This pair of EVID 4.2T Dual 4-Inch Surface Mount Speakers is ideal for indoor and outdoor applications requiring high-quality sound. The 4.2’s three-dimensional elliptic baffle symmetrically locates the 1” Ti high-frequency element with a Coherent Coverage Waveguide in front of it and between the 4” low-frequency drivers. This careful shaping, location, and 10° splaying of the LF units provide coverage control by the resulting line array. The curved grille features built-in weather resistance and a hidden leash for safety.
