The CVi-218S 18" Passive Portable PA Speaker from Cerwin-Vega is a portable, dual 18" 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 speaker features 2 high power, cast frame 18" transducers with a 3" voice coil for extended use during high SPL applications. Steel handles and a 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.
PEPT Film (Mylar) compression driver provides natural sounding instruments and vocals and the Hemi-Conical Waveguide (80° x 50°) gives smooth on and off axis frequency response.
The CVi-218S uses a unique inverted woofer design that boasts two high power 18" transducers with 3" voice coils. These contrary-loaded drivers effectively cancel mechanical and magnetic distortions when driven to high SPLs
An 18 gauge, perforated steel grill protects the entire front of the enclosure. The polypropylene fiber covered internally braced structural wood housing is durable, light, and strong.
The CVi-218S finds application in outdoor stages, portable live sound PA, auditoriums, drum monitor sub, DJ system PA, and clubs
