B&C 18 RBX 100 4 LF Driver
- 2000 W Continuous power handling
- 4.0 in (100 mm) Voice coil diameter
- Ferrite Magnet material
The new B&C 18RBX100
anchors our ferrite subwoofer line, and features an all new FEA optimized motor
structure. 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 as small as 120 litres.
