Or perhaps my ears are screwed.

My room measurement is 15'W x 16'L x 15'Ceiling.
Maybe it's the 15 ft ceiling.
My experience with Room Corrections has not been great.
First, it was the Harman Receiver, and that was TERRIBLE.
Then when I tried Audyssey twice on the 5308 and once with the AVP-A1, I couldn't even tell a difference.
If I try Audyssey again with the Orions and cannot tell the difference again, then that will be the last straw!
BTW, the Orions should be here in 2 weeks.
