The Cmoanz Theater/Basement

I, like many others, have spent countless hours on AVS researching our home theater build. I followed the excellent build examples from BIG and others here. There were some compromises along the way for budget, HVAC and WAF, but I very happy with the end result.

I would have been lost without the invaluable resource of AVS Dedicated Theater Design & Construction, hats off to all of you that designed my theater without even knowing...

Goals:
  • We have a family of 5 (Wife and I plus 3 boys ages 5-12) so we wanted 5 seats min.
  • Wife wanted no visible speakers, so this called for AT Screen and in-walls
  • We watch a lot of TV and some moves and games so we decided on a 16x9 screen
  • After much debate we decided to leave the theater open to the basement on one side and not soundproof.

Current installed equipment:
  • Falcon Screens Vision HD 16x9 FVH110 126"
  • Sony VPL-HW40ES Projector
  • BIC-FH6 LCR
  • GoldenEar Technologies ForceField 5
  • MTX Audio Blueprint HT520BDP (LR surround, in-ceiling)
  • Martin Logan ML 65 (Rear surround)
  • Denon x4000
  • PS/3
  • DirecTV HR24
  • Apple TV
  • Lighting control: Insteon
  • Remotes: iRule

Here was the initial basement design from the contractor (the final design changed a bit as you will see in the pictures), The area for the theater measured ~14' x ~17', with a height of 86". The dotted line on the at the opening is a steel beam that spans the walls at 72":



After some rework we decided on this as the final basement layout:



This left me to design the screen wall/staging. Here we deviated from the more common AVS stage and simple screen. We wanted more of a finshed wall look around the screen vs. the GOM fabric snap in's that alot of people use. You will see the end result is fully drywalled.:

Reserved: Framing and Testing

Framing began in September, and one if the first things to manage was the HVAC runs. We have a two zone system, and there was one trunk running down the middle of the basement very low (< 70"). We wanted this moved and re-routed. That trunk feed the room directly above the theater area. With the beam in the way, the only option was to create a soffit and running the HVAC behind the screen wall to feed the room above and the theater area.





After the re-routing:


Screen Wall before the staging:


Screen Wall with staging:




I did some pre-drywall testing of the projector:


Tested several screen samples from Falcon, Stewart and Seymour:


I had a thread for this on the Screens forum

Drywall starting in October:








Here you can see the surround locations. Given that we were missing a wall, I decided to compromise for now and go with in-ceiling for surround. Two in middle are pre-wire for Atmos:

Reserved: Finishes and Results

Primer and Painting... Tricorn Black and Cityscape Grey














Carpet and Trim installed:



Five Fusion Jive Seats from RTheaters... As you all may have heard the stories about Roman are all true. He's awesome to work with and the Fusion's are great.




Linacoustics RC Installed on the back of the screen wall:


Seat moved in, they will be positioned more forward soon:


Falcon HD Vision AT screen 16x9 126":









Turns out lesson learned... the bands do NOT need extra tension... they should be set to pull straight down vs. the way I did them here (which creates ripples in the corners)


Also do NOT over tighten the top corner brackets, they will break. Rich is awesome, he will send you a new one if you ask nicely!



Screen Wall with speakers installed:


DIY Speaker Stands:




First system demo for the boys:

Wow - looks great! That screen shot is amazing. I bet the kids were almost as psyched as you.

How are the 5 seats working out? I have a family of 5 and a small basement. I need at least 5 good seats for us but I'm a little concerned that if I only have 5 seats it won't work well for company, etc... not that I have a lot of people over all the time or anything but it would be nice for football on Sundays or something. If I allow for more seating I'll lose out on valuable real estate for other things (arcade cabinets, table, shuffleboard, whatever).

Great job!
does the sub move the screen at all?
How far is it from the screen?

For us the five seats are perfect, right now we also have 3 bean bag chairs in front of the five. Sometimes the boys are there, sometimes not... The row of five is ideally positioned for the screen but not perfect for the surrounds. We are a little close to the rears and not ideally lined up with the RL surrounds. The in-ceilings are di-poles which makes them a bit harder to localize so that helps.

With the Fusion seats we have option to convert to a row of 4 |0|0|0|0| or |0|00|0| with a bar in the back but think we will live with this row of 5 config for a while.

Thanks!

The sub is 5" from the screen, it does not move the screen.

I guess I will wait and see how the content goes. There's not much out there today that would drive me to upgrade receivers. I think my next upgrade will be on the equipment rack ( have a small network box and a Menards shelving right now ). Then I think I will replace the BIC LCR's with something from DIYSoundgroup.

Really nice job...It looks like a great space.

I am curious: Did you leave the speaker grills on the speakers behind the screen??

I believe the grills reduce output by 3db in most applications, at least they did on mine.

Might be worthwhile to take them off.

Jgourlie,

Thanks, I do have the grills on, I was worried about the reflect from the silver cones. I will test with them off to see either way. I need to run Audessy still but things sound pretty good on manual setup right now.
