Overview

The B&C 18NBX100-8 is an 18" super woofer designed for high-performance audio applications, offering a continuous program power capacity of 2400 W and equipped with a 100 mm (4 in) copper voice coil for exceptional audio output. Covering a frequency range of 35 Hz to 1000 Hz, it delivers robust low-frequency response.

This super woofer features a triple roll surround, radial cone shape, and an optimized neodymium magnet assembly. The ventilated voice coil gap ensures reduced power compression even at high volumes. Additionally, the woofer incorporates an aluminium demodulating ring to minimize distortion. With parameters such as a recommended enclosure size of 200.0 dm3 (7.1 ft3) and tuning frequency of 35 Hz, the B&C 18NBX100-8 is engineered for impactful and accurate bass reproduction in professional audio setups.
