B&C Speakers - 15DS100 4 Ohm

The B&C Speakers 15DS100 4 Ohm speaker is designed to meet the requirements of professional sound systems requiring precise low-frequency reproduction. With a diameter of 15 inches (38 cm), it incorporates a 100 mm aluminum voice coil, allowing optimized heat dissipation and efficient management of the 3000 W AES that it is capable of supporting.

Its neodymium magnet offers an optimal power-to-weight ratio, fast response and better signal dynamics. The triple roller suspension ensures precise control of the travel, while the double silicone spider contributes to the stability of the membrane movement. Its radial cone benefits from a waterproof treatment on both sides for better resistance to harsh conditions, making it an ideal choice for outdoor use.

With a resonance frequency (Fs) of 39 Hz and a total quality factor (Qts) of 0.23, this loudspeaker is designed for a recommended load of 120 liters tuned at 40 Hz, promoting precise and deep sound reproduction in the low frequencies.
Its maximum linear excursion (Xmax) of 13 mm allows a significant displacement of the cone without noticeable distortion, thus guaranteeing a faithful and powerful reproduction of the bass. Its frequency response extends from 39 Hz to 1 kHz, which makes it mainly intended for subwoofer or low frequency applications in multi-way systems.
In addition, with a sensitivity of 96.8 dB at 1W/1m, it ensures high efficiency, thus reducing the need for amplification to achieve a significant sound level.
