B&C Speakers 10NSM76-8 10-inch Sealed Neodymium Midrange Driver — 8 Ω, 400 W RMS / 800 W Max

Overview: The B&C Speakers 10NSM76-8 is a sealed-back, narrow-bandwidth midrange driver designed for pro audio applications where low distortion and high sensitivity are required. It features a cast aluminium sealed chassis, a high-strength neodymium motor and a large internal volume to improve low-frequency behavior. Large aluminium voice coils combined with carefully chosen suspension and cone materials deliver strong power handling and exceptional sensitivity. Key Highlights: - 800 W continuous program power capacity - 76 mm (3 in) aluminium voice coil - Frequency response: 235 - 3500 Hz - Sensitivity: 100 dB - Ideal for Direct Radiation and Horn Loaded Midrange applications Electrical / Acoustic Specifications: - Nominal Diameter: 250 mm (10.0 in) - Nominal Impedance: 8 Ω - Minimum Impedance: 7.0 Ω - Nominal Power Handling: 400 W - Continuous power handling: 800 W - Sensitivity (1W/1m): 100.0 dB - Frequency Range: 235 - 3500 Hz - Flux Density: 1.6 T Voice Coil and Motor: - Voice Coil Diameter: 76 mm (3.0 in) - Winding Material: Aluminium - Former Material: Glass Fibre - Winding Depth: 11.0 mm (0.45 in) - Magnetic Gap Depth: 9.0 mm (0.35 in) Mechanical / Mounting: - Overall Diameter: 291 mm (11.46 in) - Bolt Circle Diameter: 274 mm (10.79 in) - Baffle Cutout Diameter: 234.0 mm (9.21 in) - Depth: 130 mm (5.12 in) - Flange and Gasket Thickness: 12 mm (0.47 in) - Air Volume Occupied by Driver: 5.0 dm3 (0.18 ft3) Weight & Shipping: - Net Weight: 4.55 kg (10.03 lb) - Shipping Units: 1 - Shipping Weight: 5.45 kg (12.02 lb) - Shipping Box: 360 x 360 x 200 mm (14.17 x 14.17 x 7.87 in) Design Details: - Surround Shape: Accordion - Cone Shape: Radial - Magnet Material: Neodymium Ring - Spider: Single - Pole Design: T-Pole - Woofer Cone Treatment: WP (Waterproof Front Side) Application Notes: Built to simplify cabinet assembly while improving thermal transfer to the air, the NS M series sealed midranges are tailored for low distortion at a given output. The combination of a sealed cast aluminium basket, a powerful neodymium motor and a large voice coil makes the 10NSM76-8 suitable for demanding midrange duties in both direct radiation and horn-loaded systems.
