Active external crossover


Does anyone know of a good active external crossover?

I know Krell used to make a good one 30 years ago.

I’d like to bi- amp, but have no good active external crossover any more.

the Pass brand electronic crossover is a very good one.

Another is a customized Bryston 10B. We had one made by Bryston, to cover just the mids. 1.25khz to about 4khz, in 11 steps, with the standard 6-12-18 db slope potentials for each, and level controls for the high.

Bryston will customize them on demand.

The most ’high end’ perfectionist oriented one is the Pass unit. (XVR-1)

I’ve tried some of the best digital units that exist, modified them all to improve them in any way I can and could..but still..a no show. They all destroy signal fidelity more than they aid it. This.. I say...when listening via my perfectionist oriented and distortion sensitive ear, --IMO and IME.

The measurements are not the sound quality. The map is not the territory.

Stop making that mistake, I say to detractors who think that DSP is the cat’s meow for crossovers.

If what they like to say about DSP were true, then all the world’s finest loudspeaker manufacturers would have switched all their best $25k, $50k, $100k, $200k etc speakers..to using active DSP crossovers.

Note they have not done so.

Some ideas/crossovers, available from these guys:      https://www.allegrosound.com/4sale_crossovers.html                     Keep in mind; the pro stuff is typically XLR only, so: adapters, if you’re single-ended.

I wouldn't go digital for doing xovers, I tried the Mini DSP 2x4 hd and the Deqx both which had sad sounding dac's (but they are great fiddling/time wasting tools), not worth in any way taking out what my MSB Discrete R2R sounds like when doing the D to A by it self. 
The best active xover is still analogue, 24db for doing  xover'ing and yes the Pass F5 was a nice one but not 24db I think just 12 or 18?, there are a few others like the Marchand SS ones,(I don't go much for the tube ones). You can get cheap Behringers but they need mods to make them good.

I built my own 2 or 3 way 24db like this and used very good opamps and power supplies.
