If you go to an active crossover, i'd obviously use the Audio X-stream crossover, which incorporates a tuneable notch filter for the B-Gs. I forgot about it. Better would be only a tube crossover IMO.I think that the passive notch filter ahead of the speaker is probably a severe limit on sonic quality - i prefer to implement such filters with a parallel 'sink' circuit, not a blocking 'tank' circuit - if i have to.
It is probable that a text-book crossover will work quite well from the start on the B-Gs, because they have a rel. well behaved fundamental resonance at ca. 130 Hz, so the used crossover is about two octaves away, and the bass will be at least 2 octaves away from its upper limit. The used XO frequency sits nicely (and sensibly IMO) between both drivers lower resp. upper limit. A bit of tuning will probably still be necessary.
What preamp and amp do you want to use?
