Nice build Fred. They are bigger than my Martin Logan ESLs, but your sub is much smaller. I have used the DEQ for room correction and it will do that. But I felt in the long run it did more harm to my acoustics than it did good. The Behringer electronic crossover (set for 24 db/oct at 45HZ 2 way) is another story. It is great for separating the sound to the subs and seems invisible.
I'm ok with the DEQX, but I'll probably build a passive crossover so I can use these speakers with any integrated amp or amp/preamp combination. They are very sensitive and the woofer array presents a 10 ohm nominal load, so it should be easily driven by an EL34 or KT88 tube amp.

Another less pricey option for dsp and bi-amping would be a mini DSP processor like this.
