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.

Hi Salmonc:

I am using a Marchand XM-126 to biamp my 20.1s. I recommend using the cross-over values which replicates the existing settings on the 20.1s:

Low Pass: 108 Hz, 18 dB/Octave (Butterworth)
High Pass: 330 Hz, 6 dB/Octave (Butterworth)

Experiment with the phase on the bass connections to the speaker

You will be pleasantly surprised at the dramatic improvements in all musical parameters due to biamping

Gmorris, Thanks - but are you sure about the high pass values? I was under the impression the correct values are:
106Hz 6dB Low Pass
250Hz 18dB High Pass

The values I used for the 20.1 x-over are listed in the user manual (Section: #18). However, a range of frequencies for LP and HP will work depending on your room, etc.

106Hz 6dB Low Pass
250Hz 18dB High Pass

Should be ok also

Thanks, I don't have the manual! Would you mind sharing what you are using for amplification? I am exploring my options for optimal biamping possibilities: watts/channel, tube vs SS, etc. I'd be interested in what worked for you.
