Product Details
The B&C Speakers 21SW152 21" subwoofer's 6" diameter voice coil with a 1" copper winding length provides great Xmax (15 mm) and impressive power handling (2,000 watts RMS). Despite the driver's size, a high-strength neodymium ring magnet keeps overall weight as low as possible. The 21SW152 will deliver nearly unmatchable low frequency output when loaded into vented or horn loaded enclosures. Perfect for high output concert and nightclub applications.
