Status Update: Got the screen mounted, columns framing is 95% done. Audio wiring should start tomorrow.
I ended up using about 90 2x2's for the columns.
The remaining 5% of the framing is the projector box details.
As far as audio-wiring goes...
DSP-wise it is 7.1, but it is wired for 7.10 (all of those channels are bi-wired BTW
Because of the bi-wiring it could technically be configured for 29.1 or 28.2 surround sound if I really wanted.
and if have enough wiring length left over after doing 7.10... I'll try and aim for 11.10 (i.e. 4 extra wires).
Man this room makes my 120" screen look tiny compared to my narrower old room.Edited by BassThatHz - 2/2/13 at 11:24pm
