Description

• FEATURES : The B&C 15CL76 is a durable 15-inch LF woofer designed for high-demand audio setups, delivering 800W program power with a 3-inch copper voice coil for heat resistance and longevity. It operates across a 403000 Hz range with 98.5 dB sensitivity, ensuring efficient output. Its ventilated voice coil gap reduces power compression and thermal buildup, making it ideal for professional PA systems and outdoor use.
• SPECIFICATIONS : The B&C 15CL76 is a powerful 15-inch LF woofer designed for high-output audio and outdoor use. It handles 400W nominal and 800W peak power with 98.5 dB sensitivity, covering a 40 Hz to 3000 Hz range. Featuring a 3-inch copper voice coil on a glass fibre former, it offers precise control through a 0.43-inch magnetic gap and 1.15 T flux density. Its waterproof front cone makes it ideal for professional PA systems in demanding environments.
• PARAMETERS : B&C 15CL76 woofer is optimized for low-frequency performance with a resonant frequency of 42 Hz and DC resistance of 5.1 ohms. Its Qts of 0.33 and EBP of 124 Hz make it well-suited for vented enclosures. With a Vas of 135 dm (4.8 ft) and a piston area of 855 cm, it offers strong air displacement and a 2.9% efficiency. Driver supports up to 8.5 mm excursion, powered by a 108 g moving mass and a Bl factor of 21 Tm, while its 1.3 mH inductance ensures smooth frequency response.
• DESIGN : The B&C 15CL76 woofer features a triple roll surround and exponential cone shape for enhanced excursion and acoustic control. It uses a neodymium inside slug magnet, single spider, and straight pole design for mechanical stability. The front cone is waterproof (WP-treated), making it suitable for outdoor use. It performs best in a 100 dm (3.53 ft) vented enclosure with a recommended tuning frequency of 47 Hz.
• MOUNTING & SHIPPING INFO : 15CL76 is a 15-inch woofer designed for easy integration into standard enclosures. It has an overall diameter of 15.31 inches, a baffle cutout diameter of 13.9 inches and a bolt circle diameter of 14.72 inches with a depth of 6.73 inches and flange thickness of 0.43 inches. Driver occupies 0.15 ft of internal volume and weighs 8.38 lb. For shipping, it comes in a box measuring 16.73 (Length) 16.73 (Width) 8.82 (Height) with a total shipping weight of 11.24 lb.

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 dm (4.8 ft) and piston area of 855 cm 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 dm (3.53 ft) 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 ft 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 wooferperfect for professional sound systems that demand reliability, clarity, and punch.
