B&C 21 Inch Drivers

Welcome to our selection of B&C 21-inch (530 mm) low-frequency drivers. Representing the absolute pinnacle of large-format subwoofer technology, these gargantuan transducers are engineered for elite sound reinforcement systems that demand unmatched low-frequency extension, massive air displacement, and relentless power delivery.

This category features flagship models—including the legendary DS and SW series—equipped with heavy-duty voice coils ranging from 116 mm (4.5 inches) up to an industry-leading 153 mm (6 inches). These massive motor systems allow the drivers to comfortably manage continuous program power levels from 3400 W to a staggering 5000 W. Built with premium neodymium inside-slug magnets to optimize flux density while keeping total weight manageable, B&C’s 21-inch subwoofers feature dual-silicone spiders, high-excursion triple-roll surrounds, and front-and-back waterproof cone treatments. They are the ultimate choice for touring infra-sub bass systems, high-end club installations, and large-scale outdoor festival arrays where physical, chest-thumping low end must be maintained without distortion.
