KI-398-RGL

The Klipsch KI-398-RGL is a full-range 22.5-degree trapezoidal design ideally suited for use as a vertical line array in a behind-the-screen cinema system. The loudspeaker has incredible output capability, featuring a 15-inch high-excursion cast-frame woofer, a large-format 3-inch titanium compression driver, and an internal high-current full-range crossover. The KI-398-RGL utilizes a modified Tractrix horn that provides a well-defined 90 x 50 degree dispersion pattern for optimum coverage and smooth off-axis response, with maximum output of 126 dB continuous, 132 dB peak. All components are housed in a rugged birch plywood enclosure with aesthetically profiled edges and a durable finish. Side-plates are available for vertical line array configurations.
