The OS80-B is an outdoor loudspeaker designed with a weather-resistant enclosure. It features a 12-inch/1.4-inch coaxial driver paired with an 80° conical Synergy Horn, delivering sound pressure levels exceeding 130 dB. The integrated Synergy crossover network ensures precise phase alignment across frequency bands, resulting in reduced off-axis frequency response distortions and consistent audio clarity over distance. The unit weighs 51 pounds and includes a heavy-duty aluminum mounting bracket with an adjustable angle strap.

The speaker incorporates Sentinel high-frequency driver protection circuitry, a multistage limiter that prevents damage from overloads without affecting normal audio dynamics. The OS80-B is compatible with DNA amplifiers and processors for optimized performance via advanced digital signal processing (DSP). This model is intended for use in outdoor environments such as sports venues, recreational parks, public gathering areas, and aquatic facilities.
