I'm putting this thread here rather than in one of the topic-specific forums, because I realize that the shape of the room will affect lots of things, from viewing angles, to acoustics, to furniture, to who-knows-what. The HT will go into a room 12 feet deep by 25 feet wide. Windows at one end and French doors at the other, so I can't put the TV at one end or the other. I'm OK with buying a big honking HDTV plasma to go in the middle of the 25-foot wall, if that's the only solution to the viewing angle problem. (hey, honey, we have NO CHOICE but to buy a plasma TV.... ) But if there's a cheaper/better solution, I'd like to hear it. Do the Samsung DLP units have the same viewing-angle limitations as conventional RP models? Acoustics: The room has a 7-foot ceiling. My wife insists on hardwood floors. Potentially, I can set speakers 25 feet apart...but is that wise? With the audience sitting in a spread-out manner, that's going to pose a challenge to make the sound "right" for everyone, won't it? How do you solve that problem? At what point do speaker cables get so long that the resistance piles up and sound quality degrades? What other sorts of challenges am I facing that the "normal" HT doesn't have to solve? Thanks in advance!
