Hi everyone - my search for information on Speakon wiring and passive
cross overs continues. Part of the problem is that the Neutrik spec
doesnt cover this - it does cover bi-amping etc.

Anyway, the Peavey rep I spoke to said that most of their speakers now
have a separate crossover output speakon set 1+/1- @ 140hz high pass.

The EV technical support had a different approach - the Eliminator subs
only use the passive crossover for that sub and the original signal is
passed on +1/-1.

All of this seems much more sensible than the current mess on some
of the older systems where different signals are sent on channel 1 and
channel 2 and the assignment of low pass and high seem to be manufacturer dependent. In the meantime, if you buy subs with passive crossovers and
speakon connections it might be worthwhile glancing at the circuit diagrams/specs.

Even if you bi-amp you're not safe.

I've also seen at least one sub expecting a bi-amped input on +2/-2 (this
is important as some amps only provide a signal on +1/-1). Again, hopefully
this will get phased out.

The whole point behind the speakon design was to avoid end users having to
cross wire etc 8(

Hope this helps a little,
Chris.

PS having the bi-amped input to the sub on channel 2 does make some
sense as that manufacturer argues all low pass should be on +2/-2
and all high pass should be on +1/-1 all of the time. So you dont
pass the sub-signal to tops and vice versa.

(Thought I'd add that for the sake of fairness)

I do feel you are confusing your self a little here


all the spekers i have ever seen with speakon connectors take input on 1+/1-

even if there is an internal crossover is still ok to put a signal in from an amp thats part of an active biamp setup, you just lose some of the sound if you get the cross over points wrong.


the probelms come into play when you try to daisy chain moer than one speaker from one output of the amp, here you have to watch the load value and make sure your amp can handle the lower ohm value...

and if daisy chaining from a sub make sure you know what sort of signal you are getting.


it is now common practice on most major speaker cabbinets to have 2 speakon connectors on the back with 1+/1- directly connected to the second socket 1+/1- for the linking of a second set of speakers....
