I explained to Dennis that I am hearing some harshness from the Revels in this particular room, it is most noticeable at higher volumes. He suggested trying to reduce the 3000hz to 5000hz a few db if I could. I tried that with limited success, I think Audyssey handles higher frequencies poorly. Anyways I think the issue I am having in this room can’t be fixed with Audyssey, although I did eliminate some of the harness I was hearing.
My options are limited, with the optimal solution being to sell the Revels. I am not willing to put a larger carpet and cover the floor to ceiling windows with heavy curtains.
What I did learn from all this is that the Revel F226be has some mid-treble peak on axis, and shelved up response from 3000 to 7000 kHz. Interestingly I did not hear any of this or any harshness in any other room.
