Polk Atrium 6 - 5.25 in Indoor Outdoor Speakers
First introduced in 2002, the outdoor Atrium Series set a new standard not only for build quality, but sonic performance, too. But we couldn’t leave well enough alone. Not only does our new, refined Atrium Series offer better sonic performance and easier install/mounting options, the series also exceeds the standard military specification weather tests, setting a new standard for rugged outdoor durability under our own more rigorous weatherproofing certification program. The results are a pure joy to listen to. So that wherever you put your Atrium speakers—by a pool, on a deck or in a sunroom, you can be confident they’ll deliver great sound year round.
• Atrium Series Speakers exceed baseline industrial and military specifications for environmental endurance.
• (ASTM D5894-UV Salt Fog, Mil Standard 81 Immersion, Mil-Std 883 Method 19.8 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 2kHz, the last audible octave.
