JBL Patented Plus One™ Glass Fiber Woofers with Rubber Surrounds
Plus One™ glass fiber woofer cones are lighter and stiffer with up to 25 percent more active cone-area than the competition. The result is remarkably accurate sound with high SPL performance. The hi-roll rubber surrounds allow the woofer cone to move freely and emit bolder bass.

Oversized (35mm) Woofer Voice Coils
Oversized voice coils with extra copper and surface area serves to dissipate the heat for improved reliability, enabling maximum power handling with low distortion.
