Rewiring for biamp - Aguilar and GK

Discussion in 'Amps and Cabs [BG]' started by Bryan Caldwell, Apr 25, 2006.


  1. I'm using an Aguilar GS 112 with a Gallien Krueger 700RB-II. I was wondering if anyone has experimented with rewiring the cabinet to take advantage of the GK's biamp capabilities. I would imagine it would be pretty simple to bypass the cabinet's internal crossover and connect the woofer and tweeter to the Speakon connector (already 4 connector). Any way to keep the 1/4" connectors as full range?

    Any thoughts?

  3. I'm not sure exactly how you could keep the 1/4" jacks full range (using the crossover w/woofer & tweeter.) Probably there's a way you could wire in a switch.

    But, if you properly connect woofer and tweeter to the 4 speakon terminals, I think you could connect the woofer only to the 1/4". Then you could drive the woofers through the 1/4', or biamp woofer/tweeter with the speakon.
     
  4. Christo,

    That was my thought. Just wondering if anyone here has done something similar. Thanks.

    Bryan, I looked into that myself. I spoke with someone at Aguilar-who mentioned the woofer/tweeter cross-over point being close to 2.5 khz.

    Hope that makes sense. I tried it with a Bergantino HT115 and the higher cross-over point was not compatible with the components in the Berg. It was too dull in the upper mids as a result. I think the GK bi-amp feature works better with GK cabs. The GK Neo 112 cab I have has more upper mids than the GS 112 which makes the bi-amp feature a better fit.

    (due to the high cross-over freq 5khz-on the GK head, I found the horn lacking some crispness in the "dead zone" from the woofers natural roll-off point around 2khz. Annd the tweeter cutting in at 5khz as a result of a "hole" created by the new cross-over point made it less desireable for my tastes.)
