Technical

Specifications

The loudspeaker shall be a Bogen Model A2 (8-ohm)

or Model A2T (70V) with a power handling capacity of

100W (8-ohm) or 16W (70V), or approved equivalent,

loudspeaker consisting of one 6-inch nominal low

frequency transducer, one 1/2-inch nominal high

frequency transducer mounted coaxially, 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), mineral-filled

polypropylene material compounded with UV inhibitors.

Two molded-in colors shall be made available (Black

and White). Perforated speaker grilles shall be made

from heavy-gauge PVC, color-matched to the enclo-

sure.

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-environment

installations, including salt spray, ultraviolet light (UV),

heat, cold, and constant humidity. The voice coil will be

centered via a high gauss, low viscosity 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 polycarbonate 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 any weather. Specifications shall meet or exceed

Mil-Std-810E Test Methods for Temperature, Humidity,

Ultraviolet Light, and Salt Spray.

The mounting bracket shall be designed with multiple

angles to facilitate installation in corners or when angu-

lation is required. An integral safety strap mounting

point shall be included. The loudspeaker shall rotate,

on its axis, a minimum of 180o. The bracket shall be

formed from heavy-gauge aluminum (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

9" Wide x 8" Diameter x 8-1/4" Deep (with knob &

bracket). Product weight shall not exceed 8 lb. (A2), or

10 lb. (A2T).
