I can't give you guys any torsional specs, but I can tell you what it's like 
to play an XB-2 through a 422. The 422 is a 4-channel solid-state model with 
the Rotosonic deal. It took me about a week to blow out the 6x9 with the 
XB-2 connected directly through the 11-pin. And it's nearly impossible to 
get in there and replace it. You have to cut apart the glued Masonite drum. 
A pain in the drain. Anyway, it didn't sound great when it worked. My advice 
is don't bother.

small bearing type deal that will pass the signal through to the speaker. So
there is not much torsional imbalance, if any.  My question is how does the
6 x 8 spinning in the offset drum interact sonically with the fixed downward
pointing 15" woofer???...dallas
