Description
It features a unique "racetrack" shaped cone that provides more cone area than a standard 12" round woofer, fitting into the same height space as a 10" woofer. The SPG555 utilizes a patented 3.5" RVC (Removable Voice Coil) and RadialVent cooling system for thermal management.
Construction includes an injection molded mica-filled polypropylene cone, a neodymium magnet for a powerful motor assembly, and a cast aluminum basket.
