  Not sure you're aware, but a standard crossover doesn't have a 0.75mH coil on the woofer.....it's a 2.2mH coil.
  
  You're bi-amp reconfiguring switch setup looks good. I think I'd remove the 100 ohm resistor from across the woofer shunt capacitor though.
  
  Cheers,
  
  Dave.

    The newer - single order crosover uses a 2.2mH. the original MMG's used a second order as diagrammed

    That simplifies the switching configuration idea - the capacitor and it's draining resistor in the LP section can be omitted.
    Three most important things in Audio reproduction: Keep the noise levels low, the power high and the room diffuse.

      The subject line should read 2.2 mH not uH . Thank you to Davey for the correction.
      You are looking at Tazman's schematic. Check the official schematic and layout from Magnepan that was posted by Bob Cole

        It's 2.2 millihenry. Trust me.

          Absolutely 2.2 milliHenry A little lapse of the old noggin'. I will edit my post so future generations don't wonder why their woofers are running full range :)

          The drawing I got from Magnepan has a "write-o" or is just illegible.
