Technical
Specifications
The loudspeaker shall be a NEAR Model A8 (8-ohm) or
Model A8T (70V) with a power handling capacity of 175W
(8-ohm) or 64W (70V) or approved equivalent. The loud-
speaker shall consist of one 8-inch nominal low frequency
transducer and one 1-inch nominal titanium high frequency
transducer with a filter network for dividing frequencies
between the transducers. A weather-tight enclosure shall
house all components. The enclosure shall be constructed
from an injection-molded, high density (30% or greater) min-
eral-filled polypropylene material compounded with UV
inhibitors.
Three molded-in colors shall be made available (Black,White,
and Green). Perforated speaker grilles shall be made from
heavy-gauge PVC, color-matched to the enclosure.
The low frequency driver shall utilize a metal-alloy cone with
deep-anodized surface treatment for rigidity and corrosion
resistance.The cone shall provide a heat transfer element for
the voice coil under high-power input. Compounded rubber
cone surrounds shall be formulated to withstand all-environ-
ment installations, including salt spray, ultraviolet light (UV),
heat, cold, and constant humidity.The voice coil will be cen-
tered via a high gauss, low viscosity magnetic fluid (ferroflu-
id), 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 environmentally sta-
ble titanium diaphragm. Ferrofluid shall dampen the voice coil
and assist in the heat transfer for higher power capability.
Environmental testing shall ensure long-term operation in all
weather. Specifications shall exceed Mil-Std-810E Test
Methods for Temperature, Humidity, Ultra-Violet Light, and
Salt Spray.
The mounting bracket shall be designed with multiple angles
to facilitate installation in corners or when angulation is
required. An integral safety strap mounting point shall be
included. The loudspeaker shall rotate about its axis a mini-
mum of 180o.The bracket shall be formed from heavy-gauge
stainless-steel (minimum 3mm thick), and finished with a
scratch-resistant paint (color-matched to the enclosure).
The input connectors for 8-ohm and 70-volt systems shall be
gold-plated screws with integral clamping washers.
Dimensions of each speaker shall not exceed 10-1/4" W x
17-7/8" H x 10-7/8" D. Weight shall not exceed 18 lb. (A8),
and 20 lb. (A8T).The system shall be the NEAR Model A8 (8-
ohm) or Model A8T (70V) in Black (BLK),White (WHT) or
Green (GRN).
