring more than just the subs in your REW sweeps.

Okay, what would you do... I have a PB4000, one. Should I switch to two Monolith 15's or get a second PB4000? I like the extension of the 15's and I know you said you were not going to get a 4000 to test... I'm torn... The money is not a big deal because I can save up but the PB-16 is more than I am willing to fork out and my wife would beat me if I got two... So after hearing the 15's and your best guess at the PB4000....? Thanks! Great videos!

I’m happy to hear you say maybe some Rythmik‘s. I’m hoping they got back to you this time! If they did and you guys are in the works please strongly consider the FV18SW. It’s an 18” and is the only Rythmik offered with a paper cone driver which they created for HT. It has more TR than the aluminum cone and +3db over 40hz than the aluminum. I just sent a message over there to maybe help sway them to sending you something.

Great video as always youthman

WOW Big Guy!!! GREAT 3 video series! Best I've ever seen! Opinion and fact to back it up. For me I would buy 2 Monolith for the price of 1 SVS. SVS a bit better on paper but MY ears wouldn't be able to tell the difference. DEFINITELY in your best top ten videos!! LOL

I like this comparison. To be more fair though the monolith subwoofer only has compression from 10-about 20Hz which is pretty much inaudible..... after that the 3db you can see is still consistent. Just wanted to point that out to you @Youthman

Based on your findings, would you say that the monolith subwoofer is a more home theater oriented subwoofer than the pb16?

With the monolith was that version 1 or 2 a did you hear any port chuffing when the low notes played?

Id def choose the monolith. Way cheaper too.

Aside from just sheer output, how does the monolith compare in sound quality to the svs subs (ie clean bass, quickness, accuracy, etc.)

Damn Michael I almost called it! I told you I was guessing the monolith would be stronger under 15hz and the pb16 higher on the rest! 😅 15.93hz 👌👌

this helped .. Im finishing up my home theater build and was confused about SVS vs monolith...After watching this im not sure [t[hat I want to pay $1700 more for +5 decibels when the monolith has a lower end

Hey youthman, not sure if you have Netflix or not, but there’s a movie called Operation Mincemeat. The last 15 minutes will destroy a sub. I’m curious how your jtr subs will handle the notes. I have a pb-2000 pro and at -30.0db it almost fried my sub. I’ve never seen my woofer move like that.

Congratulations

How to calculate required watts for a particular room... for e.g.. just heard 20x20 room needs 200 watts power of a.v receiver n speakers then v can feel is it true

Monolith at lower frequency showing noise where PB16 not. Can you correct it? Like PB 16.

Please please please......... review the HSU subs vs some of these!!!!!!!!!

So the monolith digs deeper than the pb3000 and the pb4000

I've heard and felt that after a certain amount of money spent on audio equipment the more spent the less you get back from the equipment once you have made it to a certain level of quality or spending

Does it help with the out put when you have two subs instead of one? Would the numbers be different on this video if you tested two instead of one?

Youthman, could you please compare the monolith 12 and the 15 ported ones. Have heard some say that although the 15 is louder, it sometimes is not as tight as the 12s. I would really love to listen to the facts from somebody like you who really knows what they're dealing with
