Rich,
In your journey, you should have experimented with different slopes of active crossover.
Can you give small write up on the slopes you are using and why?
Cogito,
I have experimented with different slopes for the DSP crossover. I do not use the original style filters that Magnepan developed since they are series mode filters. Triamping these with DSP is the way to go after the experiments with the MG10/QR's.
I like either 4th order or 8th order Linkwitz-Riley since they are 0 degrees at crossover. That is either an acoustical or electrical alignment depending on the driver. I typically use 8th order, as it allows the planers to have more power handling in band. I also high pass the planars and time align them to th subs. That solves the typical planar problem of sounding congested when trying to reproduce low frequency signals. Easy enough with the DSP.
