Presentation
The B&C Speakers 21SW152 4 Ohm Push Buttons is a 21-inch speaker designed to deliver deep, powerful bass with impressive power handling. It is aimed at professional sound systems requiring accurate reproduction of the lower end of the spectrum, even at very high levels.
Its design is based on a 6-inch (152 mm) copper voice coil mounted on a fibreglass support, capable of handling up to 2000 W AES continuously. Combined with a large neodymium magnet, it guarantees remarkable efficiency and very low distortion, even under extreme loads. The 21SW152 also boasts a sensitivity of 96 dB, a BL force factor of 32.5 T-m, and an Xmax of ±15 mm, giving it exceptional dynamic range and remarkable accuracy in the low end of the spectrum.
Designed for high-volume cabinets, it operates ideally in a load of around 190 litres tuned to 33 Hz, offering a balanced and controlled response from 30 to 1000 Hz. Its triple-roller suspension and rigid diaphragm with front/rear waterproof treatment ensure exemplary reliability and longevity, even under heavy use.
Robust and powerful, the 21SW152 is the preferred choice for high-end subwoofers used in concerts, clubs and touring applications, where power and precision must go hand in hand.
