Layout, with back wall as reference:
-partial rectangle 18.5 ft by 13.5 ft, right side is open except for closet, bookcase and kitchen counter by soundstage
-viewing area is L shaped with back wall (primary) and left wall with a wood stove at the vertex. The hearth encroaches 5 ft 8 in on either side of the vertex.
-soundstage 6.5 ft on center (doors left and right)
-ceiling is vaulted; left side 7.5 ft and peak at the partial wll 10 ft
Today, I just finished gutting the room. We are looking at open trusses and stud walls. For the surrounds I bought RC65i rear and RC80i side and Monster XPHP-CI cable. These are the only puchases made toward the 50 in Plasma screen butt-kicking system HT system.
How far from the wall edges should the rear speakers be mounted? Is the convention to target the prime area, (rear couch) and let the rest of the sounds fall where they may?
Should the sides, RC80I (ceiling) be off the right and left shoulders of the prime area? Should I angle speaker near the peak to offset the slope of the ceiling?
Should I cheat the rears or sides to more envelop the left side?
The rest of the system:
I plan to buy a Denon AVR 985S.
What Polk towers, center and sub are timber matched for a complemented system?
Am I making a fundamental mistake by not buying the components and testing before installation?
For my education and out of respect for your experience, I have read the 40+ page Polk handbook, read dozens of threads, visited dozens of websites. With all the details, I am one step from turning into a blithering idiot.
