B&C Speakers 12NDL76-8 12-inch Neodymium Woofer — 8 Ohms, 400 W / 800 W, 50-2000 Hz, 100 dB

Overview: The B&C Speakers 12NDL76-8 is a 12.0 in (320 mm) pro audio woofer built around a lightweight neodymium motor for high output applications in car and motorcycle audio systems. It delivers excellent sensitivity (100 dB) across a wide frequency span (50 - 2000 Hz) and combines strong power handling with a ventilated design to reduce thermal compression. Power & Voice Coil: Nominal power handling: 400 W. Continuous power handling: 800 W. Program power capacity: 800 W continuous. The driver uses a 76 mm (3.0 in) aluminium voice coil with a 19.0 mm (0.75 in) winding depth and a ventilated gap to improve heat dissipation and maintain consistent performance under load. Magnet & Motor: Magnet material: Neodymium — providing a compact, powerful motor assembly. Magnetic gap depth: 10.0 mm (0.4 in). Flux density: 1.25 T. The neodymium motor keeps weight low while delivering strong magnetic flux. Cone & Surround: Cone shape: Exponential. Surround shape: Double Roll. Inside slug spider: Single. Pole design: Straight Pole. Woofer cone treatment: None. Spider and suspension geometry are engineered for controlled excursion and stability. Recommended Enclosure: Recommended enclosure volume: 42.0 dm3 (1.48 ft3) with a tuning of 65 Hz. Air volume occupied by driver: 2.5 dm3 (0.08 ft3). Key Electrical / Acoustic Specs: Nominal impedance: 8. Minimum impedance: 6.2. Sensitivity (1W/1m): 100.0 dB. Frequency range: 50 - 2000 Hz. Voice coil winding material: Aluminium. Former material: Glass Fibre. Thiele/Small & Performance Parameters: Resonance frequency (Fs): 50 Hz. Re: 5.3. Qes: 0.21. Qms: 4.2. Qts: 0.2. Vas: 73.0 dm3 (2.5 ft3). Sd: 522.0 cm2 (80.9 in2). 4.3 %. Xmax: 7.0 mm. Xvar: 6.5 mm. Mms: 53.0 g. Bl: 20.1 Txm. Le: 1.0 mH. EBP: 238 Hz. Design Notes: The driver features a ventilated voice coil gap to reduce power compression and improve thermal performance. The construction uses glass fibre former and aluminium winding for reliable high-power operation. Mounting & Shipping Information: Overall diameter: 315 mm (12.4 in). Bolt circle diameter: 298 mm (11.7 in). Baffle cutout diameter: 283.0 mm (11.1 in). Mounting depth: 141 mm (5.5 in). Flange and gasket thickness: 14 mm (0.55 in). Net weight: 3.9 kg (8.6 lb). Shipping units: 1. Shipping weight: 4.8 kg (10.58 lb). Shipping box dimensions: 360 x 360 x 200 mm (14.17 x 14.17 x 7.87 in). This woofer is designed for pro-level car and motorcycle audio installations where high sensitivity, compact motor weight, and robust power handling are required.
