12-inch single two-way full-range loudspeaker system can be used in variety of applications where high-quality sound reinforcement is required in a compact and lightweight package. It utilizes the ND2B, a high output 2-inch titanium compression driver coupled to constant directivity 90° x 40° waveguide. The SMX2121 12-inch woofer was developed using FEA optimization for motor, suspension and electrical design to ensure very low distortion, high efficiency and maximum intelligibility at high SPL. The crossover uses steep 24dB/octave slopes with equalization for very smooth response in the vocal range, linear off-axis response and a protection circuit for long-term reliability. The EVF-1122S/94 features make it ideal for many fixed-install applications including applications with full exposure to outdoor elements. The trapezoidal enclosure is constructed of weather-resistant birch and coated with fiberglass for maximum protection from extreme outdoor elements. The unique acoustic and rigging design allows for vertical and horizontal clusters to be built using any combination of loudspeakers from the entire EVF series. With seven horn patterns to choose from along with an assortment of low-frequency and subwoofer loudspeakers, you have the tools to maximize flexibility of system design. The innovative input panel provides a choice of Phoenix style connector or the ability to add a dual NL4-type connector cover plate or gland-nut cover plate (for weatherizing applications). An externally accessible jumper selects passive or active operation. An available 70.7/100V transformer kit may be easily mounted to the input panel for use in distributed systems.
