4 to 8ohm conversion?

Discussion in 'Amps and Cabs [BG]' started by Jon R, Aug 26, 2003.


  1. I just located a Peavey 210TVX at a price that would be hard to pass up... only problem is that it's 4ohm and I need a 8ohm cab. Can it be converted to 8ohm?

    um, i think the only way you could do that is by changing the speaker

    Yeah, I don't think there is a way to wire it to 8 ohms without replacing the speakers. I think the only other way you could wire it would result in an impedance of 16 ohms.
     
  4. Hmmm. Shows what I know. :D I assumed that it had 2 8ohm speakers in it and that by switching from series to parallel (or vice versa) that I'd end up with an 8ohm load.

    if your have 4 speakers of 8 ohms, you can get an overall load of 8 ohms, but not with 2.

    Try connecting 4 ohm resistor (if you can find one) in series with speakers.

    I don't know if it will alter your sound.

    Still, it is worth a try if you really want to buy that cab.

    I forgot to say something about power loss. Speakers will get only 50% of power from your amplifier. Other half will dissipate on resistor so you will have to drive your amp harder. I would recomend waiting for a better shot with some other 2x10 cabinet.

    NOOOOOOOOOOOOOOOOOOO that wee resistor will fry, have you anyidea how hot it would get? DO NOT under any circumstances add a 4 ohm resistor!

    Oops, it was just idea. I always wondered if it could be done. I guess I shouldn't recommend stuff that I haven't tried first to other people. Thanks for enlightenment.

    A speaker cabinet with 2 8ohm speakers can be wired 2 different ways.

    If the speakers are wired in series, it would be a 16ohm cab.
    If they are wired parallel, it would be a 4ohm cab.

    Does the cabinet also have a horn (with a crossover)?
    If so, you may not be able to rewire the cabinet without affecting the crossover point. Going from 4ohm to 16ohm may change the crossover frequency.
     
  11. Hi,

    I've got a similar question:

    My cabinet is a Peavey 410 TVX, 8 Ohm, 350 Watt RMS and it's got four 10 inch Sheffield TVX 1035-8 Ohm-MI Speakers.

    Now, would it be possible to rewire this cabinet to 4 Ohm??

    I don't need a 4 ohm cabinet, but it might be nice to know if it would work out...

    Thanks,
    Bart

    No, it's not possible. It can be wired to 2 ohms in parallel, 8 ohms in series-parallel (as you have it), or 32 ohms in series.
     
  13. Thanks!
