Great room 24' x 19' w12ft ceilings. This is on an open floor plan with dining room and kitchen joining. I need a sub,bookshelf speakers, center, and ceiling speakers....I know free standing rears would be better, I can't have clutter with the open floor plan and the wire is already run for the ceilings. I've never had a theater system and the bose demo sounds great to me at Sams, so I don't need the best thing ever. A smaller sub would be better, I've already got a pioneer 821, and this system would be used mostly for t.v.
