The white Control 31 Speaker from JBL utilizes high-power components, computer optimized horn, and a complex network to achieve a smooth, powerful high-fidelity performance, extended bandwidth, and a well-controlled and defined coverage from a compact loudspeaker. The Control 31 features a 10" low-frequency driver with a pure butyl rubber surround, 2" high-temperature fiberglass voice coil for high sensitivity, high-output capability, and stability. The high-output, high-frequency compression driver has a unique patented design, high-temperature polymer diaphragm, and fluid-cooling for high-output levels with low distortion. This passive speaker has a 250W capability plus a 150W transformer for 70V or 100V distributed lines with 8 Ohms thru bypass. With a WeatherMax multi-layer grille, it can be installed both indoors and outdoors, and a InvisiBall mounting system allows for quick and easy installation.
