Cerwin Vega CVi-218S Passive Dual 18inch Subwoofer

Cerwin-Vega made its bones on bass. Big, bumping bass, back before bass was ever called bumping. The CV identity is awash in bass. Big, beautiful bass. The CVi-218S (Contra-Sub) is a portable, dual eighteen inch dedicated subwoofer system designed to extend and supplement the low frequency extension of CVi full range systems in live music and playback applications. The CVi-218S features two high power, cast frame eighteen inch transducers with 3 voice coils for extended use during high SPL applications. Steel handles and pole mount cup are also featured for use as a base for pole mounted full range systems. This configuration allows the two drivers to work together in the same acoustic space to reduce distortion components caused by driver mechanical non-linearity when the system is driven at high levels. The result is cleaner, smoother low frequency reinforcement at higher SPL levels.
