I certainly agree with Argent: near rear wall and full range. In walls definitely compromise the sound. As for timber matching it is not as critical as the front three speakers, but there is no question that sticking to one brand will help create a seamless envelopment. I did say near the rear wall. I like the rear speakers about 45 degrees off from the central listening position. Now, I would recommend since this is a new construction that you wire for 8.1 surround. That means dipoles to the side and one central rear speaker. Who knows if this will ever be used--I find 5.1 channels is plenty to create a very satisfying theater experience--but as hardware and software progress there could be more channels. So even if you aren't going to hook up more speakers--wire it--it's cheap and if you ever decide to add speakers you'll be glad you did.
rear speaker placement for new theater
I am planning a media room about 17 by 27, with the projection tv along one of the short walls and the seating area about 12 feet away. As this is new construction, where should I put the surround speakers? On the rear wall? In the ceiling, slightly behind the seating area? Use dipoles on the side walls? Finally, can in-wall speakers really handle the dynamic range of the new surround protocalls? They seem really expensive for a small speaker without a box, and I don't see how they could perform as well as a small speaker with a properly designed cabinet. Thanks for the feedback.
