Sorry, I missed the replys.
It's not a home theater setup, but the room acoustics are okay. Carpets and upholstered sofas and it's not a square box. No echo from clapping and conversations sound normal. I have Audessey EQ and volume enabled. Biggest clue for me is that until I got the 2809 the speech from the samsung TV was clearer than from the speakers. Now I'd say it's about equal, but not impressive in any way. Shouldn't it be?
