Continuous power handling
Voice coil diameter
Magnet material
Over the last several years, B&C has pushed neodymium magnet woofer performance to the next level. The deep, 3" (76mm) diameter voice coil utilized in the 10NW76 provides increased power handling and more overall output. A proven B&C suspension system combines a triple roll surround and single spider for superior, reliable Xmax and balanced output. An aluminium demodulation ring keeps distortion low, while the deeper, high power voice coil is cooled using a ventilated voice coil gap. Extreme performance and reliability, excellent value.
