B&W Bowers & Wilkins DM604 S3 Mid Driver 7 Woofer ZZ12874 This driver is in very good condition overall, the cone and phase plug are in good shape, it will need a new rubber surround as it has started to harden. These are a mid-bass driver which so far as I am aware, were only fitted to the DM603 S3 & DM604 S3, so they are not easy to come by. Please check your own drivers to make sure these will fit. Driver will need new rubber surround fitted. Surrounds are inexpensive and can be bought here:https://speakerrepairshop.nl/en/rubber-surrounds/bowers-wilkins/rubber-surround-7-inch-for-b-w-zz12874-woofer/a-5630-10000098 Any questions please ask.
