Beautiful pair of woofers, professionally reconed. All new parts with voice coils on aluminum formers like Cerwin Vega originally used. These were used in the LS12 and E312 (E312 also used the cvw12 in some) If it leaves my shop, it's good to go, without issues, and ready to rock, guaranteed. 4 ohm woofers.  Over 20 years on ebay, selling mostly speaker stuff, and mostly Cerwin Vega drivers, kits, and parts, with 100% positive feedback. I pack like they're gonna drop it from a plane, and ship out within one day either USPS or FedEx. Thanks!
