Rick: The active crossover in my JL-1s which splits the bass and treble signals is a Marchand product. About to be upgraded and tweaked by that "someone" you refer to. :^) Uses high quality parts, although not a cost-no-object design (although I believe Marchand has more esoteric products available than the boards in my crossovers). Marchand is a well-known name in the active crossover area.
