The 18 SOUND 15LW2400-8 is a cutting-edge 15-inch subwoofer, engineered for high-performance audio applications. Designed to deliver clean, linear, and undistorted low-frequency sounds at very high power levels, this subwoofer is ideal for professional audio systems. It's crafted with a weather-protected, fiberglass-reinforced cellulose cone and employs advanced technologies like Double Silicon Spider (DSS) and Double Demodulating Rings (DDR) to ensure improved control, linearity, and reduced distortion. The 100 mm Interleaved Sandwich Voice coil (ISV) provides uniform motive drive and excellent heat dissipation, while its optimized magnetic structure reduces weight without compromising on power. This subwoofer is perfect for those seeking uncompromised audio quality in a durable, high-power design.
