Data Sheet

Technical
Specifications
The loudspeakers shall be ORBIT Model OPS1W (Off-
white), and OPS1B (Dark Gray) or approved equivalent,
consisting of one 6-1/2" (nominal) low frequency trans-
ducer, and one 20mm (3/4") (nominal) high frequency
transducer with a filter network for dividing frequencies
between the transducers.
An injection-molded, ABS material containing fire inhib-
itors with a 94VO rating, shall house all components.
The enclosure shall be supplied in either off-white or
dark gray in color with a mild texture finish to promote
paint adhesion if desired. A perforated speaker grille
shall be made from heavy-gauge steel, color-matched to
the enclosure.
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
transfer element for the voice coil under high-power
input. A compounded rubber cone surround shall be for-
mulated 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.
The hanging cables shall be designed with forged eye
bolts captured on one end to attach directly to the enclo-
sure. The other end of the cables shall have a secured
loop that will attach to a quick connect clip. An integral
safety cable attachment point shall be included in the
enclosure. An optional 10-foot cable kit (CK10) shall be
available to serve as a back-up safety cable or main
suspension drop cable. An internal safety strap ensures
that the drivers are secured to the upper suspension.
The input connector shall be a 4-screw snap-lock
removable connector, providing "loop-through" for addi-
tional speakers.
Power input selection shall be via a front-mounted rotary
switch, located under the removable grille. 70V (high-
impedance) 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. Dispersion area shall
be 140°.
Dimensions of the speaker shall not exceed 15" diame-
ter x 9-1/4" high. Product weight shall not exceed 10 lb.
