We need others (with non-Denon amps) to try this. Maybe it's our amps.

Even if there is a problem with the Denon LFE cross-over circuit and it's letting all the lows through to the M80s, I am totally shocked that the M80s would even respond at 10 Hz.

By the way, as I've posted before, I, like Randy, have the M80s set to small and have only LFE set (not LFE + main). Randy, on my Denon 2105 I have the "LFE + main" option even when I set my fronts to small.

Why is this happening???
