    Confused by definition of infinite baffle?

    I've always wondered this, but never bothered to ask: why is a speaker with an "infinite" enclosure called an infinite baffle, when a baffle refers to the front of the speaker, not the enclosure.

    Technically infinite baffle refers to any situation where the rear-wave and front-wave can't come together. So a small sealed box or a driver mounted in a wall are both technically IB's

      Interesting. So the industry adds to this confusion by labeling open-backed in-walls as "infinite baffle" and back-boxed in-walls as "sealed" when, technically, they're both infinite baffle?

        Doesn't the wave still interact with the driver though? Wouldn't an IB entail the rear waves never interacting with any part of the driver and the front waves?

          By 'interact' I mean the front and rear waves don't physically come together in space.
