Wayne, I went way back in the archives, found a previous post about this.  You had mentioned that a crossover can be asymetrical, and other techniques used to flatten the response curve, etc.  I will play with this active xover, see what kind of results I get.The horn I will trying is good down to 700 hz, so that's covered.
What I wanted to do was get away from the 2000 hz peak on the woofer somewhat.  I may just go on and use passive xover components.
