Behringer also has a couple models which I believe are analog, depending on whether one is attempting to bi-amp or tri-amp:

I have no idea if the quality of these crossovers for critical listening. They are in common use for sound support and don’t exhibit the same issues as some users have pointed out in the digital-based DCX-2496. Sometimes used CX3400 and CX2310 show up occasionally on the classified and auction web sites at pretty good prices.

I plan to experiment with a CX3400 for tri-amp use. If the concept works well, but the CX3400 sound quality isn’t quite as good as I was looking for, then a DIY circuit may be in order. The CX3400 has variable crossover points. If I change to a DIY circuit, I will have already established the target crossover points for a particular set of drivers in an enclosure.

While I don’t like unnecessary A/D/A conversions, if I’ve read the literature correctly, beyond just crossover use, the DCX-2496 has some limited additional functions that would allow a user to EQ a set of speakers for a specific room without the need for a separate unit that might use A/D/A conversion anyway. If I were going through an A/D/A process for the sake of some EQ, I might as well perform crossover functions while I’m at it. Behringer claims that the DCX-2496 uses the ‘ultra-high resolution CRYSTAL®/AKM® A/D & D/A converter’, which I know nothing specific about.

Similar to my planned use of a CX-3400, if one used a DCX-2496 during experimentation and evaluation and learned what kind of crossover points and voicing work well with your speakers in your environment, then that would establish a target for an all-analog DIY circuit build.

I highly recommend the site Altec mentions, Elliot Sound Products , and additionally Linkwitz Lab .

If you are the type that likes to learn about these things, good reading and references:
