B&C Speakers 15DS115-4 15-inch Neodymium LF Driver — 4 Ohms, 1600 W / 3200 W Pro Audio (Motorcycle/Car)

Overview: The B&C Speakers 15DS115-4 is a 15.0 in (380 mm) professional low-frequency driver built with a neodymium magnet for high force factor and controlled linear excursion. It is designed for heavy-duty pro audio use and is suitable for installations in vehicles such as motorcycles and cars where a compact, high-performance woofer is required. Key highlights: 3200 W continuous program power capacity; 1600 W nominal power handling; 96 dB sensitivity (1 W/1 m); frequency response 35–1000 Hz; 60 mm peak-to-peak excursion before damage. The transducer uses a 116 mm (4.5 in) four-layer aluminium voice coil, a ventilated voice coil gap to reduce power compression, and an aluminium demodulating ring to minimize distortion. A double silicone spider provides optimized compliance for improved linearity. Electrical and acoustical specifications: Nominal Diameter: 380 mm (15.0 in). Nominal Impedance: 4 Ω.
