This listing is for a pair of vintage Bang & Olufsen 8" woofers. At some point, the previous owner  woofer had the cone with surround replaced by a local speaker recone shop. The shop does not refoam speakers & the original owner wanted to keep the original voice coils. The repair shop cut back the existing cone & glued the new cone with foam surround over the existing cone. Woofers have been tested with music, a 30Hz test tone & a multi meter. Both are in very good working condition. One of the foam surrounds was punctured & has been repaired (see picture #4). I installed new 3.75" cloth dust caps (the paper dust caps that were on the replacement cones were dented). Impedance is 8 ohms & DCR = 6.6 & 6.8. Woofers have 3" voice coils. The trim rings are glue on & should not be removed. Basket o.d. is 9 5/8".
