B&C 12NBX100-4 12" Professional Neodymium Woofer 2000W 4-Ohm
- The B&C Speakers 12NBX100-4 high efficiency 12" woofer uses an FEA computer-designed neodymium magnet assembly, resulting in an extremely lightweight (only 17.6 lbs.) yet powerful professional speaker.
- The 12" speaker's cast aluminum basket is designed to effectively dissipate heat during demanding use at full power, reducing power compression. Usefully lightweight thanks to its high-energy neodymium magnet, the 12NBX100-4 is recommended for compact two-way pro speaker systems in which power is limited to 1,000 watts RMS or 2,000 watts program.
