MiniDSP 4x10 installed crossed at 250 and 1600 with 12db slopes. Mid/high down 11db for basic matching by ear.
Much better sound right off the bat. Weird phasing distortion is gone.
I ended up with an Outlaw Audio 7075 (7x75w) using just two channels for the mid/high and two Outlaw 2200 (200w)monos for the lows.
More later!

Please send me the passive crossovers and let me go over them for you. Even though you've gone digital/active, I'd like the passive setup to work for you too. Sorry for the inconvenience. I hope it has been a fun ride, and that the speakers sound good to you.

Have you ever heard the 7pi before your build? If not I suggest that you get the crossovers fixed by Wayne so you have a reference to compare with your current solution.

No I have not. I do have some very talented people at my disposal and pretty good ears though!
After playing with MiniDSP I can't imagine going back to passive. I just installed a pair of Nolte Audio 4X10" (per pair)175Lbs subs and I now have BASS!

...but you've yet to hear the passive set up properly, so maybe you would prefer it to the DSP. In any event, since you're not using the passives, send them on to Wayne.

Success!
John Nolte of Nolte Audio came over and set up the MiniDSP crossover driver by driver. He used the same XO points as WP and measured and set thing up from there.
Spent all day tweeking, went out to dinner then sat down and listened for a while.
These are indeed very nice speakers.
Because of the design of the subs, we had to lay them down on the front wall. They don't seem to do anything bad in that position. The sealed subs are flat to 24Hz and make crazy amounts of bass.
We have not done any EQ at all and could walk away right now and be 100% satisfied.

I measured the distance between voice coils between the subs and the the drivers in the 7Pi cornerhorns and added delay accordingly. The main speakers were 4.xx ms away. Amazing difference! The subs disappeared and I can no longer pinpoint the mid and high drivers with my ears. I now have stereo bass and very nice resolution on the mid/top!

Very nice speakers indeed.

Very good. Glad they're sounding good to you now. Thanks for reporting back!

I just bought a pair of NOS JBL 2012H midrange speakers off of ebay!475.00 for the pair. I have been looking for two years.
We will see how that goes. More later!
