A-Series All-Environment Loudspeaker The Leader in Metal-Alloy Speaker Technology Models A8, A8T, A8E Features Indoor and outdoor all-weather speaker with fully-sealed cabinet Available versions: 8-ohm, 7V, 1V Available colors: black, green, white NEAR-patented metal-alloy MDT mid/bass speaker cone delivers natural sound with ultra-low distortion Extremely stable, long-lasting MDT cone structure High-efficiency and power handling for optimum performance Dual-layer voice-coil with separate inner and outer windings for high output with ultra-low distortion NEAR-patented MLS fluid voice-coil suspension replaces distortion-causing mechanical spider Compound rubber surrounds resist UV rays and salt spray Gold-plated stainless steel connectors High-density, injection-molded cabinet resists chipping and scratching Low-resonance cabinet structure Easy-to-grasp multi-faceted mounting brackets with 18 o swivel Easy grip oversize mounting knobs Brackets mount with knobs attached for easier and safer installation in hard-to-reach locations Heavy-gauge aluminum (A2 & A6 models) or stainless steel (A8 models) brackets Corrosion-resistant frame and mounting hardware Attractive styling with Armadillo ridges for stiffness Coaxial (A2 models) or 2-way speaker systems (A6 & A8 models) Description NEAR A-Series Armadillo loudspeakers feature NEARpatented technologies that improve sound quality and operating reliability. Attractively styled, they are engineered for both indoor and outdoor applications.the A8 models are high-output, 2-way designs for larger spaces such as clubs, auditoriums, and theme parks. The compact A2 models are designed for smaller spaces. Their high audio intelligibility and superb articulation make them ideal for music or paging applications.the A6 models are conveniently-sized, 2-way designs with high-power handling for applications such as restaurants, health clubs, and patio and pool areas. All models feature NEAR s MDT (Metal Diaphragm Technology) and MLS (Magnetic Liquid Suspension). Exclusive MDT (Metal Diaphragm Technology): High rigidity and low mass of metal versus traditional papers and plastics Extremely stable cone structure over long periods of time Fast transmission of sound through the diaphragm means low energy storage Special anodizing process creates a ceramic coating for increased stiffness Efficient heat-sinking of voice-coils under long-term, high-power situations Unique MLS (Magnetic Liquid Suspension): Voice-coil is constantly centered for lower distortion Voice-coil is more efficiently heat-sinked by fluid instead of air Greater linearity is accomplished because the mechanical spider is eliminated Constant lubrication of the gap prevents oxidation from outdoor use Additional information at www.nearspeakers.com Specifications subject to change without notice. 2 Bogen Communications, Inc.

A weather-tight enclosure shall house all components. The enclosure shall be constructed from an injection-molded, high density (3% or greater) mineral-filled polypropylene material compounded with UV inhibitors. Three molded-in colors shall be made available (Black,White, Green). Perforated speaker grilles shall be made from heavygauge PVC, color-matched to the enclosure.an integral safety strap mounting point shall be included. 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 environmentally stable 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-81E 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. The loudspeaker shall rotate about its axis a minimum of 18 o.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 7-volt, and 1-volt systems shall be gold-plated, stainless-steel screws with integral clamping washers. Dimensions of the system shall not exceed 17-13/16 Long x 1-3/16 Wide x 1-7/8 Deep. Weight shall not exceed 18 lbs. (A8), and 2 lbs. (A8T & A8E).The system shall be the NEAR Model A8 (8-ohm) or Model A8T (7V) or Model A8E (1V) in Black (BLK),White (WHT) or Green (GRN).
