CheYC et all,
What confuses me is that the L880s are spec'd down to 30 Hz, yet the crossover set by the avr at 150 Hz is way too high IMHO. One more idea for a test to CheYC to rule out any defect of the Fronts would be to swap the front L/Rs with the surround L810s and run Audyssey again. Check whether this extra high c/o follows the L880s or not. Please note, both speakers need to be swapped coz the crossovers are always set for speaker pairs.
This is a good idea. Currently the crossover for the 810s are setting to 120 hz, which even though their spec is 60-40kHz, seems reasonable to me. Those fronts though should definitely be lower though... I can't imagine anything being wrong with my speakers at this point, I've confirmed every driver is pushing and I've heard 63 Hz frequencies coming out of them as well as confirmed by Disney WOW, but it's worth a shot.
kbarnes, LPF is set to 120 hz.
I'm going to do some reading tonight on REW and hopefully that'll tell me whats going on here.
