A portable, dual 21-inch subwoofer designed to provide gut churning impact and solid musicality â€“ not just infrasonic effects. Its 6-inch voice coils, strong neodymium magnets, unusually rigid cones, and innovative low-turbulence ports permit an optimal tuning to be achieved in an enclosure that is light in weight and truck-pack friendly. It is perfectly suited for highly dynamic touring systems, live performance venues, and nightclubs. Its massive output capability matches that of two to three conventional dual 18-inch subwoofers, reducing transport costs and saving precious truck space and venue real estate.
