B&C 18RBX100 18-Inch Speaker Driver - 1000W RMS, 8 Ohm

The B&C 18RBX100 18-Inch Speaker Driver anchors B&C's ferrite subwoofer line, and features an all new FEA optimized motor structure. The 25mm high, 4-inch (100mm) diameter copper wire voice coil is combined with a laminated double silicone spider, water resistant curvilinear cone and triple roll surround, for even more excursion and linearity.
The corrosion resistant motor structure incorporates an aluminum demodulation ring that effectively controls inductive rise as well as harmonic and intermodulation distortion. This subwoofer can be used for a wide variety of applications, including compact vented enclosures as small as 120 litres.
