Denon AVR-S700W - No mid-bass voltage coming from the sub channel

Audio theory, Setup and Chat - www.avsforum.com
I had been wondering if it might have been sub placement, but I checked the voltage from 10hz to 160z with sine waves and it starts falling off sharply at ~25hz. Could I have something severely messed up in Audyssey, or is the AVR and Audyssey even capable of what we're seeing here. Which is effectively a LPF @ 35hz.

Here is roughly where the voltage line SHOULD be, showing the LPF being at 80hz... the -3db point.(2 volts / sqrt2 = 1.414 volts)

Here is a "sub only" sweep which also shows the premature, abrupt decline in output.
