ok so am now using only 2 terminal leads to the speaker and am internally jumping the voice coils. seems to be back in phase.... so freaking weird! thanks for the advice! i talked to AQ today and they were absolutely baffled as well

If your suspension is extremely saggy and the coil exits the gap rearward then the driver can leap out of the gap rearward and then move with a rearward bias -- meaning the movement can be centered around a point that is behind center... but it will still move both ways.

A lot of people miss this but it's very true.

the sub literally looked as if it had ZERO outward excursion... every time the bass hit the cone was being ****** in so far that the foam surround was being folded almost together in multiple areas equally surrounding the sub... if any of you wish - go to one of your subs and push the cone into the basket as far as you can until you make the foam surround fold if you can and you'll see what I'm talking about
