Recommendations for electronic crossover.


I am bi-amping my B&W 804 matrix speakers with a 50 watt per channel tube amp for the top and a 200 watt SS for the woofer. Any suggestions for reasonable priced crossover? I have been told Merchand (?) makes a good one.

Thanks!

And I thought listening

Na, you already proved you can’t do that with this statement.
Every one of us preferred the sound of the bridged configuration, with some describing the sound as now being "more hifi"
The "can’t see the forest for the trees" was the technical aspect of what you know, and what happens to a stereo amp when it’s bridged, all you gain is watts EVERYTHING else takes a hit.
Bridging makes what was maybe a good amp, almost a P.A. amp.
Bridging has nothing except more wattage over leaving the amp as stereo, you've been told now not just by me.  
Not in the least, still fact with Class-D's today.
Sorry,  Not in the least, still fact with bridged today.

In general Bridged Amps
Pros=
More watts.

Cons=
Worse damping factor
Higher output impedance (has relevance to damping factor)
Lower stability (especially into low impedance’s)
Current ability is reduced (especially into low impedance’s)
Higher distortion.
It's always has been the same.

Sounds to me mostly like theoretically-based conjecture. Have you listened to bridged configurations to form an opinion this way?
Yes, and if you search you’ll find all the info I’ve heard/measured and found on it.
Like I said above , bridging amps makes what could be a good stereo amp, lean towards becoming a mono PA amp. As many parameters take a hit, not just the ones I’ve mentioned above.

This statement says it all.
A really good amp should sound big, tight and wash over you with dynamics and detail that don't sound like it's coming from any of the the speakers drivers, and have a sound stage you feel you can get up and walk into.

Don’t go digital to me it only led to sterility no matter what I tried. And I lost the sound of my favorite dac for whatever rubbish dac is in the digital dsp/xovers ones.

If you want the best analog domain xover that’s discrete and that doesn’t use opamps, get a Nelson Pass designed First Watt B4, probably have to find a used one

Or what I would do with those speakers is to go horizontal Bi-amping with the apms you have as the B&W internal xovers are of very high quality and well sorted.
Or with something like a nice Pass Labs Class-A XA30.5 (amp1) on the mids and highs and a cheap Class-D (amp2) on the bass

Just put a $49 Schiit Sys passive on the input of louder amp to even out the gains, and drive all that from your preamp.

Cheers George
Not my experience. Recently went all-active with my existing Xilica digital cross-over, and it’s a bliss.
Each to his own, on that.

To each their own, but bridging is seriously underrated in hifi
That’s because all you get is more wattage, everything else takes a hit, especially current drive into lower impedance’s and stability, distortions. It almost makes what was a good amp into a PA amp.
