The R1 two-way full-range loudspeaker system is an all horn-loaded design using multilayer glass composite construction. The wide range, smooth frequency response and high efficiency of the R1 ensure excellent quality music reproduction and superb projection of clear intelligible speech with very low distortion. A weather-resistant mounting yoke is included for ease of installation. The R1 loudspeakers are available in two versions. The standard version is weather-ready, with a WeatherStopTM grille and stainless steel exterior. The BNG version, with black exterior and no grille, is more suitable for indoor applications. Five year limited warranty.
