I replaced a DBX 234XL 3-way stereo crossover with an Ashly XR2001. The difference between the two pieces is so pronounce I wanted to share this with other Forum members who are considering an active crossover.
The Ashly piece is considerably more expensive than the DBX, but well worth it.
What I found most noticeable was the "Response" control that allows you to contour the slope at each crossover point. This is very effective and really separated the two crossovers in my mind. For some reason the DBX x-over sucked the bass out of my system. The VU meters on my amp were pounding but there was very little bass coming out of the speakers. I still don't know were it went! That problem is gone with the Ashly x-over - the bass is back.
At the volume levels I listen to there is no discernable difference when the Ashly x-over is in or out of the configuration. I can't hear any color that it introduces.
I give the piece an A+. It excels in three ways: It has all the functionality I need. It doesn't color the sound. The crossover freqs/slopes are smooth, natural, and configurable.
Good riddance to the DBX x-over!
