In Reply to: RE: Problems getting a good 3-way x-over for home posted by Max Caliber on October 23, 2009 at 09:39:46
I forgot to mention in my earlier post that I also tried 2x Samson S3 3-way x-overs where one unit did ont function on one side and the other unit had a bad case hiss. Also I just added a photo of my system.

I'm currently using a DBX Studio, which is a DBX PA with different presets,.
I'm mainly using it for the XO funtions, however I also use the RTA and EQ, which works wonders to "fix" my terrible room. As far sound quality I'm very satisfied. However I haven't a/b any other active crossovers. I have used other EQ's Yamaha, Berhinger, etc and the DBX was by FAR the best. The Yamaha was a total shock...even in bypass it degraded the sound tremendously.

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.
