Greetings- I bought a pair of early edition L100 from a gentleman north of me in New Hamshire and he delivered them on Saturday.The amazing thing is that the foam grilles are intact and nowhere near decomposing. I have a feeling that these may not be original JBL foam, so I included a picture for the experts ( Son of a Gun?) to look at. I really don't care if they are original or not, but if they are, how would they have survived this long without deteriorating? ( and how would I keep them this way)? The speakers are to be a Christmas present for my nephew. Thanks very much, wpod
