• Owners Manual

Like all our other multi-application loudspeakers that were created to live and play outdoors, the Atrium45 meets or exceeds several stringent military waterproofing specifications. The loudspeaker's unobtrusive, compact design makes it easy to tuck under eaves, but there's nothing small about its sound.

Key Features:

• Premium Outdoor Construction
  Atrium Series speakers are for all seasons: winter, spring, summer and fall. A super dense glass-filled ABS cabinet made of a space age polymer has internally molded-in bracing for all Atrium models, which eliminates the typical "plastic trashcan sound" found in other outdoor speakers.
• 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.
• Dynamic Balance and Klippel Optimization
  Like all high quality Polk speakers, the dome tweeters and polymer drivers in all Atrium series speakers are both Dynamic Balance and Klippel Optimized. Dynamic Balance allows us to see the operation of the component on a microscopic level, reducing or eliminating artifacts that color the sound. Klippel Optimization ensures the speaker will perform well at both low and high volumes levels. For more information, click here for Dynamic Balance and here for Klippel Optimization.

• Blue Polymer Woofers with Rubber Surround
  Provide excellent damping and bass response while resisting deterioration. Your Atrium Speakers may last longer than the house they're installed in. Other speakers use flimsy paper cones and foam surrounds that can fall apart.
