Overview

B&C 18TBX100-4 18" Woofer 4 Ohm

The industry-standard B&C Speakers 18TBX100-4 features a 1" long/4" diameter copper wire voice coil with high thermal capability, and a ventilated magnet assembly, both of which contribute to low power compression. A very low distortion figure is obtained using a double spider design and dual demodulation rings in the magnetic path. The 18TBX100-4 is fortified by a proprietary water-proof cone treatment that facilitates safe use in adverse climatic conditions. This benchmark pro subwoofer driver is found in many famous manufacturers' well-established loudspeaker enclosures.
