Product Description

The CVA121 offers tremendous power output and exceptional low frequency response.
The CVA121 represents an industry milestone, as it is the first 1200 watt, 21 inch active subwoofer. At the heart of the CVA121 is Cerwin Vega’s patented Stroker Technology, which utilizes a three-spider driver design to optimize cone excursion and voice coil efficiency. Even the unique and striking cast aluminum grille doubles as a speaker heat sink, enabling these woofers to play longer and harder than anything else in their class.

Cerwin Vega CVA121 Subwoofer Features:

  • Custom 21 inch Legendary Stroker technology using a three spider driver design
  • Built-in system amplification optimized for the 21 inch woofer
  • Master/ Slave Output allows for daisy-chaining multiple subs reduces cable connections
  • On-board Parametric Equalizer allows control of performance output by control of the gain, frequency, and Q
  • Cast Aluminum Grille protects the woofer and acts as a heatsink by reducing power compression
  • Rugged Hardwood Enclosure with removable casters
Matched to this woofer is a powerful, built-in 1200 watt (2400 watt peak), high-efficiency Class H amplifier. The CVA121 amplifier includes a unique onboard parametric equalizer that allows for added adjustment of gain, frequency and Q for maximized control and output. Integrating all these technologies allows the CVA121 to deliver best in class low frequency output from a 21 inch speaker, but has a footprint more like an 18 inch box. The result of all this integration is power, upgradeability and improved portability.
The CVA121 has a complete array of connection and mounting options. XLR and quarter inch connectors allow for balanced and unbalanced operation, accommodating a wide variety of cables and configurations. Master/Slave output connectors allow users to daisy chain multiple CVA subwoofers for precise control from the master unit. Finally, three top-mount 35 mm pole socket and matched mounting accessories, provide for flexible full range system configurations.
Protecting your investment is solid 18 mm hardwood construction. Bottom line; the CVA121 Active/Powered Subwoofer will provide you exceptional performance in a package much smaller and easier to use than you have ever have seen before.
