He called a lot of things right a long time ago.
350hz is certainly too low for your mid driver, and first order only makes it worse. Gross distortion at moderately low volume I would think.
Hard to believe you've only tried two first order crossovers. Do you have the calibrated mic that goes with the minidsp? Considering you built your mid horn and your bass bin I would think it a necessity. You don't have to get fancy and take them outside. You can do it in the room. It will help to know if you need EQ.
Generally the lower you go the steeper the slope must be. It's always possible to figure in the acoustic roll off like you are doing. The Marchand I mentioned can go as high as a 48db eighth order slope. That's a crossover that's doing something.
You should be in a measuring mode right now. OTOH a 24db slope at 500hz would work fine as a start.
If you ever want a passive crossover, then I would say check out ALK's site first.

Big speakers and little amps blew my mind!
