Maggie 20.1 and Marchand XM-44

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

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

Hi Salmonsc:

Currently, I am using the ARC VT100 MKII on the midrange/treble and the Kenwood L07M monos on the bass panels.

I am getting tons of bass, dynamics with >100dB SPL at my listening position. The combo is an excellent match: the Kenwood are very smooth which helps in blending with the ARC. Of course, many audiophiles will say that the ARC VT 100 is not powerful enough to extract the best performance form the 20.1s. But I am very happy with the results. The sound so far is incredibly musical, robust, pristine, panoramic, dynamic with tremendous bass impact and definition.
