B&C 12NDL88 12-Inch Speaker Driver - 700W RMS, 4 Ohm, Spade Terminals

The B&C 12NDL88 12-Inch Speaker Driver (4 Ohm) Speaker Driver is perfectly balanced for the loudspeaker systems of today. Incorporating a high temperature neodymium magnet inside the 3.5" (88mm) voice coil reduces the amount of steel needed in the motor structure, saving cost and weight. Unexpected low frequency output and midrange extension to meet with almost any driver for two way applications is the hallmark of this new performance-oriented woofer line from B&C Speakers. Do more, with less, with the NDL88 series.
