subwoofer amp with crossover/phase control

Hi zipost,
Without getting too technical, slope affects phase, so you can get away with changing the slope instead.

How about a miniDSP crossover then? You can adjust the group delay, phase and EQ all in one.

Then you just need an amp you like.

Best,

parts express sells a decent one - it's actually used in the "Storm" subwoofer array system.

There are two things I would pay someone to help me with:
1) properly setting up my JL Audio F112 v2...I don't understand phase and slope.
2) setting up my speakers 

Check with Danny at GR Research he is the supplier of the amps that Rythmik uses for their subs.
