GK 400RB Ohm Question

Discussion in 'Amps and Cabs [BG]' started by Tom Neves, Oct 21, 2004.

  1. Fellas,
    I have an old GK400RB and want to know if it's a problem running 2 Bag End cabs at the same time.
    S15D = 8 ohm
    D10X-D = 4 ohm

    My GK manual states 8 ohm, 2 maximum or 4 ohm, 1 max.

    I have used the two together a few times with no problems, but am wondering if this could result in any serious damage?
    Any techs out there.
    Thanks :help:
  2. You are not ok running those two cabs together, you will most likely blow the power amp section like that.

    What they mean by this is that you can connect either
    2 - 8 Ohm Cabs
    1 - 4 Ohm Cab

    So the lowest your amp can handle is 4Ohms

    An 8Ohm cab + a 4Ohm cab would equal somewhere around 2.667Ohms I think.
    This is below what your amp can handle
