Matts DIY Home Theater

I initially had this posted in the media game room thread and thought id start a new thread here as my room is now mostly a theater. This has been a long time in the making. I belonged to this forum club when I was 22 years old wishing I would have a chance to build my own some day. I was living with my parents and couldn't see the day I would have a projector with amazing speakers etc...

The first dive into this was when I rented an apartment and finally had the chance to take a baby step. I hooked up my first surround sound which was the logitech z5500, a computer surround sound system It was all I had and could afford and didn't want to piss off the people upstairs. I loved it! It reminded me of when my dad and I played around with surround at his house and couldn't get enough. It was at this moment I knew I would have something good some day that would put my little computer speaker system to shame.

Jump forward 10 years, 3 career changes, and 5 kids later. I now have a basement with the beginnings of a setup that will be awesome for me .

equipment to date:

receiver: Pioneer SC-LX502

speakers: fronts htm-12, surrounds volt 10s, heights volt 6s

subwoofer: 2 vbss pa460s

amplifier: inuke-1000 dsp

media: custom HTPC running Kodi and able to rip and convert blurays

screen: DIY 120" diagonal spandex AT screen white over silver


Right now I am in the middle of finishing my other VBSS sub and all the volt speakers. Im also working on my 16ft stage area as well. After this is all done then on to convincing the wife that dd, clips and glue are 100% necessary for fire safety in the basement lol! I'll post some pics.

Here was a picture of what I had set up for a couple years minus the htm-12s and sub. I initially had NHT speakers that my father-in-law gave me. They were good, but nowhere near the htms. PARDON THE MESS! My wife has been using the basement as storage ever since the htms didn't fit behind the screen!



Here is the layout of my room and what I want the completed look to be. Im missing one false wall on the other side of the screen. I forgot about that when I was using the layout app.



This is the wall right before I took it down. I had the NHT's behind the screen on some rough stands I made with the pocket jig.




Ill post more pictures tomm if I get a chance to work on it.

Looks like a cool set up. I’m sure they exist, but I don’t think I have seen a theater optimized for bar viewing like this seems to be.

I'm thinking of also making the bar structure a cabinet for some subs that will face the back of the front seats. That's a little time in the future but that's the plan. I also make concrete countertops and this will be one large one!

first row seating appears to be at 1/2 room length. There will be a bass null in that location, turning it up won't help. Putting one of your subs on the right wall just in front of the bar will.

Just a thought.

Why not reverse your room.

So I will be 10ft away from my speakers and 12ft from the back wall from the listening position. Is that not enough? Maybe I can have Dts dig over to measure my room when he comes to check it out. I'll move the sub there to see if it helps as well.

The problem with this setup is the ductwork comes down on that side of the room. There is no moving the ductwork either. That cuts that space down quite a lot for any overhead speakers etc...

Ah, I thought you were just sharing your work, I didn’t realize you were asking for suggestions!

Anything to make it better everything I've learned about home theater was from you guys. I definitely will take any and all advice.

So this is a cavity created by the false wall. Would you stuff this with insulation? The walls are already going to be insulated. Not sure if I should fill the void.

any cavity adjacent to the theater walls that is created by theater construction should have some insulation to mitigate cavity resonances.

It is wall to wall, doesn't matter where the speakers are. Also can't tell but any wood that is in contact with concrete either poured or block should be pressure treated.

All wood in contact with concrete is pressure treated. That stinks about the middle of the room null. I knew about the middle of the room as people bring it up here all the time, but just didn't click with me until now. I cant change the listening position unfortunately. Ill have to wait on measurements to see where the subs sound the best with my setup.

Ok. Ill make sure to put insulation in that space. Maybe putting r30 on the false wall that backs into that space would suffice. Basements in NY suck. Mine has been great since we've owned our house, but I don't want to make it bad as far as mold, mildew growth so I may have to contact someone to find out more information about insulating a basement here.
