Cerwin Vega 21 Inch Subwoofer

[Yogprasad Moneta]

Thehome theater market sees subwoofers growing smaller and smaller, but in the professional market things are quite different. To perfectly illustrate this, Cerwin Vega has announced that it is introducing a new 21-inch subwoofer to its professional line. OK, the cat's out of the bag - this is a sound reinforcement subwoofer, and not intended for home theater use - but WOW, 21 inches - that's pretty big!

To date, anything over 18-inches has been impractical due to issues with cone stiffness and breakup. A 21-inch subwoofer is a challenge and it seems Cerwin Vega! has broken through some of the limitations and made a product that can work well for professional sound reinforcement use.

The Cerwin-Vega Active Series consists of twomodels, the CVA-121 and CVA-118, named in accordance with their respective drivers. Both subs are actually pretty tame in terms of size, given their 18-inch and 21-inch driver complement. Both subs are active with built-in amplifiers and have functional cast aluminum grills which double as heat-sinks tominimize power compression and maximize driver performance.

In addition to the expected XLR and 1/4" connectors, the CVA subwoofers have Master/Slave outputconnectors that allow for multiple compatible subs to be connected in series (with no loss of resolution or signal since they are active). The subwoofers also feature a 35 mmpole-mount socket to accommodate a "satellite" speaker for full rangeperformance and the CVA-121 includes removable steel casters so you can move it without a forklift. Both subs are constructed of 18 mmhardwood and finished with either durable Coolex polyurethanepaint or a high-grade black carpet finish.
