At the heart of the CVA-121 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 cast aluminum grille 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 1200-watt (2400 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 maximized control and output. Integrating all these

technologies allows the CVA-121 to deliver best-in-class low frequency output from a 21-inch speaker
