Hi,there,How do i Refoam may :JBL L65-12″ Woofer?Purchase in 1974 Ser,no:52055-52252,Refoam Kit?…..Many Thanks in Advance,…Aksel.
You need to use the RFK128 JBL kit and select DCP3200. If you are asking how to do it, here are the instructions
I have a set of L100t’s and the foam around the woofers has disintegrated. Is there a more durable replacement for the foam? Thank You.
It is very typical for the foam surround to dry rot. This dry rot also occurs on butyl rubber surround speakers. Depending on where you are in the world and the environmental exposure your speakers experience, you can expect this to happen every 5-20 years. You can change the cone to an accordion edge surround or an all paper surround but you will sacrifice low frequency response. The speaker cabinets were tuned for this type of speaker and surround so I say just repair them as needed. You can send them to us for us to refoam or recone or we sell do-it-yourself parts as well. Contact us at info@speakerex.com for more info.
I have a pair of JBL 4311B Control Monitors I would like to have repaired. Do you provide this service?
Hello, yes we do!
I have a set set of 1976 vintage JBL 100’s. I am currently making new cabinets using the old boxes as templates. When replacing the fiberglas insulation on the back and sides, what do you recommend
Thank you for your prompt and informative reply about the insulation for my JBL 100’s. I forgot to take a picture of the front of the speaker when I disassembled them. I can’t remember if the posts that mount the grilles were in the cabinet fronts or in the grilles. Which way should they go?
Thank you in advance.
