MIL-SPEC WATER PROOFING
Polk Audio Atrium Series Loudspeakers meet or exceed industry and military specifications for environmental
endurance. The tests have coded names like “ASTM D5894-UV Salt Fog,” “Mil standard 810 Immersion” and
“Mil standard 883 Method 10098 for salt and corrosion.” Passing them means that Polk Multi-Application
Loudspeakers can withstand some of the worst that Mother Nature (or your bathroom or kitchen installation
location) can dish out. See more about Mil-Spec Waterproofing at www.polkaudio.com/catalog/technology/.

DYNAMIC BALANCE®
Advanced laser imaging technology allowed Polk Audio engineers to see the entire vibrating surface of a driver
and tweeter; they could actually see the resonance develop on the speaker cones—resonance that is the root
cause of loudspeaker distortion (A). Being able to see the resonance develop, they determined the “Dynamic
Balance” of high-tech materials, geometry and construction that effectively tune out the offending resonance
(B). Exclusive Dynamic Balance Composite Material Technology delivers sound that’s effortlessly clean and
clear, even at lifelike volume. See more about Dynamic Balance at www.polkaudio.com/catalog/technology/.
