Wanted - Active 2 / 3 way crossover

Looking for an adjustable 2 / 3 way active crossover to play with some ARC 101 and 050 speakers. I have an Audio Synthesis non-adjustable one, but I would like to try and adjustable one.

I have a stereo 3-way fully adjustable for phase, level, crossover points, slope etc.
Usually you will find ones with 4 channels, giving you stereo 2 way OR mono 3 way (with one channel unused.)
This one is a bit of a rarer beast.
It is NEW, unmarked and unused, but no box.
It’s a slender 1U studio rack mount type.
If you’re interested, let me know.
I can give you more details in a couple of days.
Let me know if you’re interested. I reckon £85 plus £10 insured postage should do it.
Cheers, David
