EVID Series Premium Surface Mount Speaker System Perfect for a variety of environments where full-range audio is needed but space is limited: restaurants, bars, bistros, department stores, and out door venues. Offering the bass response of a much larger speaker, dual 4-inch woofers make the 4.2 a phenomenal performer. The one-inch waveguide coupled titanium tweeter delivers controlled clean mids and highs. Combine it with the 12.1 subwoofer for an amazing listening experience. Full system protection and EV's unique Strong-Arm Mount(TM) (SAM(TM)) make the EVID 4.2 a solid choice in any environment.
