FWIW: the acoustics ought to be weird in my living room but are strangely okay. 14' x 17' room with 8-foot ceilings and lots of windows (and wood floors), but also overstuffed furniture, area rugs, curtains, and a brick fireplace (and painted mottled drywall). Because of the configuration of the room, the main and surround speakers, all in-wall, have to be about 6 feet off the floor, and they're confined to an 8- x 17' section of the room away from the windows. Somehow it works, although because they're mounted so high, the sweet spot is standing just
behind the couch rather than sitting on it (!).
Anyway, the overheads are also relatively low, but that doesn't seem to be a problem. I was going to go with some slightly pricey Episodes, but as I was hemming and hawing over whether I could swing four of them, my installer convinced me to go with a
much cheaper model--$160 a pair--which he said the company hawks as "contractor-grade" but which sound just as good. I like them a lot. (Episode
