Product Details

Cerwin-Vega CVA-121X 21" Active Powered PA Subwoofer 1200W RMS with Stroker Woofer

The CVA-121 system offers tremendous power output and exceptional low frequency response. A key engineering challenge in the development of the CVA-121 was to maintain woofer control from a system able to deliver such extreme excursions and high SPL. The answer? Cerwin-Vega's innovative Stroker® Technology, which utilizes a threespider driver design to optimize cone excursion and voice coil efficiency. Stroker® provides a pair of double inverted spiders to control linearity and maintain smooth excursion. While a third spider provides another plane of support for speaker movement. The third spider also keeps the surround from pulling the cone unevenly, dramatically improving voice coil and magnetic gap alignment at the system's extreme output. Cerwin-Vega engineers even utilized a unique and striking cast aluminum grille that doubles as a speaker heat sink, enabling these woofers to play longer and harder than anything else in their class.

Matched to this woofer is a powerful, built-in 1,200 watt (2,400 watt peak), high-efficiency Class-H amplifier. The CVA-121 amplifier includes a unique onboard parametric equalizer that allows for added adjustment of gain, frequency and Q for customized performance options. This allows users to dial in the correct sub response for each venue. Users can bump frequencies that need more emphasis or cut off ending frequencies that occur from room corner loading or wall boundary conditions. Integrating all these technologies allows the CVA-121 to deliver best in class low frequency output from a 21" speaker, but has a footprint more like an 18" box. The result of all this integration is power, upgradeability and improved portability.

Unleashing all this power has never been easier thanks to a complete array of connection and mounting options. First, XLR and quarter inch connectors allow for balanced and unbalanced operation, and flexible setup while using a wide variety of cables and configurations.

While Master/Slave output connectors allow users to daisy-chain multiple CVA subwoofers. Finally, three top-mount 35 mm pole sockets and matched mounting accessories, provide for flexible full range system configurations.

Protecting your investment is solid 18 mm hardwood construction, available in either durable Coolex® polyurethane paint or high grade Carpet finish. Bottom line; the CVA-121 Active Subwoofer will provide you exceptional performance in a package much smaller and easier to use than you have ever seen before.
