My room size is about 4m X 5.5m with the height about 4m. Space is a premium in my living room as I plan to have a full 7.1 system with my Denon AVR 3801. I plan to mount the satellites on the walls at about 3m high. Will the size of the room drown the sub/sat system?. I watch mainly dvd movies. I heard good reviews about Mission FS2AV and was told they go well with Denon. What about Kef KHT 2005AV. May I know which is better?. Thanks !
