You will need four (4) modules not one to get the Marchand XM-44 up and running. You need a woofer LP (low pass) and a mid HP (high pass) for each of the two stereo channels - cost is $36 plus shipping.
Understand that the "recommendation" from Magnepan is only an approximation and was done because most commercial crossovers are not very flexible and are limited in their ability. The Marchand has the ability to be customized to just about any order, slope (Q value) and frequency and thus can be designed to match almost exactly the OEM crossover.
Here is a link to my spreadsheet which will simulates the OEM crossover. Ignore the mid LP and tweeter HP as you will not be triamping. The notation for the caps and resistors may differ from that used by Marchand but Phil will have no trouble with it. The spreadsheet is written for LibreCalc (part of the LibreOffice Suite) which is available for free. I do not support Microsoft.
If you have questions, please feel free to email me.
