What's the LARGEST possible speaker? I'm talking about what's possible.

Discussion in 'Amps and Cabs [BG]' started by T-boneParish, Jan 14, 2021.

  1. I know there are 18"speakers. Prolly a lot bigger. I imagine humanity could build a speaker that is a LOT larger using special materials.
    Which got me thinking... What's the largest functional speaker ever built?

    You don't need to have ONE really large-diameter speaker to have loads of SPL:

    I've seen at least a few 24 inchers, Precision Devices have a couple for starters.

    You buy 34" or possibly larger drivers, but AFAIK they are pretty rare.

    I believe ELP toured with these on the "Welcome Back..." tour.

  14. It’s debatable if you want to call it a “speaker” but check this out.

    There was a story about a guy who played Washtub bass who ran a cable to the center support of a building in Vietnam and "played" it
    In theory, there's no limit to speaker size. In reality. the larger the diameter, the slower the response.
