JBL D120 F repair?

Hi,

I have an origonal coned gold label JBL D120F Signature speaker and it has a small radial tear to the speaker . The tear shows signs of propogating further, but runs to about 2". The tear would only propogate to the 'glued' area and not into the speakers center.

The tear is on the outer 'glued' and formed part of the speaker and about 1/2" in from the speakers edge.

Could I repair this? and What's the best method and materials to do it please? Also what's best to clean up the cones - dust and dirt evident.

 

Thanks for the advice. I ended up using PVA adhesive in several coats. It's certainly seems to have done the biz and it dries clear + is flexible.

The bad news is that the other one of the pair has bad voice coil drag - it grates when you gently push forward on the cone. I don't know if there is anything to do on this appart from a recone. Could I save the dome or somehow remove the cone and straighten the deformed ring inside? I fear not!

I have that 1st speaker in my twin and it sounds great .. gentle on the treble though. It's paired with an oxford - seems to be a blue stickered oxford with Fender on and I think '73.

The recone I was quoted £119 + vat @ 17.5%. (1.75USD =£1) ... so I think that's not cheap to say the least. Maybe that's what you have to pay on this speaker. Advice?

 

I'm still waiting for their reply on that mike. i did ask for a quote with 'authentic parts' though. They do work or have done for Knopfler and Clapton, so they must be pretty good and a close friend has recommended them. I have seen re-cones done with a paper dome and they don't look good and probably don't sound it either.

Thanks for the thread ... i'll give it a look. I just sort of half wondered and clutching at straws whether it is possible to partly reshape the inner cylininder in the voice coil in order to achieve clearence...... if you manage to get the aluminium dome off from the front, (but it sounds like I might be dreaming on that one!)
