High volume sound reinforcement systems for fairs, arenas, and stadiums require large amounts of clean, clear midrange output. In addition, many public address applications expose loudspeakers to severe environmental conditions. For maximum projection of speech and limited-bandwidth program material, choose a weather-resistant commercial sound PA driver and match it to an appropriate reentrant horn.
Most PA drivers feature diaphragms constructed of phenolic-impregnated linen, which yields a nearly indestructible material that is also extremely low in coloration and distortion. A 70 volt transformer facilitates practical and economical distribution of multiple PA horn loudspeakers, especially over long cable runs.
