Hey, this is a question for anybody who remembers the L-100. Remember that 12" woofer with the rubber coated cloth accordion surround? Those speakers not only sounded great but with that type of surround they were almost "bullet proof". I'm sure there are some being used in HT & music systems today. My question is, why does no one use the cloth accordion surround anymore? You see a lot of rubber surrounds on new speakers and some are made of foam, but no cloth. I don't know about the rubber surround, but the foam has a limited lifespan. I have had 2 pair of speakers with foam surrounds that needed to be replaced after five years or so. The only driver manufacturer that uses the cloth surround (as far as I know) is eminence (www.eminence.com). I think all their drivers are made for pa systems or for club music systems. This is just a question that I have not seen here in the forum before. Maybe someone can shed some light on this. Thanks for a great forum!
