subwoofer amp with crossover/phase control

Hi Zipost,
That's a tough one. I don't know of any outside of car audio.

Buying a mono amp and a crossover is going to be more likely.

Do you need variable phase, or just polarity?

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.
