Polk Atrium4 Specifications Sheet

All-weather outdoor loudspeaker

Atrium4

The compact Atrium4 loudspeaker produces high fidelity sound
quality anywhere you want great sound. It’s small size makes it
ideal for tight, out-of-way installations. By the pool, around the
kitchen, tucked away in the family den or filling the backyard with
great sound. Like our bigger Atriums, the Atrium4 is built rugged to
deliver years of great performance fall, winter, spring and summer.

4 1/2-inch (11.43cm) long-throw mineral-filled polypropylene
cone driver with butyl rubber surround pumps out surprising bass
response from a compact design.

3/4-inch (19mm) anodized aluminum dome tweeter with neodymium
magnet for better power handling and smoother response.

Product Preview

Broad coverage baffle design, adapted and applied from our current
Atrium design but with subtle improvements in the new Atrium
Series.

Polk 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 worst Mother
Nature can dish out, whether its extreme temps or heavy rains.

Speed-Lock™ mounting system, for easy, safe one-handed
installations even in difficult locations.

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 truly great sound, no matter
what the weather.

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.

All Polk products are made using the best materials and the most
advanced manufacturing techniques. They pass the industry’s most
exhaustive quality tests, including drop testing, extreme signal
response and UV & salt exposure testing. Polk loudspeakers are
built to perform for a lifetime.
