B&C 19RS115 M 19 inch 2000W Neodymium Subwoofer Driver, 4 ohm, Spring Terminals
The B&C 19RS115 M is a 19 inch neodymium subwoofer driver rated at 2000W AES and 4000W programme power. This 4 ohm version has push-button spring terminals.
A four-layer 116 mm voice coil works with a ventilated magnetic gap and an aluminium demodulating ring. The suspension combines a triple-roll surround with a double silicone spider, and the cone is treated on both sides for moisture resistance.
B&C specifies 96.9 dB sensitivity, a 30-1000 Hz frequency range and 23.3 mm Xmax for this impedance version. Check enclosure suitability and mounting dimensions before installation.
