The R2-474Z full-range loudspeaker system is engineered to provide quality, long throw full-range sound projection in a variety of outdoor and indoor applications. Its wide, smooth frequency response and high efficiency ensures high-fidelity music reproduction along with superb projection of clear, intelligible speech at very low distortion.

The R2-474Z is an all horn-loaded tri-axial design using precision waveguides manufactured by Community of hand-laminated fiberglass. The outer enclosure forms a double wall construction with the internal bass horn, providing a completely weather-sealed chamber for the LF drivers. The mid/high frequency horn assembly is mounted in the mouth of the bass horn. A high quality passive crossover with dynamic driver protection is included. There is also a stainless steel mounting yoke included.

The result is a loudspeaker system that is extremely strong, non-resonant, weather-resistant, and easy to install.

All R-Series loudspeakers are protected by a 5 year limited component warranty and a 15 year limited enclosure warranty.
