External crossover Equalisers (HW)

External crossover

I want to bi-amp my Apogee Divas using an external electronic (analog) crossover.
( I don't want to use DSP and DON'T want to start a debate about digital vs analog crossovers!). In the hi fi world the Pass Labs XVR-1 is widely regarded as the best active electronic crossover. I'm just wondering if there are any from the pro world that I should be considering i.e. that aren't full of cheap and nasty op-amps - ?

Do you need FIR filtering...could you benefit from AES inputs ? Bi-tri-quad or Quint amp configuration ?

I need analog inputs, preferably balanced. I only need low and high pass filtering. Bi-amping capability a necessity, tri-amping capability would be nice.

Slightly customized Bryston crossovers have been the crossovers for PMC’s reference/large active speakers for a long while (though I’m not sure what is being used on the QB series)

In the hifi world, the most used device is the berhinger dcx2496 whatever the high end level of the rest of the installation.


In the pro world, you have Crossovers – Thomann UK

In my experience, most of these analog active crossovers (even in the case of the higher end units) do not offer the flexibility in setup needed to provide the drivers with the correct slopes/frequencies to keep phase relationship and overall magnitude response correct...

Hello,

Have you measurements to confirm your comments ?

Yes, that's one of the reasons the XVR-1 is highly regarded.

As for the DCX2496, it's cheap. I made a comment about cheap and nasty op amps in the opening post . . . .

Sorry, i didn't see that you judge the quality of a product by his monetary value as it should be in the audiophile world.

Well either you are wilfully misconstruing my comment or I was being too subtle for you. There's an awful lot of BS and overpriced hi fi gear and you have to be discerning about that. At the same time you get pro gear that's built to a price and that's achieved by using cheap components and sometimes ( but not always) cheap components introduce artefacts and other forms of distortion. Some op amps are notorious in that regard. Enter the DCX2496.
