Also, has anyone experienced this receiver setting the crossover for the main L and R speakers a bit high after Audessey setup? Per Audessey FAQ, it is the receiver, and not Audessey that sets the crossover. My speakers are rated to go down to 80 HZ, and Denon sets them to 200. I even got a replacement pair from the manufacturer.
On a separate note, per a few other posts in this thread, yes, the bass does sound overly boomy at times (fixed by turning the volume knob on the sub down after Audessey calibration).
