Data Sheet

Technical
Specifications
The loudspeaker shall be a Bogen Orbit Model OCS1(B)
Ceiling Speaker or approved equivalent, consisting of one
6-1/2" (nominal) low frequency transducer, one 20mm
(3/4") (nominal) high frequency transducer with a filter
network for dividing frequencies between the transducers.
The front baffle shall be injection-molded, ABS material
containing fire inhibitors with a 94VO rating, and the back
can (enclosure) shall be steel. All components shall be
mounted inside the enclosure.
The baffle shall be supplied in off-white or black with a
mild texture finish to promote paint adhesion if desired.
A perforated speaker grille shall be made of steel, color-
matched to the baffle.
The low-frequency driver shall utilize a metal-alloy cone
with hard-anodized surface treatment for rigidity and
corrosion resistance. The cone shall provide a heat trans-
fer element for the voice coil under high-power input.
A compounded rubber cone surround shall be formulated
to withstand environmental conditions with high or low
heat, high or low humidity, and ultra-violet light. The voice
coil shall be protected via a high gauss low viscosity
magnetic liquid (ferrofluid), to prevent corrosion from
occurring in the magnet gap. The fluid will also serve as a
thermal path to further reduce heat build-up in the voice
coil. The driver will utilize the ferrofluid to provide a
centering force for the voice coil in the magnet gap.
The high-frequency driver shall utilize a diaphragm con-
sisting of black polycarbonate. Ferrofluid shall dampen the
voice coil and facilitate the transfer of heat from the coil to
the magnet structure.
Integral swing-out clamps shall provide a secure installation
in the ceiling surface. A safety cable attachment point shall
be included in the removable terminal cover enclosure.
An optional 10-foot long cable kit shall be available to serve
as a back-up support cable (Model CK10). An optional tile
bridge support ring installation bracket shall provide addi-
tional support when mounting the loudspeaker into sus-
pended ceilings (Model TBCR). The bracket shall also
serve as a pre-installation guide for new construction instal-
lations, providing attachment to either 16" OC or 24" OC
mounting.
The input connector shall be a 4-screw snap-lock input
connector, providing "loop-through" for additional speakers.
Power input selection shall be via a front-mounted rotary
switch, located under the removable grille. 70V (high-imped-
ance) tap selections shall be 1, 2, 4, 8, 16, and 32 watts;
100V (high-impedance) tap selections shall be 2, 4, 8, 16,
and 32 watts. A low-impedance 16-ohm selection shall also
be provided. Usable coverage area shall be 140°.
Dimensions of the speaker shall not exceed 12-3/8" dia.
x 12" D. Product weight shall be 10 lb.
