After you ran MCACC, did you check the Standing Wave correction data to see if the [SUB] frequency was actually targeting a frequency that your sub reproduces?
The AVR appears, at best, to target one standing wave in the subwoofer range. So it would hardly be expected to do what a BFD can do.
MCACC does not EQ the sub. Pioneer explicitely states in the manual that MCACC does not EQ the sub.
From page 42 of the 92/94 manual:
The nine band Acoustic Calibration EQ (either Pro or standard) doesn't affect the sub channel at all.
But clearly there is an adjustment to something called [SUB] in the Standing Wave correction
algorithm (which correction, btw, was not a feature of the first generation or two of Pioneer Elite AVRs)
Pardoxicallly, the target frequency of the [SUB] adjustment is sometimes well above a typical subwoofer frequency (e.g. >125 Hz).
The two questions thus would be
1) is Standing Wave correction considered to be part of 'MCACC'
2) what does the [SUB] adjustment mean?
