Alan I am in the process of converting my speaker to use an active crossover. I have experimented a bit with a borrowed DEQX, and I can tell you that you DEFINITELY do not want this thing in your signal path. So, I plan to use the DEQX to help me find my settings. After that I will "hard wire" the crossover to the mids and highs with a Marchand, and use the DEQX for the woofer and subwoofer.
I do not wish to scare you, but with your horns you have a few considerations you may want to implement in your crossover.
1. Slope. I have found that steeper slopes sound better. Not true in a passive crossover, because you need a lot of components in the signal path to get a steep slope.
2. Phase and time alignment. I was surprised how much of a difference this makes. The sound suddenly becomes so much more coherent when it is properly time aligned. You may be able to do this by physically arranging the drivers, but it can be hard to do this (and achieve an aesthetically satisfactory result) with a horn.
3. Equalization. Ideally you only want to equalize below 200Hz and not above, because all equalizers introduce colorations of their own. You may want to consider some notch filters to take out some peaks in the F/R curve.
The success of your system will be VERY dependent on how succesfully you implement your crossover. More than anything else. A badly designed crossover with good drivers, amps, etc. will never sound good. I wish you the best of luck :)

Keith
