Cerwin-Vega CVA-121 - Manual

he 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.
