Thanks
I thought that might be the case.
The mains, the primary xover (The DEQX, or Behr for that matter) correct for pase of the units downstream. I do have a 2nd standard ICBM, that I use for rears/side that go to a 2nd sub in the rear. I was thinking of using that for the fianl xover, with sides (mmgs) going into the 1st maggie ICBM, and rears into the 2nd standard, with output of mains from 1st going into the mains into 2nd, main out to bass panel and sub out in stereo to stereo subs...
