I've now watched Master And Commander, Deathly Hallows Part 1, a couple of sitcoms, and the BCS game last night.
I started by having to turn my surrounds (Polk R15s) down about 4-5 db from where Audyssey set them, which I thought was weird. The Polks are much more efficient speakers, but I thought Audyssey would be able to take care of the level differences. Apparently not. I struggled for a while trying to find a good balance but wasn't able to. It seems the Polks either overpower the front speakers or are all but inaudible. I suspect another pair of SuperZeroes may solve this
Across the front, there's a certain tightness to the sound when watching movies I can't quite put my finger on. When I switch back to music they sound really, really good. They sound perfectly normal watching football and sitcoms too. I'm not quite sure what's going on. Maybe I should go run Audyssey again.
