[QUOTE="LostCause, post: 430966, member: 554344"] Theoretically the best speaker (or subwoofer) would have a cone that has no mass whatsoever...since that is impossible usually the lightest and most rigid cone you can fine works the best... today most highend subs use kevlar (stuff bulletproof vests are made out of) sandwiched between other "space age" materials like Nomex...usually lowerend speakers and subs use paper or polymer cones... I'm not to sure about the surrounds but I've heard some people avoid getting rubber surrounds in cold climates because they can crack if they aren't warmed up...some rubber surrounds also fade in the sunlight or get damaged by moisture...usually a surround that has good dampening characteristics and allows good cone excursion is a decent one...most high end subs and speakers use Butyl Rubber Surrounds...others use foam... - Lost Cause [/QUOTE]
