But just spoke with Dutch @ Vin-Tone and he said its possible to damage the cone trying to replace the cover, especially considering the goop issue. He also said that JBL is now making the E kits in Mexico and the build quality is marginal at best. Well, that really sux. And the comment about a Weber recon'd D120 sounding just like a Weber didn't do.much more me either.
Now, he said a E-kit reconed D will never sound exactly like and original. But since Jerry went they different JBL incarnations, would the original D and E-kit D be a nice belnd together?
The original D120 with the E120 kit will sound like a K120 so you get the best of both worlds (higher wattage rating but alnico tone). But still, if the speaker works, just play it and enjoy it. You said it had "E120" written on it. It's probably already reconed with a E120 kit. You can't improve it. Any pro speaker repair will be able to cut out the old dust cap and glue in a new one without damaging the cone or voice coil. Don't do it yourself. Pay $20 for someone else to do a clean install.
