    Situation is that I have a 3 way stereo active line level crossover that does not sum the low band for a mono sub. I could try using a Y for the low outs and feed that summed signal to the BFD then to the sub amp, but I suspect that is a bad idea without a buffer circuit. Could I feed both channels to the BFD, link the filters, then "Y" the BFD outputs together into one for the sub amp ?

    If I were in your shoes and have one sub, I'd use both channels of the BFD, link the 2 BFD's channels as a stereo pair and Y-sum them at the outs of the BFD.

    Using 2 independant stereo bfd channels to go into one sub can be pretty messy. We could change one channel, but the other unchanged channel may have unpredictable and perhaps irritating inconsistencies while correct room modes.

    Just my thoughts.

    Brian,
    I agree with Ming. Coupling the two BFD channels and Y-ing the outputs seems the most logical solution.

    It may be almost as simple to make a buffer... any old opamp will do.
