Polk Audio Atrium 6 Speakers (Pair Black)

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 10098 for salt and corrosion
Anodized Aluminum Tweeter Domes with Rubber Surrounds are absolutely immune to the elements provide the smooth broad high-end range you need for larger outdoor spaces
Newly designed tweeter phase cap smoothes the frequency response from 12KHz up to 20kHz the last audible octave
Broad Coverage Baffle Design adapted and applied from our current Atrium design but a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area
Speed-Lock Mounting System for easy safe one-handed installations even in difficult locations The greatly simplified mounting procedure means fewer parts to juggle
