    Description

    I'm helping my uncle to sell items he collected during a lifetime as an audiophile with strong analog, tube, and DIY affinities. The driver was used sparingly in a single-speaker, infinite baffle arrangement. He drove it with a low-power, single-ended amp. (See also our Scott listing). It performed perfectly when we tested it with an audio signal.
    Retail on this driver is now about 1850 € (excl. VAT) or 67 (as of Dec 28, 2019)
    We retained the custom-made hardware used to mount the driver in case it is useful to the new owner. It's made of what looks to be 1/2"-thick delrin or a similarly tough plastic-like material sandwiched with cork. We can remove the hardware before shipping, but the driver unscrews easily; no adhesive was used.
    Note, this is the '1B' model with increased bass response relative to the '1' model.
    AER renamed their products, so this model is now called the BD 1B; we believe the driver is identical to the current model despite the different designation.
