I might have to take advantage of the AVS forum / Dennis Erskine service available. Just prepping for the build has turned more costly than expected so I'm trying to keep costs down. With that said, I can only imagine the number of surprise expenses I'll encounter when I start it.
, the Onkyo 3008 I ordered should handle the two subs.
One concern is a lot of the results we read about are based on rectangle rooms. My fear is planning so much only to find out it really didn't matter because of the variety of items in the room or the non-perfect rectangle.
Regardless, I pushed forward with trying to manipulate the room to get a second sub close to the middle of the back of the room. I came pretty close so. About 10" off center which I doubt will make much difference. Another option is to build the sub into the counter behind the back row. I'm assuming that would be too close?
I ended up bumping out a little niche for the sub into the foyer to the theater. Which will force me to double stud wall, DD/GG the foyer as well. One thought is to put a rotating rack above the Sub just above the chair rail lines. The sub would be contained and not viewable from the foyer. I could then build a grill using trim that matches the room for the sound to travel out. I realize Subs are not as directional as speakers, so hopefully this is fine.
I have room in the theater for a rack already so I'm not sure I want to move it out of the theater. It would make it a little easier if it was in the theater for wiring. And really I'm not sure what else I would put there. I'm not sure how much noise would be generated by any of the components I plan on putting in there.
My other concern is if I place the components in the foyer, then I'd probably also have to consider a vent and return in there in addition to the theater. Just opens more cans of worms as far as sound proofing goes. Without the rack in there, I don't think I'd have to worry about it. I could instead use that space as a Bass trap or just put a counter top on it to dress up the foyer.
I also played around with other ideas of trying to squeeze the sub into the existing room. Here are some of those concepts. I just thought if I went this route, it would either force me to eliminate the back bar and seating. It starts to get pretty tight so I've been trying to leave that space open.
