There was a big batch of JBL Sub 1500...15" subwoofer transducers... that were sold through Parts Express 20+ years ago. There was a defect in some adhesives where the spider meets the cone and voice coil, subsequently leading to the bond to fail. This is the second unit I've repaired with this failure, with another in the shop coming up for a similar repair. These things are expensive...with no factory recone kits available, and no aftermarket kits available, other than a suitable replacement spider and dust dome. The cone and voice coil are dang near bullet proof. It's also used in a Revel Subwoofer...Revel is actually printed on the voice coil former. Sorry I didn't show that...trust me. It takes LOTS of time and diligence to separate the cone from the frame. The previous repair shop gave up after quite a long time...so it ended up here...to be completed with excellent results. Enjoy the process.
