Overview

B&C 18TBW100-4 18" Professional Subwoofer 4 Ohm

B&C's 18TBW100-4 18" professional woofer features 3,000 watts of continuous program power capacity, thanks to its 4" split winding copper voice coil. A frequency response of 30 to 1,000 Hz and 57 mm of peak-to-peak excursion (before damage) combine to make this one of the top woofers in its class. The 18TBW100-4's double silicone spider with optimized compliance keeps the driver controlled, while the ventilated voice coil gap reduces power compression. Low distortion is achieved by using an aluminum demodulating ring in the driver's magnetic circuit. Great performance is realized in vented boxes as small as 7 cu. ft.
