CX800 is a high-output subwoofer boasting a 2,000 W Class D amplifier and built-in DSP settings for enhanced efficiency. Two premium 18" neodymium extended low-frequency transducers drive performance down to 25 Hz. State-of-the-art 5.3" voice coils, triple silicon spiders, and large displacement suspension systems allow 70 mm of excursion before damage with 28 mm of linear Xmax. An aluminum demodulation ring flattens both impedance and phase response and significantly reduces distortion. CX800 is constructed from high-grade, void-free Baltic birch for a lightweight but durable package protected by a tour-grade, high-impact EXL Polyurea finish. Modules are cardioid-arrayable and designed for versatility in a wide range of mobile and installed applications.
