Auto tuning behavior.
When I run the auto tune the 80PRS always sets my sub low pass to 80Hz 12db/octave, and my midwoofers high pass to 100Hz 12db/octave. It also set my subwoofer delay to 400cm (max distance) but my sub distance is only 150cm. I wonder if the 80PRS set this long distance trying to compensate for the phase issue caused by the 12db/octave xover?
After reading audiofrogs simple tuning guide I entered measured distances and changed the sub/mid xover to 24db/octave at 63/80Hz. This substantially increased the lowbass output.
So I advice anyone using the autotune and missing lowbass try something similar.
