Speaker Placement


OK, guys- I've spent several hours combing through theories, threads and treatises and am still at ground zero to determine initial speaker placement. Got a a pair of Maggie 12's with a powered sub going into a 16 1/2 by 22 1/2 room. The ceiling is coffered from 8 feet at the walls to 10 feet. (slope is 6 in 12) Floor is carpeted, walls and ceiling are sheetrock.

So far, I've heard it all- close to the wall, far from the wall, close to the side walls, further from the side walls, sit closer, sit farther etc, etc, etc.

Any planar placement formulas/experience out there that will get me started?

Thanks
Jim

Hey Jimbo, I had Maggie IIIAs for 14 years and by trial and error I came up with the following:
-tweeters on the inside
-44in from the back wall
-tweeters 56in apart
-toe in panels toward center listening spot

Start with these measurements and then tweak them an inch at a time to your preference. Hope this helps.
I have not had planars before, but here's what works best for me...

Try the rule of thirds, pull them out about a third of the way into the room, and about one third of the way away from the side walls. That is a place to start. Then use your ears. There are no formulas that are better than your ears because they can't take into account your room and furnishings. That's how I've had the best luck.
FWIW the last time i set up planers i had them in a room 13.5x19.5 firing down the length of the room with the center of the panel about 2.5 ft from the side wall and the speaker about 4.5 ft from the back wall with the panel turned inward half way toward the listening position. the listening position was mid way between the two speakers 4.5 ft out from the back wall. the sub was against the wall between the two speakers. caveat - this ain't a science, be prepared to do a lot of moving of the speakers. also i found it helped to have something behind the speakers that acted as a diffuser. good luck.
