The A2is compact and designed for smaller
spaces or applications. Its high audio intelligibility and
superb articulation make it the ideal loudspeaker for
music or paging, inside or out.
The A8is the largest and highest
output model, and designed to perform in
settings from clubs and auditoriums to stages
and theme parks.
The A6is a conveniently sized
2-way, high-power speaker. It delivers superb
results in restaurants, health clubs, patios/decks
and waterside areas.
Designed to Perform Anywhere
The A-Series offers a range of choices to suit every application where sound quality is crucial.
Actual speakers colors may not match those shown here.
Colors specified by adding suffix to model number: BLK (black), GRN (green), or WHT (white).

Advanced Rubber Compound
With advanced rubber cone surrounds, premium
driver materials, a fully sealed cabinet, and
corrosion-resistant hardware, you have a series of
speakers engineered for consistent quality and
performance...both indoors and out.
Metal Diaphragm Technology
Special MDT™ (Metal Diaphragm Technology)
metal-alloy speaker cones are light, yet rigid,
which allows them to produce natural sound with
ultra-low distortion.
Here is a summary of MDT™ benefits:
•High rigidity and low mass of metal cone
versus traditional papers and plastics
•Special anodizing process creates a ceramic
coating for increased stiffness
•Large metal cone area assists in cooling voice
coil under long-term, high-power situations
•Extremely durable cone structure over long
periods of time
Magnetic Liquid Suspension™
Unique and patented MLS™ (Magnetic Liquid
Suspension) technology uses a magnetic ferrofluid
and the speaker’s own magnetic field to precisely
center the voice coil in the magnet gap and eliminates
the distortion-causing voice coil spider found in
conventional speakers. In fact, the louder it plays,
the more accurate the centering force becomes.
Here is a summary of MLS™ benefits:
•Voice coil is constantly centered as it moves up
and down, for lower distortion
•Magnetic fluid transfers heat away from the voice coil
to the basket and magnet, keeping the moving parts
cool at high operating levels
•Greater linearity is accomplished because the
mechanical spider is eliminated for more precise sound
•Constant ferrofluid lubrication of the gap seals the
opening and prevents oxidation in the toughest
environments and conditions
•Longer excursions with smaller diameter woofers
provides speaker with even greater bass response
(spiders limit excursions in traditional speakers)
•Distortion is further reduced at high output
levels through use of a dual-layer voice coil
with separate inner and outer windings
The Ultimate Pairing of
Performance and Durability
NEAR

A-Series
Loudspeakers
Tough, Innovative Design
The NEAR A-Series is made of premium material components: die-cast aluminum frames,
hard anodized aluminum cones, black anodized aluminum voice coil formers, proprietary rubber
compound for speaker surround, high-temperature adhesives, UV-inhibited mineral-filled
polypropylene
enclosure, powder coated aluminum, perforated PVC plastic grilles,
threaded brass
inserts, and gold-plated connectors. These are the most
durable materials used in any speaker in the industry!
Mounting Brackets
Installing A-Series speakers is quick and easy with the A-Series’
unique mounting brackets. The speakers are designed to slide
into the slots in the brackets, with knobs attached. Plus, the knobs
are oversized for easier grip and better control during installation
while standing on a ladder.
Connections
Gold-plated connectors ensure high-quality sound and durability.
Rust-resistant hardware protects A-Series speakers from the rigors
of nature...making them an ideal choice for almost any environment.
ASTB4: A-Series Speaker Terminal Boot*
The A-Series Terminal Boot is designed to shed
water and to offer added protection against the
effects of weather on wires and connections made
to the speakers.
Form Follows Function
Heavy wall, mineral filled with polypropylene, cabinet
is impervious to the effects of weather and sonically
dead. The A-Series’ unique “Armadillo ribs” provide
rigidity to the straight wall sections while hemispherical
ends are naturaly rigid. Together they provide a stiff
but acoustically damped cabinet.
Cast Aluminum Basket
The cast aluminum basket is rigid and lightweight.
Sealed Magnet
A proprietary Ferrofluid used in the speaker effectively seals
the magnet gap and voice coil against moisture and corrosion,
assuring long life under difficult environmental conditions.

A-Series Loudspeakers
* Accessory; sold separately
NEAR A-Series speakers set the standard for smooth, accurate sound,
attractive appearance and rugged construction. Designed to perform
beautifully under the toughest conditions, the A-Series combines outstanding
industrial design with NEAR-patented speaker technology
for unsurpassed audio quality and weatherproof durability.
Sound Design, Through and Through
Form follows function in the A-Series. Its rounded ends and
unique side corrugations give the speakers their character-
istic “armadillo” look and are designed to reduce cabinet
resonance and improve sound quality.
The heavy, molded speaker cabinets are made from
a unique, UV-inhibited mineral-filled polypropylene, making
them extremely durable and giving them excellent acoustic
properties. All mounting hardware is rust-proof ... from the ergonomic,
over-sized mounting knobs to the heavy-gauge aluminum or stainless steel
brackets, which are powder-coated to resist chipping and scratching.
So, whether you need an A-Series speaker for a frosty ski slope
or baking in the sun and salt spray seaside, you can count
on it to look good and sound great.
