I suspect that the frequency adjustments on the CX3400 aren't very precise. And, while I've never had the cover off my CX3400 to check, tuning is probably done by sticking VCAs inside state-variable filters. VCAs have a hard time doing variable gain without introducing distortion; there are some very good ones now. Still, I suspect that filters made with fixed R and C elements and conventional op-amps will be better. But, the CX3400 was a steal for all the features it crammed into one box, and I had no problems when I was using it in my party setup. But, I've replaced it with something much better...
The Behringer DCX2496. It's arguably more of a "speaker management system" than a mere crossover. There's limiters, EQ, delays, and some features I've been unable to figure out a use for. It accepts digital or analog inputs. You can program it from a PC through a serial cable, maybe the easiest way to get started, but the front-panel LCD is fine with practice. Plenty of audiophiles like it, although some modify the heck out of it.
