B&C Speakers 8NW51 8-inch Neo Mid Bass Woofer Cone TWP Waterproof Both Sides LF Drivers 2" Ventilated Copper Voice Coil Gap 200 Wrms 400 Watts Peak Audio PA System 8 Ohm

The B&C 8NW51 is a compact yet high-performance 8-inch neodymium mid-bass woofer crafted for professional PA systems that demand clarity, durability, and efficiency. With a 200W nominal and 400W program power capacity at 8 ohms, it delivers robust output across a 70–3000 Hz frequency range, supported by a 96.5 dB sensitivity that ensures powerful sound even at lower input levels. At its core lies a 2-inch ventilated copper voice coil wound on a glass fibre former, designed to reduce power compression and maintain thermal stability during extended use. The woofer’s TWP-treated cone, waterproof on both sides, makes it exceptionally suited for outdoor and high-humidity environments. Structurally, it features a double roll surround and exponential cone shape for enhanced excursion and sound dispersion, while its neodymium ring magnet, single spider, and T-pole design contribute to lightweight responsiveness and magnetic symmetry. Performance-wise, the 8NW51 is optimized for vented enclosures, with a resonant frequency of 74 Hz, Qts of 0.17, and a high EBP of 389 Hz, indicating its capability for extended frequency applications. Its 220 cm² piston area, 6 mm excursion, and 2.4% efficiency are driven by a 28 g moving mass, 18.9 Tm motor force, and 0.4 mH inductance, ensuring fast, controlled bass response. For installation, the woofer measures 8.8 inches in diameter, with a bolt circle of 8.3 inches, baffle cutout of 7.4 inches, and a depth of 4 inches, occupying just 0.04 ft³ of air volume. It weighs 6.72 lb and ships in a compact 10.04″ × 10.04″ × 5.91″ box, with a total shipping weight of 7.72 lb, making it both powerful and practical for mobile and fixed sound systems.
