  • New speaker tech

    This looks interesting, not really new as these are basically running a piezo type motor but the manufacturing techniques appear to allow scaling to less expensive and more consistent quality. They also promise high sensitivity and low distortion.

    Here's the rub... they're tiny. This is obviously targeted at small in ear monitors and ear buds rather than blast your face off speakers we love to build. In that market, the voice coil remains king.

    If somebody thinks there's any money in it, maybe they'll do like the old Motorola piezos and slap a waveguide on one for a tweeter. Those sounded really good if you EQed them properly.

      I'm trying to figure out what exactly it is. Is it just a tiny piezo?
      Isn't it about time we started answering rhetorical questions?

        The subject is a bit broader than that;

        but yes, in this case it seems to simply be a piezo driver.

          The one speaker tech that intrigued me is the new Børresen Audio iron-less motor topology that is present in their new line of speakers. Very clever that Michael Børresen!
