  • Model DSA Directional Speaker Array provides excellent voice and tone reproduction and is ideal for overcoming high levels of industrial noise.

    Design flexibility allows the user to combine up to four speaker arrays; each array will hold from two to six re-entrant speakers. Speakers have a 70º horizontal angle of dispersion, accommodating specific sound output patterns. Ideal for outdoor industrial plant warning, the Model DSA speaker array allows sound coverage to be customized to each site, preventing wasted sound level in and around the plant.

    Design flexibility allows the user to combine up to four speaker arrays; each array will hold from two to six reentrant speakers. Speakers have a 70 degree horizontal angle of dispersion, accommodating specific sound output patterns. (When vertical stacks are placed 90 degree apart, a 180 degree horizontal coverage is possible.)

    Model DSA mounting kits allow for multiple speaker arrays to be mounted on the same pole at 90 degree increments. The downward tilt can be adjusted by 15 degree. The mounting flexibility of this system allows the speakers to be pointed directly at a targeted area for more concentrated sound output.

    A DSA consists of a corrosion resistant aluminum frame with fiberglass projectors and stainless steel mounting hardware. Each speaker contains a high efficiency 100 watt driver.
