Alright Ken!!;

In one line you seem to have summed up the entire question-well, at least the one I had, anyway.

My problem was "that" part of the signal below 80hz that was sent to the sub along with the .1, but which was still audible and directional! (That and the fact that some rear channel speakers I've used have a tendency to "hisss" rather than "roar") Heck! for the price of two trips to Mc Donalds with the kids I can buy a couple of subs(NO, not Subways)but add the subs to my M3s(or QS8s)and have full range speakers out back and have the best of both worlds!!
They don't have to be real high quality subs, cause for surround, who cares-the important attack will still be produced by the M3s or QS8s.

Sounds like a real hoot to me!
Or am I missing something here, guys?
Rich.
