Fender Super Bassman 300 w/ 3x Genzler BA210-3?

From the BassGearMag.com: Inputs/Outputs: Two Neutrik® Speakon® jacks; two ¼” jacks Genzler BA410-3 and BA210-3 SLT Bass Cabs | Bass Gear Magazine
Chain all three and plug into main speaker input.
You may want to cover the extention jack no one will plug in another cab in error.

Contact Fender or Genzler for more info.

 

Chaining at least two cabs together is what parallel speaker inputs are for, ItsMatt. The unused parallel inputs automatically become outputs to other cabs!

Hmmm, but I didn't see BassGearMag.com recommending chaining all three cabs from the main speaker output alone. Maybe that'd be OK, I dunno.

However, I see the Super Bassman manual recommending chaining two cabs from the main speaker output and one cab from the extension speaker output, and then you don't need a cover for an unused speaker connection on the amp. But don't let anyone plug in any more speakers to those cabs! And be sure to set the impedance switch to 4 ohm, per the manual.

@ItsMattIThink --- thanks for using our cabs with this Fender amp. You'll be running a 2.67 ohm load off the amp with 3 of the BA210-3 cabs connected to it. Let me check with my friend Dave at Fender who designed this amp, just to make sure which connects on the back of the amp you should connect to.
Under most amps, I'd say 1 cab connected to the amp, and the rest of the cabs connected to each other---daisy-chaining them together. I would think you could plug them all into the main speaker output and set the Impedance switch to 2 ohms BUT..... Let me check and get back to you.

 

Hmmm. I wonder 4 ohm or 2 ohm setting? Thanks @Jeff Genzler that would be appreciated

 

I talked to Dave tonight, run all 3 speaker cabs from the Main output jack, daisy-chain the cabs together and set Impedance Sw to 2 ohms. That is the way to go to run your 3 BA210-3 cabs. If you're considering a 3rd cab, I'd recommend you take a look at the SLT version for a little variety in configurations.
Hope this helps.

 

@Jeff Genzler, I don't suppose Dave mentioned why the manual (above) to his amp says 4 ohms on the main and 8 ohms on extension, set to 4 ohms?

You got it. Any of those.

Yup, says 4ohms in the manual.

 

Yes, @G-Dog is correct, on the cabinet jack panels, you can use any jack to jump from one cab to another. Input into One Speakon and Out to the next cab from the second Speakon. Frankly you could go Input into a Speakon and out from a 1/4" jack to the next cabinet. All inputs on the rear panel are parallel so they are all available for Input/Output use. Hope that helps.

 

Yes, this would be a total 2 ohm load and I'd also take our a higher level of homeowners insurance for damaged windows !! Seriously, that would be a phenomenal combination of cabs.

 

You would daisy chain the two 8 ohm cabs (paralleled for a total of 4 ohms to the head) and plug them into one of the outputs on the Fender and plug the 4 ohm cab into the other output.
