Hello, Some years ago I got a job of re-coning a pair of 2235H. When I received the speakars I thought they where pretty nice but the foam surround looked bad and the owner wanted to re-cone them. When starting the job to cut out the old cones I decided to take it very easy and I tried to save those old cones to the future. So using a lot of solvent I manage to save them intact. When looking at them to day I discovered that the coil former was made of Aluminum and I cant remember that I have seen a JBL coil former made of Al? Did JBL ever used aluminum in 2235H at that time? My question is: are those cone kits original 2235H cones or is it aftermarked cone kit? data measured: length of voice coil: 19 to 20 mm approx. Total weight of cone kits approx 144 grams (including the black mass ring) DCR measured 6.10 and 6.30 ohms It clearly says "2235 H" on the rear of cones. I have attached some detailed pictures of the old cones so it will be easier to find out what it is.....
