    Can the Ot on a drri handle a 16ohm speaker? I have a 16ohm et90 sitting around I'd like to throw in it.

    You may want to check the manual. It answers that question for you. The answer is no.

    Ok Thanks. I don't have a manual. Likely should be able to download one somewhere.

    "

    Note


    that the amplifier is optimized for an 8 ohm speaker

    load, and that the speaker in the cabinet is 8 ohms.

    Should a total load of more or less than 8 ohms be used,

    the amplifier will not put out its maximum power before

    distortion occurs"

    Doesn't say it won't work..

    Ive read hear of guys using a 8ohm extension with the internal 8ohm, for a load of 4ohms without issue. So would there really be an issue using a 16ohm speaker on the 8ohm tap?

    No problem running it at 4 or 16 ohms, just a little less output.

    Actually, you could have a problem running it at 4 ohms but not at 16 ohms.
    The amp needs to "see" at least the amount of ohms it requires. If it "sees" more, no problem. You may notice some changes in sound.
    If it "sees" less you may just blow it.

    Yeah it'll be fine...maybe not if you're running it on 10 7 nights a week but generally speaking it'll be okay. The transformers in the reissues aren't super robust but it'll be okay.

    :aok

    Fender says YES.

    This is backwards for tube amps...it is correct for ss amps.

    I may be wrong but for more than 1 year I used my 65Amps London Pro in the 8ohm setting with a 16ohm speaker!
    When I asked Dan Boul about the speaker he told it was 16ohm speaker but using it in the 8ohm setting would not be a problem at all.
    The opposite yes. I could blow the OT.

    The question was regarding a Fender and the response(s) regarding Fender's recommendation, not 65Amps. Often you can get away with ignoring the MFG's recommendations....sometimes you can't.

    Regardless, a higher mismatch (spkr. to amp) poses greater risk than a lower one....this is a fact.

    "A speaker impedance load of 8Ω should be used to avoid distortion or damage to the amplifier."

    I wouldn't put the 16 ohm in personally. So many great 8 ohm speakers out there. Sell the one you got and find something rated for 8 ohms.

    Yeah I'll maybe sell it and get another one at 8ohms.
    I do have two 1x12s 16ohm each in parallel for 8, I could just use those at home and disconnect the internal. Then when I go play out I can use the original 8ohm jenson alnico.

    So, having different brands make them work different with speaker impedances?
    Cause I was talking about a general rule, not about manufacture recomendations.
    I have to say I also own a Fender DRRI and used it with the 16ohm speaker with no problem.

    To my thinking, there is no better 'general rule' than to follow the manufacturer's recommendation. Obviously all amps are not designed identically. This topic is frequently posted here (TGP) and on other forums with always the same comments. Why risk it for the price of a speaker? But it is your choice to do so....somewhat like 'travel at your own risk'.

    Most pedal manufacturers that have power supplies recommend using only their power supply with their pedals. Do you follow the recomendations or "take risks"?
    It's just physics! You won't arm the amp if it "sees" at least the amount of impedance it asks for.
    And I really don't know where you got the idea that it was only for SS amps and backwards for tube amps!
