When people think of Cerwin-Vega Mobile, what usually pops up in their minds is our signature red rubber surround that has been in existence for 60 years! We continue that heritage with the introduction of our brand new VEGA series subwoofers. An all-new design and robust proprietary stamped cast VEGA basket is the foundation for the new VEGA series subwoofer. Couple that with a parabolic one piece stamped carbon fiber polypropylene and a high-power single stacked motor structure, some serious boom will be protruding from your trunk! For installation ease, a brand new integrated impedance selector feature has been added to VEGA series subwoofers on to keep system wiring simple! The signature red santoprene surround now incorporates matching red double stitching to complete the finish of the latest rendition of the new VEGA series subwoofers.
