With Audio Weaver I typically use Linkwitz-Riley or Butterworth crossovers that can be selected as 1st order to 10th order rates. I have been using 8th order L-R for the crossover 2-way or 3-way for multiamp connections. High pass on the woofers for all uses as it removed out of band signals that can cause slapping of the diaphragm when to large to reproduce.

I have been using acoustical or electrical L-R 8th order crossovers to integrate subs to the Magnepan speakers at higher frequencies and using time delay on the mains if the subs are behind them. This removes more LF energy from the planars for lower distortion.

All the amps benefit from direct drive use since they only have to cover a smaller frequency range for each driver. Less stress on the amp and power supplies.

I use REW to measure the responses of the speaker and sub independently and see if there is a frequency that makes sense, but if the response is flat enough, then choose a frequency that is an octave above the speaker rolloff for the crossover point to the sub. The video demo uses that idea for integrating the LRS to the OB subs.
