Who has time to watch TV anymore? We are way to busy watching Obsessed Garage. Great job on those speakers. I picked up a pair of towers real cheap as they had a rattle in them. The speakers looked new but I planned on replacing them until I removed the woofers and found kids toys in the darn thing.

I wish we could clone you so you had time to make Obsessed Home Theater. Your level of passion/knowledge for this niche is greater than 99.9% of the current KZfaq channels.

I have probably run audyssey 100s of times on my own home theater and in reading numerous threads and running tests what I found is that you actually get a much more accurate reading from that system by making small movements of the mic from the center seating position instead of doing like they show you. So instead of moving the mic all over the place, find your center seating position and then move the mic from there about 12 inches each direction, my results for distance of speakers and levels and overall sound was much better.

You will need some delay on your rear subwoofers, and you might need to reduce their level by almost 6dB compared to the fronts. This makes the case for having SPA1200DSP amplifiers on all four subs so you have the DSP tuning flexibility.

If I may humbly suggest brother Matt.. when you run the audio calibration software, it is better that you exit the room (close all doors and remove large items not permanently occupying space) to get a more accurate reading from the audio chirps that bounce around... Just a thought..

I sure do love these home theater videos and i still want to buy myself one of those subs. I really need a decent sub but such is life. Great Video as always, Matt. -Stay Blessed

It's very hard to make the subs in the back disappear, I know feeling the bass closer may want us to place the most powerful one in the rear but, I would put the most powerful in the front and tune the rears just for ambience and low volume or output. Or all subs in front near the screen. Home theaters are a nightmare to tune, room acoustics and many issues that it can never be perfect, and when you listen to just music, cds it's hard to pick the best mode on the receiver. After the tune is done, sometimes it may be better to make sure a good DVD concert or studio tracks sound good with most music coming from the front as if you were in front of a stage. The old over 15 year Steely Dan DTS DVD could be a way to know or learn if all the instruments realistically sound where you see them. Good luck and sometimes the best would be as good as it is going to get for home theaters in rooms not designed for theaters 👍🏻

It there was ever an example of you striving for excellence, that room is it!

Look into something like a minidsp SHD for just managing the subwoofers, the dirac suite can do just bass management. Also can do your PEQ through dirac too, I get around 16hz in-room before THD starts to rise after PEQ.

Nice work building the subs. They look great.

The subs look amazing!! I notice it looks as if you're bi-amping your fronts. Also, I hear the JTR is amazing.

1:10 gotta love The Grand Tour

Love your setup. Lose the cabinet or get a smaller one, center channel on the wall, left and right speakers inside of subs. You should get into DSP. It's complex at first but once you learn it, it's SO powerfull and the results are like nothing you've ever heard. IIRC filters . I'd LOVE to calibrate a home system like yours. Just to see the look on your face when you hear the results. Even 100 seat Atmos cinema autoria don't have 4x18" subs. If you upgraded to Atmos, you could use the subs as surround subs. The way Atmos handles bass is pretty impressive too. It makes even mediochre sub systems slam in a very characteristic way. You KNOW you're hearing a professionally calibrated Atmos system. A good sound stage is entirely down to the accuracy of the time alignment between each component. An accurately time aligned system, between individual components (everything needs to be bi/tri-amped for active crossovers and phase correction) with good room compensation and node cancellation will not have a sweet spot, the speakers dissapear and you are immersed in a highly detailed sound field. If you really want to spend some money on a serious piece of kit that is (in my opinion), the best sounding processor money can buy, the "Altitude" range from Trinnov is the one. It's like experiencing surround sound for the first time again. Trinnov are rapidly taking over the cinema sound market from Dolby, because it puts Dolby's Atmos installations to shame at 1/2 the price. It's the only processor on the cinema market that has the ability to accurately time align any room and calibrates itself. I don't know how much the Altitude is, but I know the cinema version - "Ovation" is around $4000 and supposedly less than the domestic version. Way out of my price leage ! It's one of those things that once you've heard it, you HAVE TO HAVE ONE ! Or DIY something to achieve something similar.

The earth beneath you Matt will certainly move those mammoth X4 Dayton subs. Very nice project!! 👍 Thanks as always......

I use a dayton audio umm6-1. I calibrate reference volume to 75db. I calibrate each sub to 75db via the gain knob on the subs them first with pink noise and reference volume. Then after each sub is at 75db on there own, i run them all together and adjust the level trim in the receivers itself to 75db cause each sub is gonna add 3db gain i think? So i trim that to play 75 db and it really helps a lot. Sounds so smooth. I have a similar room to yours and i also use REW to see what the room looks like on graph. Messed with some phase controls and that helped also. Its a process and im learning just like u but when it gets done it makes a difference. Every seat is a good seat. Lol. Have fun and take care.

I got my first kit parked on the garage floor ready for some glueing now ^^. Gonna test it and if it performs as expected I'm going for 4 more, stacked 2 and 2 in each front corner. Will use an external amp though. Tremendous amount of bang for the buck compared to premade solutions and easily as good sound. Congratz on finishing the subs.

you may have to get some sort of system to time align your subs so they move in one motion correctly. and make sure all the phasing is correctly match

Really enjoyed this man, nice!

I ran a sub that close behind my couch once. Though its not "supposed" to it did seem to rebound sound back into wall then back up. Almost echoing the bass and made it sound boomy. I ended up turning volume on sub amp(dayton) down lower and on reciever. May also try playing with phase a little on rears. Just my opinion though. Nice setup.

Great video and I really like your room. I just bought two ultimax 15s but my room is much smaller than yours. I’m trying to decide between plate amps vs rack mounted.

Seeing as you already have power amplifiers under the center channel, you should look into the getting the Monoprice/ATI HTP1 with 16 channels of Dirac (including auto subwoofer management for 4 subs).

awsome setup... what did you use to calibrate 4 subs?

Great setup!! Top of the line for sure.

Just now seeing this video. I am not sure if you got this system dialed in yet or not, but have you tried delay locating the subwoofers? I learned that with adjusting the delay among the subwoofers, you can focus the position of the sound around the room.

If the OLED is a 2019 model there's no problem with audio compression anymore it finally passes through with the new HDMI 2.1 specs

DAMN! You do things right!

Im just sitting here thinking what which approach i would take and i keep going back to time alignment between the front and back subwoofers. I would right off the bat try playing with distance or phase to see what difference it makes, then building from there. At least until your friend comes and helps with the tuning. That amount of cone surface area and wattage should blow you out of the water from every angle, so definitely cancellations are happening.

Nice room. When you have your system calibrated, I'd almost guarantee that a Minidsp 2x4 HD will be used. It'll allow the subs to all be in phase with one another, and time aligned so that they're hitting you at the same time. Once that happens, poof it's like a genie just gave you three wishes and you used one 😉😀

Very nice set up! I think I may try a DIY Dayton sub!

cool setup, Im jealous and your daughter is adorable!

Get some of those off the floor, raise two of them up at least 8-12" . This will produce a beautiful clean sound by not firing a large percentage of the forward bass wave into floor. Audiophiles and professionals say putting the subwoofer on the floor is like putting it in mud.

Awesome!!! A lot of base.

Beautiful work with the subs! Was there a lack of bass before???

hey matt! you share my love for home audio. I would definitely suggest running some simple Room EQ Wizard(free tool) sweeps and you'll know the best placement in 30 mins. It's really hard to truly tell without measuring with a tool. Wish I had the patience to build my own equipment. fire up a laptop and you'll get it dialed in easily. I wish the streaming apps didn't all compress the audio to hell...I have to stream my local files to get the true audio experience or the equipment is somewhat wasted.

Absolutely love Revel speakers. We install a lot of Marantz and Revel together. They are a great combo. That incredible midrange with all the detail from the Marantz . Those look like Sunfire Amps? They also compliment the Revels nicely. Sweet system.

Any more updates after this video came out?

Awesome more of this!

Really hope u can do Calibration videos. I use Blu Ray as a baseline for testing because it helps me visualize the system in my head while testing

You have some very nice equipment love your insight love the video

Are there any specific websites, channels, or videos that anyone recommends to learn about home theater? I want to get into it, but it seems so overwhelming.

Check out Multi Sub Optimizer. It was designed to integrate multiple subwoofers in one system. It's got a steep learning curve but the results can be amazing. I've got 2 of the same subs and a pro amp, MiniDSP 2x4HD and Audyssey XT32 and spent months between MSO, Room Equalizer Wizard and Audyssey. MSO is definitely going to get you the best result here, try it if you have the time. If not - run the front subs as one sub seen by the AVR, and the rear subs as the second sub as seen by the AVR and it'll probably time align them better. Without a microphone and REW you're just guessing, though. Good luck!

Nice setup!

Wow great setup man but What's the purpose of all those boxes on the wall?

Media room from whoom you expect stellar performance YET you have 1 000 000 sq feet of glass and windows. But this room is NICE. Enjoy daughter is spending time with you and you have the woofers to play with.

Sweet new outro!

Sick setup

Team Dad Duty!!!!! I do understand. My wife is getting comfortable with Dad Duty.

best option for sound is simply a tosslink optical out. i only usr ARC when ive adjusted something

I have a aiwa mini hifi system that has a subwoofer output and plan on getting 4 subs for it to add that earth shaking bass I plan on getting 3 Polk audio psw10 subs and 1 monoprice 8 inch subwoofer can't wait

Don't forget about crossovers on the front speakers. If it sounds off still, try messing around with the front speaker crossovers/Audyssey and removing all the bass from them and see how it sounds afterwards. That should help get an idea of what's causing issues. If you have cancellations/odd sounding bass with the speakers at your normal crossover point, set it as high as it can go, then see how it sounds after, if it clears up a bit, then play with phase and check out other crossover points and then Audyssey the bass out of one, then the other to determine which one is the culprit. In my case my left speaker even though it's just a bookshelf speaker (Chane A1.4) it was interfering with the subwoofers bass around the 60-80hz area (Ultimax 18" in a Full Marty) and after setting 63hz and 125hz (all my Audyssey lets me do) to -20 on the left speaker, it has helped the bass quite a bit. It was an interesting work around, but for my room, it's what worked best. Anyway, hope you enjoy those subs and can get it tuned to your liking. Everything below here I'm just blabbing pointlessly and can be ignored lol Also I feel the sealed cabs they offer area bit too small. I'd personally rather have them in a 6cu and give it 1.5 to 2db gains in the 20hz and below area. or 1,000 watts to get 96.6db in the 6cu box vs 1.600 watts to get the same 96.6db at 10hz in the 4 cube box. (Free performance, except you have to cut the wood manually lol)

That outro is clean bro

What model is your Marantz receiver ?, how does pink Floyd sound at 3/4 volume ?

What coating/paint/finish did you use for the Sub boxes? It looks extremely durable

How are you liking them so far? I am thinking of doing 2 of these in the front. Wondering if that would be the best bang for the buck vs. buying a premade sub.

having the GTR sub will acct.screw with your audic. it will suck up sound so when you move it you may need to run it again. :)

Very nice setup!! You build an DBA (double bass array) right? I think you need some delay on your rear subs. Could you do some measuring? I´m very interrested how deep your 18" ultimax can play in a not vented box. I run 1 ultimax 12" in a vented 4 cubic feet box at 18hz.

Bro love that new TV. Next time we meet, you'll have to show me your theater. I have a awesome Polk setup we can talk about

Calibration tech informed me it's required every 90 days (special discount just $4,700 each time) to prevent drift. He got me a great deal on whole-house rebuild with acoustic grade drywall and full re-wire with Nordost Supreme Reference wiring because the Kimber Reference Romex had run it's course...

Normally 2 sub channels are not 1 and 2 but left and right. So you might be getting bass thats suppose to be stage left coming from the front and right stage coming from the rear. Or vice versa.

AWESOME BRO

I've played clubs that had less power than this :O:O

I love the home theater videos and oh Comcast how everyone hates it

Good experience bro ,but your room very small ,and your cute little daughter so beautiful ,God bless your family,

Is there any benefit in using balanced xlr connections to your subs over rca?

Hey Matt, Did you give a look into the Martycube DIY build? I built 2 cubes use them as end tables for my couch. They are similar to your design but ported and very easy to build. I run Daytons in mine but the Ultimax seems to be a good option nowadays. They sound absolutely insane. I also have 2 12"s up front in my B&W towers also. I do this type of thing for a living, have done for 10+ years. Home Automation. Savant, Control4, Crestron. If you have any questions shoot

Nice video!!! When ever you have multiple subs, never run them on the different amps and crossovers. It's very difficult to get them to play together, you will most definitely deal with some bass cancellation. Whenever you are running multiple subs, it's best if you have an external multiple channel amp and an external multiple channel crossover. Have one signal going into a 4xchannel amp and you signal going to the crossover. You need them to play together pushing all at the same time like a car stereo system with multiple subs. The way your setup is, you'll have more bass from one sub than all four. Simply put, run everything through one multiple channel amp and one multiple channel crossover. 🙋🏿‍♂️🤸🏿‍♂️

do u use that gaint dual subs in the left corner of the room two or just their for show it looks huge and bad ass

Have Jeff from accucal come down to calibrate screen and audio. Well worth it. He did two of my tv’s and my home theater. Best money I spent. It’s like a tune up for your car but for the theater. Enjoy!

Have you played around with putting the center channel on top of the intertament center just see if it sounds better

Matt, if you sell the JL sub let me know as i might take it off your hands.I forget if yours is a ver 1 or 2, do you know?

I absolutely love your content and you have a very precious and beautiful little girl 🎉🎉

Dang. That’s gonna thump

I can use your advice, 2 months ago I purchased 2 SVS 12" PB 1000 Pro Subwoofers, They sound good but it's stil something missing, I was thinking of getting a 3rd PB 1000 Pro or would you sell and get 2 SVS 12" PB 2000 Pros?

Output wise, how do those 4 Daytons compare with the single JTR?

The 65 inch LG OLED is nice but your audio system demands a much larger display. While Samsung QLED doesn’t quite match up to LG OLED, a Samsung QN85Q900RBF display, which could be sold or traded later, would work well until LG’s OLED 88Z9PUA becomes available. Two old movies, Bullitt and Grand Prix, would be awesome on your system.

Hey Matt any particular reason you went 18 vs 15? I dont if the size makes that much of a difference.

I did bass shakers vs rears. They are cheap and you already have the amps etc... Much more tactile and no echo from being in rear corners.

Did you sell that jtr? Im interested

Curious if you tried the SVS subs? Also.. I dont know why..but I am thinking an automated slide down projector with a 4K laser projector is needed.. maybe 140" screen.. though cant tell the distance between couch and screen so maybe thats too big for the room? Nice setup though!

REW and use the DSPs to tune for flat curve

Nice theater. The center channel may get reflections from the doors when open.

Next up see if you calibrate your TV with Calman. That's the software I use

All your really nice gear lends this review massive credibility. Would you recommend a pair of SVS SB3000 or Dayton kits?

Thinking of going from 2 to 4 subwoofers as well. But my Denon only has two sub out lines and worried about calibrating them to sound good....

So. You won’t do DSP?

Any future plans to do another car audio install on one of the M cars or the RS?

Level match your subs individually at the listening position with a dB meter. Can even use an app on your iPhone as a reference. Buy a miniDSP, a mic and download REW. Anything short of this and you will never get the performance it’s capable of. Short cut it by finding the ideal spots in your room to place the subs. The corners aren’t it. Look up sub crawl if you don’t have a mic and REW. phasing subs to your mains is critical as well.

If you want to hear a extremely low bass frequency play "Edge of Tomorrow" intro w/ credits👌

who's your calibration guy? how much does he charge?

Love it - what about a bigger TV?

The audible chirps (waves) are influenced by any object (including yourself) they collide with..

Is that a custom cable? Looked like dual xlr to female rca... is it a significant difference in audio quality?

Hey did you ever sell the captivator 4000ulf?

I need one

Hey how can I get the 2 subs in the box

That jtr behind the couch and the others in each corner,I wish I can hear that or feel)

Hi Matt, Were you happy with these DIY Build Subwoofer? At this moment I think about buying a JTR RS1. But I think about build a DIY Subwoofers with Hypex plate amplifier and Dayton Driver too. Additionally I would build a Cover for the Speaker.With magnets. The RS1 cost at least 3300$. I always prefer two Subwoofer.Not more.But two. What do you think?

they don't look DIY, they look store bought. good job!

Trying to be like Todd Cooperider with that home theatre

Just saw you on tommyfyeahs channel, have you done an update on this set up?
