Description

• FEATURES : B&C 8NW51 is a compact yet powerful 8-inch mid-bass woofer. Delivers 400W program power with a 2-inch ventilated copper voice coil, ensuring efficient heat dissipation and reduced power compression. Operating across a 703000 Hz frequency range with 96.5 dB sensitivity, it features a neodymium ring magnet assembly and a shorting copper cap for enhanced high-frequency response. Its TWP-treated cone, waterproof on both sides, makes it ideal for demanding and outdoor audio environments.
• SPECIFICATIONS : The B&C 8NW51 is a rugged 8-inch mid-bass woofer designed for professional PA systems, offering 200W nominal and 400W program power at 8 ohms. It delivers clear, efficient sound with 96.5 dB sensitivity across a 703000 Hz range. Built with a 2-inch copper voice coil on a glass fibre former, it ensures precise control and heat resistance. Its TWP-treated waterproof cone and 7.7-ohm minimum impedance make it a reliable choice for both indoor and outdoor applications.
• PARAMETERS : The B&C 8NW51 is a precision-engineered 8-inch mid-bass woofer optimized for vented enclosures, with a resonant frequency of 74 Hz and a Qts of 0.17. It offers 2.4% efficiency through a 220 cm piston area and 11 dm Vas, supporting 6 mm excursion for solid low-end response. Its 28 g moving mass, 18.9 Tm motor force, and 0.4 mH inductance ensure fast, controlled output, while a high EBP of 389 Hz makes it ideal for extended frequency use in professional PA systems.
• DESIGN : The B&C 8NW51 features a double roll surround and exponential cone shape for enhanced excursion and sound dispersion. It uses a neodymium ring magnet and a single spider for lightweight, responsive performance. The T-pole design ensures magnetic symmetry, while the TWP-treated cone is waterproof on both sides, making it suitable for rugged and outdoor environments.
• MOUNTING & SHIPPING INFO : The B&C 8NW51 has an overall diameter of 8.8 inches, with a bolt circle of 8.3 inches and a baffle cutout of 7.4 inches. It measures 4 inches deep, with a 0.4-inch flange and gasket thickness, and occupies 0.04 ft of air volume. The woofer weighs 6.72 lb, and ships in a 10.04 10.04 5.91 box, with a shipping weight of 7.72 lb.

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 703000 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 woofers 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 cm 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 ft 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.
