The EVID 3.2 produces sound that defies its small size. It is loaded with dual, 3.5-inch, low-frequency drivers and a .75-inch, Ti-direct radiator. Its unobtrusive profile is ideal for background music and paging support in a variety of environments such as offices, retail stores, and restaurants. Coupled with the EVID 12.1 subwoofer, two to four EVID 3.2 speakers can deliver amazing SPL levels to foreground music.
