In Reply to: What amplifier do you use with your Magnepan .7 or LRS posted by nParbat on November 21, 2021 at 18:58:14:
The LRS are high passed at 100Hz/24dB using a Marchand XM46-AA passive line level crossover. Low pass to the REL T/7x LFE input is also at 100Hz/24dB.
Although the MK3 amps (rated at 60wpc) have plenty of power/current to drive the LRS full range beautifully, adding the XM46 did improve overall midrange clarity. I suppose this is mostly due to increased amplifier headroom. However, I also believe that, since the LRS bass/midrange/treble drivers share the same diphragm, removing low bass and reducing diaphragm motion from the LRS is also a contributor.
