18-inch single front-loaded bass element subwoofer can be used in variety of applications where high quality sound reinforcement is required in a lightweight package. It utilizes the EVS18SB 18-inch woofer used FEA optimization for motor, suspension and electrical design for very low distortion and maximum intelligibility at high SPL levels. The EVF-1181S features make it professional loudspeaker for any fixed install application. The trapezoidal enclosure is constructed out of weather resistant birch and coated with EVCoat for maximum protection from the 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 an assortment of full-range, low frequency and subwoofer loudspeakers, it gives the tools to maximize flexibility of system design. The innovative input panel provides choice of Phoenix style connector or the ability to add dual NL4 type connector cover plate or gland nut cover plate (for weatherizing applications). An available 70.7/100V transformer kit simply mounts to the input panel for use in distributed systems.
