Manual 

The B&C 15RBX100 anchors the ferrite subwoofer line, and features an all new FEA optimized motor structure.

2000 W continuous program power capacity

100 mm (4 in) copper voice coil

40 - 3000 Hz response

94 dB sensitivity

Aluminium demodulating ring allows a very low distortion figure

Double silicone spider with optimized compliance

The 25mm high, 4" (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.
