Crossover at speaker level?

[icebear]

Hi

I'm presently using my Behringer DCX to split the signal between my dipole sub and my dipole fullrange. The fullrange dipole does not have to go trough the Behringer, cause I do not manipulate the signal in any way. So it's only for LP to the sub realy. I do have a autodelay in the beringer, to compensate the runtime tweeter/midrange to bass. I run only small amount of EQ in the bass, and would sacrifice the eq just for a test.
To try a simpler system, I would like to tap the fullrange signal from the main speaker, and LP it to the sub amplifier. I have got hold of a 12dB RCRC schematics which I'd like to try.
Is there any other suggestions on solving this? Any experience on wheter I should just stick to the Behringer, or try something else?

I could also tap the linelevel signal and feed the Behringer and just do the bass trough the DCX. But the signal would be quite low.

Suggestions?

best regards
