Recone kit for the Cerwin Vega W15-p woofer used in the PD9 and probably others. These were developed specifically, exactly, for this woofer. Ribbed cone like the original and pleated accordion surrounds.  Precision voice coils, on ALUMINUM formers like the originals. Several years, and more recones than I can count went into developing these to provide kits that not only take the pounding that I know you're going to give them, but also match the t/s parameters of the originals. These kits are different from the other kits available in several ways. All the other kits I have seen, use the 5H2040 cones. Those cones were originally developed for the eh series woofers, which were very different. They used a smaller spider which sat down inside the typically used landing, so those 5h2040 cones at 3.825 deep, are too deep to sit properly when using the correct spider. Also, since those EH series woofers were used as a midbass in sound reinforcement tops, those cones are extremely thin and light. About 26 grams, which is half of the original W15-P cone weight. Plus the surround ribbing has much shallower ribs, limiting excursion. These new Brew City kits solve all those issues. A close look at the surround, and comparing these to the originals, and the other kits out there, will tell the story. Plus these are much stiffer, and weigh in at 52g. The only drawback to these, is that the ribbing doesn't go down the cone quite as far, which could not be avoided. Most spec sheets specify a 3.75" dustcap which is included, however I have seen some of these woofers that appeared original with a 4.5" dustcap, so if you want the wider cap instead, just let me know and I'll pack those for you. Kits include everything in the picture. Shims available on request. Also included is a sheet of tips and suggestions from decades of experience, along with my personal phone number should you have an issue. If you have any questions, or want a specific bunch of parts put together for you, let me know. I'm here to help and happy to put together any combination of parts you need. 19 years on Ebay, selling mostly speaker related stuff, and mostly Cerwin Vega, with 100% positive feedback. Will be packed securely and shipped promptly. Thanks!
