This rubber surround allows the subwoofer cone to efficiently move air while staying cool. This technology allows for 13mm of one-way excursion that creates incredible accuracy from the subwoofer.

A Dual Voice Coil (DVC) with easy configuration jumpers make installing the S-Series subwoofers a breeze. A new twist-lock grille mounting system makes it easy to install and remove an optional grille without mounting screws for added protection to the cone.
