I've owned the Marchand and currently own the Pass XVR-1. The Pass is an awesome piece with tons of flexibility. While I don't have Maggies, I am running ML CLS IIZ's and the Pass has been great integrating those with my JL sub.
Maggie 20.1 and Marchand XM-44
I am thinking about moving to an active crossover for my Maggie 20.1's. The Marchand XM-44 seems to be a good fit but I'm not sure what frequencies to order. Is there anyone here that has experience with this particular pairing and what freq's and settings did you find that worked the best with these speaks. My inexperience with external crossovers has me totally in the dark here.
