Description

The CIS300 is a compact two-way flush-mount loudspeaker assembly designed for fixed installations into typical ceiling plenum spaces. Employing a modified HF waveguide originally developed for use in studio monitors, the CIS300 delivers superior dispersion and pattern control over conventional coaxial designs. The waveguide integrates the HF driver with a 4 LF driver optimized for smooth frequency response and seamless transition through the crossover point. The result is acoustic performance not generally associated with a commercial ceiling speaker of this size or in this price range.

The CIS300 is supplied fully assembled, complete with a sealed zinc-coated steel backcan and cam-style installation clamps. The metal enclosure includes a recessed Euroblock input connector with detachable mating plug, concealed behind a hinged metal cover plate. A welded tab is provided for seismic restraint. Two steel T-Bar support channels are provided to facilitate installation to a standard tile ceiling. Also supplied is a steel split C-ring, which serves to disperse the clamping pressure of the mounting cams.

The CIS300 is supplied with an integral 70/100V line transformer rated to a maximum of 30 watts. Power is adjustable by means of a recessed rotary switch on the front bezel, and allows selection of 30, 15, 7.5, and 3.7 watt taps. A second recessed rotary switch is provided to engage a 16-ohm tap for use with low-impedance amplifiers, or a 150 Hz high-pass filter.

The speaker assembly is shipped with a detachable paper cover fitted over the transducers inside the bezel. This protective cover protects the drivers from damage during installation and also serves as a paint cover, allowing convenient spray painting to match interior d?cor. A powder-coated perforated steel grille is supplied, and easily installed once the desired Tap Selector and Full-Range/High-Pass switches have been set.

The entire assembly is fully tested at the time of manufacture and is warranted to be free from defects in materials and workmanship for a period of five years from the date of purchase. The speaker is designed for use in ceiling plenum spaces and meets UL 1480 and UL 2043 regulations governing signaling devices and plenum applications.
