Vandersteen 4

I've acquired a pair of Vandersteen 4's with the WX-4 "Electronic Bass Crossover". Could someone with experience with these please advise me on the wiring ?

There are 3 connections on the back of the speaker, "Tweeter and Mid-Range", "Mid-bass" and "Woofer", plus a switch that selects either full 'Full-Range' and 'Bi-Amp'.

The crossover has "R&L INPUT", "R&L HF OUT", and "R-STEREO-L LF OUT". There are holes for "R-MONO-L LF OUT" but they are blanked off.

My understanding is that the crossover inputs are fed from the power amp outputs, but since the WX-4 crossover only has RCA ins and outs, it gave me pause. It's kind of hard to mate RCA connectors with the mongo cables in use these days :>) I just want to make sure before applying power!

Thanks

By the way, it is an active crossover and with an AC power cord.

I'm pretty sure the WX-4 goes between the preamp and amps. The R&L INPUT would be from the preamps outputs. The R&L HF OUT would go to the high frequency amplifier and the
R-STEREO-L LF OUT would go to the low frequency amp.

The speaker itself connects with speaker wire from each amp.

Yikes, thanks!

That would explain the RCA ins and outs then.

On the Vandersteen FAQ page Richard Vandersteen writes that that the Model 4s have to be be bi-amped, implying Mofimadness is indeed correct on the WX-4 wiring before the power amp.

I'm still not sure what the Full Range/Bi-Amp switch is for in that case.
