B&C Speakers 15-inch LF Driver Audio Woofer Cone

The B&C Speakers 15CL76 is a rugged and high-performance 15-inch low-frequency driver engineered for professional audio systems, especially in demanding and outdoor environments. Built to deliver 400W RMS and 800W peak power, it features a 3-inch copper voice coil mounted on a glass fibre former, ensuring excellent heat resistance and mechanical stability. Its ventilated voice coil gap minimizes power compression and thermal buildup, allowing consistent performance even under heavy use. With a frequency response of 40 Hz to 3000 Hz and a sensitivity of 98.5 dB, the 15CL76 offers efficient and powerful sound reproduction. The waterproof-treated front cone adds durability, making it ideal for outdoor PA systems and installations exposed to the elements. Internally, the woofer is optimized for low-frequency output with a resonant frequency of 42 Hz, DC resistance of 5.1 ohms, and a Qts of 0.33, making it well-suited for vented enclosures. Its Equivalent Volume (Vas) of 135 dm³ (4.8 ft³) and piston area of 855 cm² enable strong air displacement, while the 2.9% efficiency, 8.5 mm excursion, and 21 Tm motor force ensure deep, controlled bass. The design incorporates a triple roll surround and exponential cone shape for smooth excursion and acoustic control. A neodymium inside slug magnet, single spider, and straight pole structure provide mechanical stability and precision. For optimal performance, it is recommended to use the woofer in a 100 dm³ (3.53 ft³) vented enclosure, tuned to 47 Hz. Mounting is straightforward thanks to its standardized dimensions: an overall diameter of 15.31 inches, baffle cutout of 13.9 inches, bolt circle of 14.72 inches, and a depth of 6.73 inches with a flange thickness of 0.43 inches. The driver occupies 0.15 ft³ of internal volume and weighs 8.38 lb. For transport, it ships in a compact box measuring 16.73″ (Length) × 16.73″ (Width) × 8.82″ (Height) with a total shipping weight of 11.24 lb. Altogether, the B&C 15CL76 stands out as a powerful, efficient, and weather-resistant woofer—perfect for professional sound systems that demand reliability, clarity, and punch.
