Product Description
The R2-474Z is an all-horn-loaded triaxial design using precision Community waveguides of hand-laminated fiberglass. The outer enclosure forms a double-wall construction with the internal bass horn, creating a fully weather-sealed chamber for the LF drivers, while the mid/high-frequency horn assembly is mounted in the mouth of the bass horn. Its wide, smooth frequency response and high efficiency support high-fidelity music and clear speech at very low distortion. A high-quality passive crossover with DYNA-TECH dynamic driver protection is included, along with a weather-resistant mounting yoke for straightforward installation and aiming. A 70 Hz high-pass filter is recommended, and a digital system processor is available as an option.
