M O NITO R
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 chan-
nels 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 maxi-
mum 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 protec-
tive cover protects the drivers from dam-
age 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.
