Obviously everything has yet to be calibrated. This is at the brightest part of the day in a room with west-facing windows and simple blinds closed.

One piece of advice, not sure if any one suggested it yet.



Build in ventilation behind the wall unit that will hold your receiver. If the projector will be fully enclosed to in the ceiling, same thing applies. A few small vents with a fan should be enough to keep the equipment from over heating. I can't tell if your plans are to enclose all that behind a door. If it stays open as such now then you should be ok. Im assuming your going to have it behind a door so the lights of the devices does not interfere with watching movies.

I'll likely be going the DIY route on acoustic panels. I'm planning on "Superchunk" corner bass traps in the room's three usable corners, the underside of all of the soffits will get 1" Owens Corning 703 rigid fiberglass board, and the walls will have several acoustic panels made with 2" OC703.

Two new circuits wired in from the main box, one for electronics and one for lights. All but two of the recessed lights are installed and all wiring is run to the switch box and is ready to be hooked up. I need to finish up some trim and repair some drywall and I'll be ready for paint. Then I can tear out the carpet, build the riser for the second row of seating and I'll be ready for carpet.

Then I'll finish off the screen wall and install some acoustic treatments. That should about do it...

It looks promising, but I am reserving final judgement for the final product. Wont know if it will look good or cheap until then.

Really looks like you're doing a fantastic job. Having just built a home theater myself a few years ago I know what I headache it can be to do it right. I know you said you were going to go the DIY route on the acoustic treatment but if I might suggest another route, I think you'll end up much happier in the long run.

There's a company called Primacoustic out of Canada that makes some of the finest room treatment available. They are expensive but their effectiveness is second to none. I invested almost $10k in room treatment from them and am really thrilled with the results. My room measures almost completely flat with quite a large sweet spot. The ceiling cloud we installed made a world of difference too!

Laminar, when the thread started you had picked out a 7.2 audio system. Are you sticking with that?

What I'm thinking is while the room is still roughed out, you might allow for a 9.2 system in the future. Plot out the extra/revised locations, and pull all needed wiring.

Also, you could leave a location and outlet for a beer launching fridge.

10k in room treatment for a home-built theatre room? Sure it's important, but might possibly be more than Laminar has invested in the entire theatre room, top to bottom. Unless he's also sticking 10k of high-end audio equipment in there - and he's not - it would be ludicrous to spend anywhere near that kind of money on room treatment IMO. A grand or two, sure...at most.

I'm hoping those treatments will help get rid of the bass dead zone in the center of my room. If not, I might have to get more drastic.

Sorry, missed some of the important info at the beginning. You said the room is 22'x20'? That's a bit too square for even bass. No wonder you have a dead zone in the center, you probably have a wicked mode response going on and have exaggerated bass on the outside seating areas too. The traps and room treatments will probably help, but you might also need some EQ like the Behringer DSP1124 (@$100 from most places).

The full room is 19'x15', the false wall is about 18" off of the main wall. The first row of seating is 10' from the screen, which puts it about halfway between the front and rear walls, which from what I'm reading is not the ideal place for bass response. We'll see how much it changes with new carpet, bass treatments, and furniture.

But yes, I'm definitely getting the exaggerated bass around the outside of the room, most noticeable when standing directly under each soffit's front face.

A suggestion for one set of your seats for good control. Much easier to deal with then remotes.

I advise against touch-screens for home theater purposes. You want to be looking at the screen, not down at your armrest.

Agreed.

For watching TV, you need at least physical buttons for volume, channel (including numbers), and guide navigation.

For watching movies you need physical buttons for volume, play, pause, forward, back, slow motion.

So with all those buttons, what's left other than source selection. I say get a Harmony remote from Logitech.

Also, when the technology becomes obsolete or incompatible with whatever system you have, you now have a chair with an integrated piece of uselessness.

I agree, but make sure it can control the cursor too (I'm not familiar with Harmony remotes, do they control the cursor?). Hardware buttons are really great until there's that one thing you want to do that wasn't pre-planned for. Having cursor control is an easy catch-all, and you still don't have to look down to use it.

Looks good! Maybe he's got some nice curtains picked out that match that blue FA.

Re the doorway: A pocket door might give better sound/light insulation than a curtain, but have no idea how hard it would be or even if it would fit in with Lam's master plan.

I had no idea what his actual budget was so I was relaying my own recent experience. I think the gear total for ours was somewhere around $40k including the wiring.

Yes, clearly your gear was too expensive to bother reading this thread at all before talking about it. Or maybe you wouldn't be recommending "room treatment" that's probably double the cost of his entire project?

Moving on.

Also love the dropped-soffits ceiling - hides the projector perfectly. Colour wouldn't be my choice but that's an easy fix down the road if you ever get bored of it. Question re: the audio setup - what's up with the dual subs? Hahaha, not overkill, or do you just love bass? :o

Tip for Lammy with the subs: Put them where your chair is. Fire the system up, play some stuff. Move your head around in the vicinity of where you think they're going to live. Where your head is when it sounds best is where you should put them.

and a pain in the ass. It's great when you can set them in the same corner, but in separate locations you often need some good EQ and traps to tame the spikes.

The first number is the number of speakers. The number after the period is the number of subs. They're not fully counted because they are not separate channels. Instead, the low frequencies are extracted from the real channels and rerouted to the subs. A hypothetical 5.4 system would have 5 speakers and 4 subs.

There's some arguing over what constitutes true 7.2 - "purists" say you have to have separate left and right sub channels for it to be called 7.2, otherwise it's just 7.1 with two subs. In my case, my receiver has dual sub outputs, but I believe they're identical signals.

As a functional unit if you have space, not only will it allow for enough popcorn on demand when you have guests but the smell from it making in the room will add to the movie experience of a theater.

I'm curious myself why the industry is going to multiple subs. Is it for more bass power, or can people actually tell where low frequencies come from? ie - so you need left and right sources.

I'd long thought we went to a separate subwoofer because people could not trace the source. So one good big woofer, and all the other speakers become more manageable (smaller, lighter).

An engineer who can actually build things? My head just exploded!

Excellent work Laminar, soffit lighting is a nice touch and I love the 'stage' area under the projector screen. If you need to fly anyone out to Iowa and pay them handsomely to build some custom cabinetry I'm your man! Hehe, in all seriousness you seem to have a pretty solid grasp on carpentry and I'm sure that room is going to look amazing when it is done.
