I have been struggling with this issue for a number of weeks.
Before you open the layout below, here are the details.
I have a 15 x 20 room. $%^& fireplace is dead center on the short wall and the opposite wall is totally open to the kitchen area.
Along the other other walls are numerous windows, doors and a large opening into the living room.
We are having the current mantle removed and a custom built hearth/cabinet built that will span the entire 15 length of the room. The cabinets will house the HT compnents and the cabinet in the corner is going to house a forward firing sub (Velodyne DD12).
The 50" Plasma (not purchased yet but likely to be a Pio 1120 or 1130 if I wait) is going to be mounted on an articulated arm so that when not in use, I can place against the wall and when in use can be swung out to bridge the corner (see attached). Im still doing the math to figure out if there is an arm that can do this.
I have no floor space for towers so all 7 speakers (7.1) need to be mouted off the floor. The L&R speaker will be mounted on the wall and the center (not shown on drawing) is going to be mounted across the corner. The sides are going to be mounted immedately adjacent to the two couches at the highest part of the wall. The two rears are going to be ceiling mounted (most likely in the ceiling) since I cant seem to get a symetrical layoyut otherwise.
For whatever its worth, I was looking at Magnepans for the LCR speakers since the the L&R can be swung out to parrallel the TV and swung flush when not in use. All speakers are still under evaluation.
I regard to my speakers, my biggest problem is finding a single brand that can provide all the different types (wall mount, ceiling mount, etc) that I need.
Any input into my layout (and speakers $2-3K) would be greatly appreciated. The cabinet is getting installed in a couple weeks which give me that much time to run wires for the speakers.
