Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Outdoor Speaker
Weatherproof Design: Polk Audio All-Weather Certified,
Atrium Series speakers exceed baseline industrial and military specifications
for environmental endurance (ASTM D5894-UV Salt Fog, Mil Standard 810 Immersion,
Mil-Std 883 Method 1009.8 for salt and corrosion.) Certification means Atrium
speakers can effortlessly withstand the outdoors, and hold up in extreme
temperatures and precipitation.
Driver Technology
Polk Patented Technologies: Patented Dynamic Balance and
Klippel Optimization technologies ensure the perfect material performance,
eliminating driver and tweeter "artifacts" for more realistic sound reproduction
at high and low volume levels.
- Dynamic Balance: A Polk perfected method of analyzing a
speaker's microscopic behavior with laser Interferometry. Polk engineers can
tune out unwanted resonance and distortion with the right combination of
materials, geometry and construction techniques. This brings you pure,
distortion-free sound.
- Klippel Optimization: By using a state-of-the-art
Klippel Distortion Analyzer, Polk engineers were able to optimize the
woofer's motor structure, voice coil alignment and suspension bringing you
the best possible performance even at extreme listening levels.
Woofer: Each speaker features a 5 1/4" (13.34cm) long-throw
aerated polypropylene cone driver for clean midrange and deep, accurate bass.
For a smoother response and improved durability, each woofer uses a butyl rubber
surround.
Tweeter: Each speaker features a 1" (25.4mm) anodized
aluminum dome tweeter with rubber surround and neodymium magnet for better power
handling and smoother response.
Enclosure Design
Rugged Enclosure Design: The durable, mineral-filled
polypropylene cabinet design, with molded-in bracing, sounds like a real speaker
(not "an outdoor speaker"), and survives years of seasonal changes, for great
sound, no matter what the weather. The rugged, mineral-filled polypropylene
enclosure features a rustproof aluminum grille, rustproof aluminum bracket, and
stainless steel/brass hardware.
Note: The speakers are available in a black or white
finish. The enclosure is also paintable.
Broad Coverage Baffle Design: The sculpted front,
steeply-angled baffle design and rounded enclosure minimize diffraction (sound
reflecting off of hard edges) for more open and lifelike imaging.
Connections
5-Way Binding Posts: The Atrium 6 has a pair of gold-plated
5-way binding posts that will accept bare wire, pin connectors, spade
connectors, and banana plugs (single or dual).
Mounting Options
Speed-Locking Mounting System: The included rustproof
aluminum brackets allow multiple mounting options and are quick-and-easy to
install. The Atrium 6 can be mounted either horizontally or vertically and aimed
to deliver the best possible sound in a variety of situations The integrated
brackets provide full 180-degree rotation (when mounted vertically or
horizontally. The mounting brackets even allow the speaker to be mounted snugly
in a corner or under an eve (at a downward 45-degree angle). You can remove the
bracket and use the speaker's built-in stability feet, if you simply want to
place the speaker on a table or shelf.
