Double 18" subwoofer

The CV-218B is a bass reflex subwoofer equipped with two 18″ woofers with 4″ voice coil. The CV-218B turns bass into an impressive low-frequency experience and complements the SE AUDIOTECHNIK CV-Line with its powerful and straight bass performance.

The dual 18″ subwoofer delivers up to 148 dB max SPL and extends down to 30 Hz. With long excursion, a continuous power handling of 1,700 W (6,800 W peak) and 104 dB sensitivity (1W/1m), the CV-218B subwoofer covers a wide dynamic range and can be combined with many SE speaker systems.

For safe and comfortable transport and setup, the CV-218B features four ergonomic handles on the sides. Anti-skid feet on the bottom provide essential stability.

Despite its comprehensive features, the CV-218B subwoofer blends unobtrusively into any design concept at the installation or event location. Due to its carefully thought-out design, the bass reflex subwoofer of the SE AUDIOTECHNIK CV-Line provides a noticeable and long-range bass foundation in any sound reinforcement situation.
