The black EVF2151D Dual 15" Front-Loaded Bass Element 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. The system utilizes two 15" woofers, developed using FEA optimization for motor, suspension, and electrical design to ensure very low distortion and maximum intelligibility at high SPL. The system features a Phoenix-style connector and CDG gland-nut on the input panel. It also features an externally accessible jumper that lets you select passive or active operation.
The system is enclosed in a trapezoidal enclosure that is constructed of weather-resistant birch, and coated with EVCoat for protection from the elements. For further protection against elements, this system comes with a fiberglass finish. The acoustic and rigging design allows for vertical and horizontal clusters to be built using any combination of loudspeakers from the entire EVF and EVH series. Unlike the standard version, this system features stainless steel grille with hydrophobic cloth.
