[QUOTE="Electrodynamic, post: 430971, member: 548723"] Heh...this should be interesting. Paper cones offers great effiency with so-so heat disipation. Aluminum cones offer average efficiency with great heat disipation capabilities. Poly offers average qualities of both. (I know I'm going to get reamed for this one) Surrounds. Foam is more efficient. Rubber is less efficient. Foam has better stretching tendencies than rubber does. Santoprene is the best of both worlds - efficiency of foam with the "longevity" of rubber...even though the new foam surrounds are treated to last a LOT longer. However, santo. and rubber cavitate under extreme stress (AKA: severe SPL applications). Basically you will find people / mfg's stressing one thing over the other because frankly, they use a certain product over the other for a given reason. I seriously doubt you will find a hardcore, dead-set, un-foulable cone/surround combo. It simply doesn't exist. Now let the flaming begin. I have a feeling that what I've just posted will cause some people to become a bit perturbed. [/QUOTE]
