Someone purchased the 50" Bohlender-Gtaebener planar magnetic ribbons that I had on offer here, but wanted only the raw drivers and the notch filters, not the freestanding mounts that I had built or the in-wall mounting parts that the previous owner of these ribbons used. See the photo in my Gallery images. The in-wall parts are free but for the cost of shipping. All in one box 7" x 57" x 4" weighing 16 pounds, from ZIP 18661. On offer for one week only, until next Sunday, December 4, after which I put it out for Monday trash pickup.
