I crossed the tweeter over at 2k for a couple reasons.

1. It has much better dispersion at 2k than the 6.5" midwoofer so the combined system off axis response will be better than if the xover was placed higher.

2.The midwoofer has some roughness in its response above 3k so the lower xover point and steep 24db slope will mean these irregularities will be much reduced in level.

Yes the active units are pure analog.I knew the exact xover response (slope and frequency)I wanted to achieve so other than level adjustments the need for tweaking crossover points etc.was not a necessity.
Also I like the fact that the signal stays in the analog domain instead of being sent through different stages of A-D and D-A conversion.But I will add that the Behringers are absolutely wonderfull units for those who want to do alot of tweaking.

Im now mixing the bass below 80hz of the center channel with the LFE subs.
So you're extending the mids down to the 80hz point and then rolling off to the subs for a 3 way instead of a 4way?

Can you hear the difference if you crossover above 3500hz or well below it, in human voices? I guess if you match the dispersion, phase and have a flatish FR, you shouldn't be able to tell the difference, right? Life would be easier if I could live with a 2way (3way when the sub is taken into account)
