Earthshaking bass from the company that invented it.

The CVA-121 is a flagship 21" 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 subwoofer 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 subwoofer speakers 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.

Comments about Cerwin-Vega CVA-121 21" Active Subwoofer:

Massive Power, small footprint, tight clean bass. but make no mistake unless you spend 5 or 6 days a week at the gym it is a 2 man operation to transport these monsters to a gig and get them on the stage. The built in DSP and crossover actually improved the power output and sound quality to the JBL PRX525s I now top them with. I would compare them to other powered subs from other brands but without referring to Stadium speakers these things have no equal! however they are overkill for all but large venues, but I like overkill it lets me run lower volume levels which equals less stress on the gear and a longer useable lifespan. At my primary gig I run less than half volume on both subs and the JBLs. Cerwin-Vega hit a home run with these but if your largest venue is less than 500 people I might consider the 18" or 15" version Cerwin-Vega offers simply for ease of transportation. I can not say enough good things about these subs if you want Massive tight bass you can not go wrong with these and they cost less than subs that do not perform as well! Well worth the extra weight and money spent!

Comments about Cerwin-Vega CVA-121 21" Active Subwoofer:

I own a DJ business in the Dallas area. I own Two of these Monster subs and I tell you Getting the dance floor Bumpin' is not a problem. At full volume on my mixer they are solid with no distortion. Worth every penny. Heavy though.
