The white EVF-1181S Single 18” Front-Loaded Outdoor Subwoofer System from Electro-Voice is a high power, front-loaded bass element that can be used in a variety of applications where high quality sound reinforcement is required. It utilizes the EVS18SB 18” woofer developed using FEA optimization for motor, suspension, and electrical design to ensure very low distortion and maximum intelligibility at high SPL levels. Its features make it suitable for many fixed install applications, including applications with full exposure to outdoor elements.
The trapezoidal enclosure is constructed out of weather resistant birch, and coated with fiberglass for maximum protection from outdoor elements. The acoustic and rigging design allows for vertical and horizontal clusters to be built using any combination of loudspeakers from the entire EVF & EVH series. The input panel features a Phoenix-style connector and includes a gland-nut cover plate.
