If you have the values for the thing, it should be cheap and easy to
build a copy.

I don't have values but I know there is a nasty rise between 2 and 4
Khz that needs to be tamed and want to crossover at around 400 Hz (to
start). The TAD crossover does so at ~ 600 Hz which is OK too. Been
thinking of buying filter software to try design of network, such as
that from ALK engineering. But thought if pro shop had one, I could
start there....Don

OK...those are good suggestions. I didn't think that TAD would publish
the crossover schematic but I will call and see.

Down the road, you might be interested to know where I am headed. I am
real interested in: DEQX Calibrated™ PDC-2.6 or 2.6P :- Digital
Calibration Processor and Crossover for Loudspeakers & Room Acoustics.
But that is for another time, years from now.

Call TAD. Get the service manual. Build the crossover.

If you decide you want something else, call Madisound and have them
design a crossover for you from the driver models.

ALK Engineering doesn't do filter design software for speakers. Speaker
crossovers are something of a specialist filter design area and not
suited to general purpose topologies.

I thought ALK filter design software offered is specifically for
crossover design. Maybe it is for microwave engineering which appears
to be another specialty of theirs. My assumption is because they redid
the Klipschorn crossovers, their filter software helped with this.

How do you expect people to repair anything if you don't publish a service
manual? All legitimate audio vendors will give you a service manual with
real schematics and often a verbal circuit description for the aid of service
folks. This is one of the serious differences between Manley or Orban and
guys like ART.

Quality equipment is designed to be repairable, and part of that repairability
includes making public the information needed to repair it.

I'd try a Rane AC-22 first. Cost you a hundred bucks on the used market
and it's not half bad. It can be upgraded to make it better sounding and
more reliable with a little work, but it's a good entry-level active
crossover.
