In Reply to: Re: Foam or rubber surround? posted by gearhunter on February 22, 2007 at 14:00:23:
Just because a material is more durable does not make it better. Infact, at on time the cheapo speakers of the 70s had a lock on rubber surrounds while the high end speaker employed foam.There are extremely expensive speaker manufacturers that have elected to use foam on selected drivers for reasons of sound and transient response. For example, in the *same* system the low frequency driver will employ a rubber surround while the upper bass driver will employ a foam surround. It was compliance and transient response issues that lead to the decision not the minimal cost difference.
To be sure, in recent years as rubber and other materials have been fashioned that match (or perhaps exceed) the behaviorial characteristics of their foam counterparts foam (with good riddance)has become less used (although new treatments for foam can extend life to more than twenty-five years.
