This system fits the room nicely. Subwoofer is located behind the TV, near the rear wall. The room is quiet enough that you can hear your heartbeat. Standing waves are at a minimum, as the ceiling varies in height between 7 and 9 feet, and the long dimension of the room is broken by alcoves, and the short dimension is altered by books and CD racks at odd intervals.
The photo somewhat misrepresents the scope of the room, although even here it looks quite a bit larger than the tiny rooms that I see elsewhere holding very large speakers and piles of equipment.
I am quietly looking for another preamp so that I can move the old Meridian 541 upstairs.
Actually, the back side of the TV is covered with two inch sonex. This is "even better than nothing," in the sense that the sonex is better than just air.
If you look closely at the photo, there is a six inch steel I-beam right behind the TV, floor to ceiling that helps to hold up the ceiling, and the seven foot grand piano that is directly above this room.
There is about four feet between the I-beam and the rear wall, and that's where the subwoofer is located. It is oriented vertically, which gives measurably smoother response from 25Hz to 40Hz.
Have you tried moving the tv and equipment close to the back wall? Usually it doesn't help the soudstage/imaging to have such a large object in between the speakers. More free air in the middle might be a great "upgrade". You seem to have enough space behind the tv for that.
