This is my 3rd theater thread on here and my 4th theater.

First, I had a small theater in a bedroom. We had a 2nd child and I had to move it into the garage. Here is the thread for that theater: http://www.avsforum.com/forum/29-what-s-your-system-configuration/1135118-my-budget-ugly-garage-theater.html

Then, we bought a house and converted a larger bedroom into a theater with an acoustically transparent screen installed in the wall and theater seats. Although I had all of the electronics I needed, I never got around to installing the surrounds. However, we got a ton of use out of the theater with just the LCR and sub and the theater was one of the main things that sold the home. Here is the thread: http://www.avsforum.com/forum/15-general-home-theater-media-game-rooms/1427533-jedirun-s-theater-finally-moving-out-garage.html

We are in the process of moving from San Diego to Ohio. We purchased a new house. Part of the purchase included finishing part of the basement at the builder's cost. I am having a dedicated room built for approximately $5000 including a false wall for an new AT screen.

So far, it is framed in and I have installed the speaker wires, XLR cable for my sub and HDMI for the projector. I will document the rest of the build and installation here.

I am going to do less acoustic treatment in this version and I am having my wife do most of the decorating including picking paint color and sconces so that she can enjoy the theater more.

Framed, Running Speaker Wires

Framed including Bathroom, Equipment Closet and Utility Closet. The effective size of the room left over, not including the area behind the screen is 17' wide and 21' long.

I have a question:

My whole front wall will be speaker grill cloth and my LCR and sub will be behind it. 4 feet behind the false wall is an untreated concrete wall.

My goal is to provide as much treatment as possible without having any of it visible in the room since my wife said that all of the GIK panels I had in my old theater, ruined it for her.

Would putting regular insulation behind the speaker grill cloth, between the studs be useful? Should I look for a particular type of insulation? is anything that would work well available at local home improvemt stores or should I buy specific raw materials like Owens Corning 703 online?

Thank you in advance.

This design concept has popped up a few times over the years, here are the potential issues

Out of sight, out of mind, could be an issue if you need to sell the house, you really can't call it a finished space. If the buyers inspector spot it they will call it out.
Not sure if it meets fire-blocking building codes in your area.

I've always encouraged theater builders to bite the bullet and drywall the front wall even though it is hidden. Add acoustical treatments on top of the drywall.

Since it is still under construction, I can probably get the front wall finished

Are treatments on the dry walled front wall more effective than insulation within the screen wall?

Acoustic treatment question:

The plan is to treat the whole front wall behind the screen with linacoustic or something similar and to make sort of a box around the speakers with my existing DIY and GIK acoustic panels. The floor will be carpet, the walls and ceiling will be drywall. I am trying to keep any visible treatments out of the room itself for WAF, but I can do whatever I want behind the screen wall.

Would anyone recommend that I add any sort of treatment behind the grill cloth fabric within the screen wall itself?

New pictures of my theater, pretty much complete other than equipment. The equipment is still on its way from California. My new screen will be here on Tuesday.

I will try to get the acoustic treatment before my stuff gets here in a week.

The screen wall is pretty much completely transparent when the light is on behind the screen. If it is still transparent with the screen in front of it, I may try to take advantage of that and light the speakers behind the screen to show the speakers off.

However, I am going to fill the rest of the space between the studs in the false wall with Roxul Safe N Sound.

The rest of my equipment from CA should be here are some this week, so I may get to get started setting up next weekend depending on how much we get done unpacking during the week.

Here is the false wall with the lights on behind it and my assembled 115" Seymour AV screen.

Functionally the theater is pretty much done. However, I still need to do some aesthetic finishes and a ton of cable management.

Right now my surrounds are taken apart and have been painted. I will put them back up this weekend.

I had only one significant setback during installation. The HDMI cable that I installed in the ceiling didn't work. I bought a new one from Monoprice, pulled the old one out while pulling a steel tape in and used the tape to pull the new one in. I am amazed it worked, since the original was running through 1 inch holes in the ceiling joists.

I ended up running out of time and money in the initial build so I didn't get the front wall behind the screen finished. I put Roxul safe and sound insulation in my screen wall everywhere but in front of the speakers and used all my old panels behind my LCR and sub, so there is a ton of treatment of the front of the room and no treatments anywhere else. That may not be the best or recommended way to treat a room, but it has a higher WAF in my case and it sounds awesome. It may be that I am getting away with it due to the toe in and controlled directivity of the horns, but who knows.

I have attached a bunch of images of my progress.

As you can see the equipment closet is still a mess.

The inside of the room actually looks a lot better now than it did in these pictures. I will take some more this weekend after I put the surrounds back up and touch up the paint.

I also added a Harmony remote that works with an app on my phone. It took me a little while to figure it out, but it is working well now.

The other new component I added was a Mac Mini server. I had it in my old house, but was not using it with the theater. It has been good to have it directly connected to the processor for both music and YouTube. I will probably be using this to stream video from Amazon rather that the PS3. I have an extra monitor in the closet that mirrors my projector, making it easy to use.

Another weekend or 2 and it will be all enjoyment and no more work in the theater, at least for a while.

A few more pictures.

After I touch up the paint and rehang the surrounds, this part of the room will be done and I just need to spend some time dealing with the rats nest of wires in the closet, rerun Audyssey and do a minor optimizing of the video.

I am really happy with the column that the builder put over the beam support.

It will probably be a while until we buy a back row of seats, but at least the riser is done.

The sound is pretty amazing. It doesn't seem like we need any in room treatments. Of course the speakers are amazing. I have not had upgradeitis ever since I went to the 228's and Cap S2.

Although our screen is a little larger than my old one, Even at 115", I think we went a little too small for the room, so I might have to replace it.

I came across my thread in my subscriptions and I realized that I never got picture up of my surrounds installed after they were painted.

I also added more Roxul to the top of the screen wall and covered up the back of the screen wall with speaker grill cloth to keep the cat from climbing up the insulation. I was finding pieces of insulation on the floor.

My hope with all the treatments that the screen wall and the space behind the screen would act as sort of a giant bass trap.

I don't know if the science bears that out or how it would measure, but it is not boomy at all even without any in room treatments and it really sounds great.

I have had no thoughts of upgrading since it was finished two years ago. That is saying something for me.
