I'd like to put somewhat of a home theater setup (5.1) in a rather large family room. We presently have an older model Harmon Kardon a/v receiver (will have to add model # later on as can't remember it). The room is 17' long, 23' wide and 20' high. The tv is located in a corner of the room (adjacent to windows and fireplace). The other 2 "walls" of the room are "open" to a hallway and a kitchen (separated by square columns). We don't want anything expensive in the way of speakers - already have a media room upstairs with that set up. I'd like to get the speaker set for $1k or less but would be open to more expensive sets if it really sounds that great when I listen to it. Also, because of the room set-up, the speakers would have to be either wall-mounted satellites or small bookshelf types (sort of prefer satellites). I realize the room is large and not the best for sound but just want something fairly decent. Does anyone have suggestions?
