I have a Dual 8" In wall sub that I was thinking of installing under my seats or on the front of my 10" theater seat platform instead of in the wall. My room is 12x19 with a 120" screen on the front. I can Not install it in my wall that my projector is on so my options are in my 2x10 platform I am building to set my theater seats on (Basically I would center it on the platform and it would be pointing toward the screen) or in one of the side walls. I am not sure if it would be better to for acoustics for the side wall or in the platform. Any help would be great.
