Hi Ken,
You likely know what I'm going to say: turn off Audyssey!
That reverb effect sounds really gross. I have no idea why that's happening.
Honestly, with wide-range neutral, linear speakers like Axioms, Audyssey will only screw things up. Neither I, nor Ian, nor Andrew (Welker)use it. If you want to play with it, go ahead (when your wife isn't around). If you had crappy speakers with non-linear response, of which there are many, I'd say, sure, Audyssey may help quite a lot. But with Axioms, you just don't need it.
I admit there may be some utility to Audyssey for the bass octaves, but otherwise, it's error-prone, as you've discovered.
Regards,
Alan
