Using a 16 ohm external speaker in an amp with only an 8 ohm output

    Hi,
    I have an extension cabinet with a single 16 ohm 12" speaker.
    Of course, all of the amps I want to use it with only have an 8 ohm output.
    Without introducing more speakers, what would be the best way to knock the resistance down to the cabinet?

    Thanks

    Depending on the amp it'll be fine. Fender amps can do it. What amp is it and how many watts?

    Agree with hank57, most amps can handle a speaker that has a resistance one step higher than the resistance rating on the amps tap. Depends on the amp though. Going to a lower resistance speaker is where it gets more dangerous.

    You'll limit your maximum power to the speaker having it work into a mismatch. In solid state amp's you can predict it as a halving of power. In tube amps it could be a little more or less than half. In your case I doubt the output tubes will mind working into a higher impedance load.

    I do it with my vox all the time.
