    Only way to do that is to swap out the speakers.

    You can't. Well you can, but as mentioned you'd have to buy four new 4 ohm speakers.

    A frequently asked question, for sure. The answer is always the same, it can't be done. If you're looking for 4 ohms to get more power from your amp, you have 2 options, 1) add another 8 ohm cab, or 2) sell the one you have and buy a 4 ohm cab.

    I think you have to put 16ohm speakers in it, not 4ohm, but i'm not an expert by any means, so i could be wrong.

    You're part wrong and part right.

    Four 4 ohm speakers wired in series/parallel will get you a total impedance of 4 ohms.

    Four 16 ohm speakers wired in parallel will get you 4 ohms as well.

    Just a fyi that glockenklang sells a transformer to change a cab from 4 to 8 or vice versa. Might be worth a look at their website.

    1. You can't.
    2. If you think doing so will give you a lot more output the fact of the matter is that it won't.
     
  9. Two things to keep in mind here:

    1) We all know how to do it, but we all refuse to tell you.
    2) SECRETS OF WISDOM AND KNOWLEDGE REVEALED

    Why respond then? It would be far easier to just ignore it, wouldn't it?

    Then again, perhaps you can view the web at only 600X480 and another useless thread (to you) causes unnecessary scrolling.

    At least you feel better getting that off your chest. ;)

    I see that your +1 above was absolutely necessary as well...

    Necessary? No. But I responded to the OP's question, and reinforced BFM's post as well, in response the OP's question.

    Whereas you felt the need to waste your time NOT responding to the OP's question that you also felt was a waste of time. And I got nothing but time today, and I feel like wasting part of it away responding to guys who apparently don't like wasting their time on time wasting questions. ;)
     
  15. 3. But adding another 8-ohm SWR Goliath 410 will! :smug:
