Members solderjunkie Posted August 17, 2008 Members Share Posted August 17, 2008 I am buying a GK1001RB-II From my reading: the GK bi-amp setup uses the second smaller amp to power the horn in GK cabs. The smaller amp has a crossover to only send high frequencies to the horn. I don't like the tone of horns or comp-drivers... too nasally and nothing but string noise. What if I used the bi-amp feature to power two small drivers... like two 5" drivers??? I have room in the cab to add the drivers and I could isolate them in their own little box (inside the cab). I can add them where the horn is now mounted. It's not connected anyway. I just need to know the best box volume, right? I am also changing my main speakers to neos... I'm still running the 2 x 12, 2 x 8 cab. The Rig O' Doom needs a facelift. Link to comment Share on other sites More sharing options...
Members 82Daion Posted August 17, 2008 Members Share Posted August 17, 2008 It would be relatively easy-you'd just need a 4-conductor Speakon connector on the cabinet, and you'd then have to wire the driver for the highs to the correct points on the Speakon. I don't know if it's the same for the 1001RB-II, but my 1001RB has the 50W horn amp on pins 2+ and 2- of the 4-conductor Speakon. Link to comment Share on other sites More sharing options...
Members mlwarriner Posted August 17, 2008 Members Share Posted August 17, 2008 i'd pondered this when i got my 1001RB, but because of the crossover point of the head, the 5" drivers won't do much. they're going to see "tweeter-range" frequencies, rather than mids and upper mids. my opinion is that if you're going to add mid-drivers, you'd be better off to just wire them in with the rest of the drivers, with a high-pass filter to stop the lows, but let everything else through. my $.01, FWIW.

Members fretless Posted August 17, 2008 Members Share Posted August 17, 2008 @ 5 K it's gonna be bright Yeah 82Daion's correct but it may prove tricky , you need to use a speakon and rewire it , the tricky part will be cutting into the crossover . Too bad it doesn't have a 50 watt amp out like the 800rb it would be super easy . I would just crank the piss out of the full range amp and turn up the treble Link to comment Share on other sites More sharing options...

I would just crank the piss out of the full range amp and turn up the treble I have the Peavey head dialed-in with some high mids and treble. The horn is disconnected and all four speakers are running full-range. No crossover, no low-pass, nothing The 12's are 16 ohms, the 8's are 8 ohms each wired in series... so the amp pushes three 16 ohm loads in parallel (~5.33 ohm cab impedance? ) I want to change to some neo speakers in 16 ohm, so I can run them parallel for a 4 ohm load. Can you recommend a horn or compression driver that I will like??? one that's not so icepicky? Link to comment Share on other sites More sharing options...

"Can you recommend a horn or compression driver that I will like??? one that's not so icepicky" actually I can't , but I think your choices are piezo or ribbon and or horn or dome , some sound way better than others , I think the best I've heard was in a Euphonic Audio coaxial cab , that was sweet to the ears .
