Spec Sheet

Technical
Specifications
The loudspeakers shall be NEAR ORBIT Model OPS1W
(White), and OPS1B (Black) or approved equivalent, con-
sisting of one 6-
1
/2" (nominal) low frequency transducer, and
one 20mm (
3
/
4") (nominal) high frequency transducer with a
filter network for dividing frequencies between the trans-
ducers.
An injection-molded,ABS material containing fire inhibitors
with a 94VO rating, shall house all components.
The enclosure shall be supplied in either white or black 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 cor-
rosion resistance.The cone shall provide a heat transfer ele-
ment for the voice coil under high-power input. A com-
pounded rubber cone surround shall be formulated to with-
stand 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 (fer-
rofluid), 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 consist-
ing 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 enclosure.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 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 pro-
vided.
Dimensions of the speaker shall not exceed 15" diameter x
9-

4" high.Weight shall not exceed 10 lb.
