Specifications
The loudspeaker shall be a NEAR Model A
1
2 with a
power handling capacity of 225W (
1
6-ohm) or
1
28W
(70V) or approved equivalent. The loudspeaker shall
consist of two 6.5" nominal low-frequency transducers
and one
1
.9" nominal mylar high-frequency transducer
with a filter network for dividing and smoothing fre-
quencies between the transducers. A mathematically-
aligned, vented enclosure shall house all components. All
vents shall be further protected from water ingress by
acoustically transparent fabric designed to shed water.
The enclosure shall be constructed from an injection-
molded, high-density (30% or greater) mineral-filled
polypropylene material compounded with UV
inhibitors.
Enclosure shall be molded in black. Surface shall be able
to accept paint. Perforated speaker grilles shall be made
from color-matched perforated polypropylene, also able
to accept paint if required.
The low-frequency drivers shall utilize a metal-alloy
cone with deep-anodized surface treatment for rigidity
and corrosion resistance. The cone shall provide a heat
transfer thermal path for the voice coil under high-
power inputs. Compounded rubber cone surrounds
shall be formulated to withstand all-environment instal-
lations, including salt spray, ultraviolet light (UV), chlo-
rine exposure, heat, cold, and constant humidity. The
voice coil will be centered via a high-gauss, low-viscosi-
ty magnetic fluid (Ferrofluid), which increases the heat
transfer rate from the voice coil under long-term high-
power use. The magnetic fluid shall prevent corrosion
from occurring in the magnet gap.
The high-frequency driver shall utilize an environmen-
tally stable Mylar diaphragm. An integrated horn and
phase compensation device shall provide increased out-
put sensitivity and controlled coverage of the output.
The mounting yoke provided with the speaker shall be
designed with a built-in angle to facilitate installation
when downward angulation is required, as well as
1
80-
degree left-to-right adjustment. The yoke shall be
formed from heavy-gauge stainless steel (minimum
3mm thick), and finished with a scratch-resistant paint.
In addition, an optional Adjustable Tilt-Mount Adapter
(Model TMA8
1
2) shall be available which provides addi-
tional angles for precise orientation vertically over
1
8
specified points.
The input connectors for
1
6-ohm and 70-volt systems
shall be gold-plated, rust-proof screws with integral
clamping washers.
Dimensions of the loudspeaker shall not exceed
1

1
/4" W x
1
7-7/8" H x
11
-3/4" D. Weight shall not
exceed 22 lb.
