B&C 15NDL88 - 15" 700W 8 Ohm Loudspeaker
The NDL88 series is perfectly balanced for the modern loudspeaker systems. 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. Impressive 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.
