    Hi all,

    I’m looking for a bass cab I can run two amps into. I know you can do this with some Ampeg cabs, and the Peavey Megabox (2 x 8, 1 x 15), which basically have two inputs (not series inputs) so you can run two amps into them, one dealing with HF, and the other Sub frequencies. It’s like bi-amping but within one cab. The main reason for wanting to do it is to save space, otherwise I’d just pick up two cabs!

    Keen to hear from people with suggestions!

    Feeding two separate amps into one speaker cabinet is rife with danger. Even if the cab is splittable if something went wrong the OP would likely lose both amps.

    With more and more amps running in Bridge the grounds within the cabinet would need to be completely isolated.

    Don’t think that’s strictly true... both the Peavey 1516 & the Ampeg SVT 810E allow a safe connection to two amps safely.

    Carvin RL6815 Cyclops was built to be bi-amped, with separate High and Low inputs. This means your amps must have a crossover before the cabinet. The one I owned was unique in that it had a built-in crossover with a third "full range" input. Very heavy old beast, sounded good but I quickly tired of the 120 lbs. combo. It didn't really fit in the trunk of my Corolla and it was hard on the interior of the back seat.

    I don't think you'll find anything newer, as bi-amping isn't very popular anymore. It's usually more trouble than necessary, and with good full range amp and cabs available today not worth it.

    What amps are you trying to connect and why? There is probably a safer/better solution. Are you looking for something smaller than a 2x10 cab sitting on a 1x15?

    GK cabs are biampable.

    Believe what you will. I stopped using 1/4” Phone jacks years ago as they are, in this day and age, an inferior and obsolete connector for the power levels typical bass amps work at.
