Presentation
The B&C Speakers 21SW115 4 Ohm is a 21-inch (54 cm) subwoofer driver with a power of 3400 W AES with excellent low-frequency handling capacity.
With a sensitivity of 96 dB at 1 W/1 m and a frequency response extending from 33 Hz to 1 kHz, this model ensures exceptional performance in the field of bass reproduction, while maintaining remarkable clarity and precision.
The 4 Ohm impedance, coupled with a 4.5-inch (116 mm) copper voice coil, allows efficient heat dissipation and optimum performance even under intense stress. The radial cone with front and rear waterproof treatment as well as the triple roll suspension guarantee excellent durability.
Its large neodymium magnet provides high magnetic power, reducing the risk of distortion and allowing the speaker to deliver deep bass with great linearity.
The speaker has a maximum excursion (Xmax) of 14 mm, providing significant air displacement capacity for very high sound pressure levels.
Its frequency response and suspension characteristics make this model an ideal choice for high-performance subwoofer configurations, such as those used in large-scale sound systems or high-end home theater installations.
