Since 1990, I have enjoyed collecting and restoring antique radios and vintage audio.... all items I list will be exactly as described and packed extra well to ensure a safe delivery... buy with confidence! BUYER is responsible for doing their own research to ensure they are buying the correct woofer / part for their Velodyne subwoofer, application, or DIY project. And... for judging whether part is compatible with their speaker's specs ! Once purchased, the order will NOT be canceled for any reason, and there are NO RETURNS! Ask any and all questions BEFORE buying ! For sale is a single 8" cone WOOFER removed from a Velodyne model V-810X-B powered subwoofer that had amp issues. It works great but will need a new foam surround installed before using. DCR measures about 7.3 ohms. Has a heavy magnet, and a protective metal bell/shield attached to back which might be to make sub "video shielded" ? Woofer weighs about 8 lbs. Following #s are on a white paper label on rear bell shield.. not sure what each # represents: 71-00B, W87WL7E-1, 0755 I have already carefully removed the outer/top paper gasket, and also shaved all the flakey old foam from the cone's outer rim and the frame's outer rim. Buyer will still need to cut away the residual glue from the frame's outer rim before installing a new foam surround. The model V-810X-B sub was from the VA Series of subs. Please excuse the blurry pic showing the front view of woofer. The cone, dustcap and spider are all in great shape ! Ask any and all questions BEFORE buying! Once purchased, the order will NOT be canceled for any reason, and there are NO RETURNS! After buyer has left positive feedback to acknowledge everything OK, I will immediately return the favor.
