Please Suggest An Electronic Crossover


Speakers:  Infinity Kappa 9

Preamp:   Audio Research Reference 3

I’m looking to find an external crossover to add to my system.  Preferably a pre-owned unit…will consider new unit.

Would like to limit to $1k…but will go to 2k for the right unit.

As the OP i asking for recommendations , I feel free to make one without being accused of generating “spam.”
I have had excellent luck with a vacuum tube electronic crossover custom built for my system by  Marchand Electronics.  I biamped my Magnepans, completely eliminating the factory crossovers.  Results have very satisfying.
If you mean an active crossover, no I cannot recommend one. I have not heard a single one that sounded good. A couple I tried to upgrade with boutique components; I could improve them, but never to a satisfactionary level


They are good enough for pro audio, but they are not good enough for hifi. I’m sure a genuine hifi quality unit could be manufactured, but that wouldn’t be cheap.

I just about listened to them all tube SS (analog) even a Deqx (digital domain, sterile is the word that come to mind).

The very best I found was the newer discrete SS Nelson Pass "First Watt B4" active analog xover only a few were made, they were $1500 but do come up used though. (some idiots ask a fortune though tell’m where to go)

Hello Mitch4T!  If you want it with fixed frequencies, use one of the units from miniDSP.  If you want to play around with the crossover points get a DBX unit (like the 223 - different kinds of connectors on different units) will let you have fun trying different crossover points. I have (and am using) 4 miniDSP and 3 DBXers. Great stuff!
Enjoy, Boomer Bill
