CIS991
High-Output Ceiling-Mounted Loudspeaker DESCRIPTION The CIS991 ceiling loudspeaker features a powerful 3-way design that provides exceptional performance, especially in high ceiling, large-space applications. The CIS991 (80-degree by 80-degree dispersion) incorporates four 5.25-inch LF cone woofers, four 4-inch MF cone woofers and a 1-inch-exit HF compression driver mounted on a large horn that foster superior pattern control. The application of proprietary frequency shading techniques facilitates the eight cone woofers working together to provide LF output and impact equal to that of a 12-inch LF woofer. The CIS991 is supplied with an integral 70V/100V line transformer, rated to a maximum of 128 watts. Tap settings are adjustable by means of a recessed rotary switch on the front bezel that allows selection of 128-, 64-, 32-, and 16-watt taps at 70 volts, and 128-, 64-, and 32-watt taps at 100 volts. In addition, the transformer can be bypassed, presenting an 8-ohm load to low-impedance systems. A sealed, painted, 18-gauge steel back can is square in shape, and designed to mount in a 24-inch ceiling grid. The back can includes a recessed Euroblock input connector, with detachable mating plug, concealed behind a hinged metal cover plate. A ceramic screw terminal block is also present. Mounting is accomplished using the integral eyebolts on the rear to suspend the loudspeaker with optional, adjustable, wire rope rigging. A cable clamp secures the incoming loudspeaker cable. 22.60 in 574.1 mm
