PROFESSIONAL AUDIO - CERWIN VEGA ACTIVE SERIES
CVA-121
21" ACTIVE SUBWOOFER
Description:

The CVA-121 is a flagship 21-inch active subwoofer with tremendous power output and exceptional low-frequency response. The custom designed 21-inch driver uses the legendary Cerwin-Vega Stroker® three spider technology for maximum cone excursion and voice-coil efficiency.

The CVA-121 features built-in amplification for a fully integrated solution with an authoritative 1200 watts of continuous output and 2400 watt peaks. A unique and striking cast aluminum grille doubles as a heat-sink to minimize power compression and optimizing driver performance.

The CVA-121 is constructed of hardwood with the option of a Coolex® polyurethane paint or high-grade black carpet finish, in a compact enclosure design that has the footprint of a standard 18-inch subwoofer.

This high-performance active sub features XLR and 1/4” TRS connectors, Master/Slave output connectors for daisy-chaining multiple CVA subwoofers using a single signal, and a versatile onboard parametric equalizer that allows for the adjustment of the gain, frequency, and Q for perfecting your bass performance. A top-mounted 35 mm pole socket accommodates a satellite speaker for full range performance, and removable casters add to the sub’s portability.
