Genz Benz GB 610T-XB2 wiring diagram

Sign in to disble this ad
Hey there, anyone would happen to have said wiring diagram? I would love to have a look at it. I sent Jeff an email and I'm sure he'll get back to me on Monday but for the time being, I figured I'd try my luck here!

Pull a handle or something and see if you can read the back of a speaker, or pull one and test it. If they're 24ohm speakers, they'll all be wired in parallel. If they read some other impedance, could still probably reverse engineer it.

The individual speakers are 8ohms each or it's an 8ohm cab?

If the individual speakers are 8ohms each, you could still do it in series/parallel and end up at 5.33. That's close enough to label it as a 4ohm cab.

4ohm cab, 8 ohm each. There's a crossover for the tweeter also.

Can't get the diagram to post.

Go about 3/4 of the way down the page until you see this:

"2 sets of 3 speakers in parallel, with those 2 sets in series:
For 4 ohm speakers, you get a 2.67 ohm load.
WARNING:Power amp must be able to drive a 2 ohm load

For 6 ohm speakers, you get an 4 ohm load.

For 8 ohm speakers, you get a 5.34 ohm load.

For 16 ohm speakers, you get a 10.66 ohm load."

Here: http://www.colomar.com/Shavano/spkr_wiring.html


Basically you connect the + terminals of 3 speakers running down one side of the cab to the + terminal of the jack. Then connect the - terminals of the 3 speakers running down the other side of the cab to the - terminal of jack. Then use a jumper to connect the remaining open + and - of each pair. It's like wiring a 410 with 2 extra speakers strung to it. In this case it will technically come to 5.33 which would be marketed as a 4ohm cab for amplifier protection/chaining cabs, etc. The difference in amp power between 4 and 5 ohms is for practical purposes nothing.


The tweeter is likely a high pass filter only meaning the woofers are playing the whole signal and just the lows are kept away from the tweeter. If it is a true crossover, where it takes treble out of the woofers too it'll have more than one coil on the circuit board. Simply....just connect the tweeter the way it was.

Correct Will, Anything between 4 and 6 ohms is nominally a 4 ohm load. Nothing worse than a real load being LOWER than a nominal load, though some manufacturers seem not to have a problem with this. Those of us amp designers here hate them, it can be hard on output stages and we have to consider this kind of stuff when developing our protection circuits, otherwise the end result could be "unfortunate". I have seen some really surprising impedance plots.

Bump for the actual GB diagram. Anyone? I know this is a long shot though.

Series connection of 3 parallel pairs of drivers. That's all there is to it.

Thank you Will and agedhorse, most appreciate the feedback!
