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 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 décor. 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.
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 lowimpedance amplifiers, or a 150 Hz high-pass filter.
