My dorm is looking to get surround sound for the big screen TV in the lounge. We're looking to spend about $500-ish on an HTiB. The room is pretty big (30x35 or so), but the area in front of the TV (ie - not taken up by the gaming tables) is about 12x15. So it's a pretty big space for an HTiB to handle. What would be a good HTiB to order for a space this big. (I know, normally people would say 'whatever sounds good to your ear', but there are 225 pairs of ears to satisfy, and I don't think I can drag them all over to Best Buy to test out speakers...) So what HTiB would YOU buy if you had $500?
