What crossovers/EQs are available?

[Mike-48]

I've used stereo subs for 10 yrs now. At first, I used a TacT 2.2X to implement crossover, sub time alignment, and LF EQ. Then a mod shop stole my TacT. I replaced it with a Classé CP-800, and now I'm wondering about updating that, but there is not much high-end gear aimed at 4-channel systems (2 main, 2 sub), as far as I can see.

What I am looking for:

• Digital crossover between main and sub
• Adjustments for sub-main timing (distance) in each channel
• PEQ (automated or manual), mainly for f < 500 Hz or so (if auto, must be tweakable manually)
• Tilt or tone controls (digital) to adjust poor recordings
• A 4-channel DAC for mains and subs (but could use external DAC(s))
• Relatively straightforward to set up and operate

What I decided on was a Classé CP-800, which has most of the above, but lacks any sub-main timing adjustment. It also lacks a way to set sub levels -- one has to do that at the subs, which in my case (JL F112) means tweaking small, uncalibrated knobs. I use a Dayton Omni mic to get a starting point for manual LF corrections made with the CP-800's PEQ.

Here is some current gear that might work in such a system (my thoughts in parens). I'd appreciate comments if people have tried some of this, and also about what other pieces are good possibilities.

• DEQX Premate (Great DAC IME, but clanking relays on SR change; overly complex to set up)
• JL Audio CR-1 (crossover only, no EQ, which disqualifies it)
• Trinnov Amethyst (enticing if expensive)
• Lyngdorf gear (lacks manual tweaks to "Room Perfect" auto EQ)
• Classé (unreleased) CP-800 replacement
• Devialet ??? (don't know much about it)
• DSpeaker X4 (not yet released; appears to lack sub digital outs, AES3 ins; but otherwise a yes on features, at least)

An alternative would be JRiver and/or Acourate (or similar software) on a computer in the listening room. I have so far avoided having a computer there, as I think it would be a distraction. Also, Acourate corrections seem quite complex to get and keep running.

If anyone in Audio Aficionado is using such gear, it would be those in the subwoofer forum, so opinions, please!
