About 6-8 weeks ago I made a pair of protoype Smith horns for my DIY JBL's. They were simply laid on top of the speakers, the L91's were removed and the holes blinded. "It will stay like this for a while." I told my wife, thinking 2-3 months. "OK" she said. 6 days later - "Time's up" she said (She also claims it was 8 days).
Anyway I concluded that the DIY had to leave the living room (to another place with no wife interference) and be replaced by speakers that would not be subject to research & development.
Last week a pair of C-60's came up in Denmark, which is just (short) trip.
I have started looking over the cabinets and drivers.
First I hooked them up at very low volume. All drivers play. The lansaloy is gone completely, and was replaced by tape. I have now removed the tape.
Step one is obviously to order new surrounds. Is it possible to get JBL surrounds?
The speakers have been stored in a humid environment. Much of the lacquer is gone. There are a few deep cuts. I have spotted small dark spots all over the speakers (see close up). Are these spots ment to be there?
Also the back panel and the baffle needs repainting as the particle board is starting to come through the paint.
Do anyone have recommendations / schematics for new crossovers?
Lots of work to do, but it's worth it for house peace.
