Polk Audio Atrium 5 Outdoor Speakers with Powerful Bass (Pair, Black) – All-Weather Durability, Broad Sound Coverage…

Like all of our outdoor models, the Atrium 5 are All-Weather Certified and Water-Resistant—built to withstand the worst elements—salt-fog, UV, extreme temps or heavy rains, you name it. You’ll be enjoying great performance for years to come. It’s time to get that indoor sound you love—all from an outdoor loudspeaker you can put anywhere around your home. Aluminum grilles and bracket, with stainless steel and brass hardware means no rust—ever. Features Polk’s patented Dynamic Balance technology with 5″ Driver and 0.75″ Tweeter. Power Port Technology smoothly transitions air flow from the speaker into your listening area for deep, extended bass impact while minimizing turbulence and distortion. These speakers are easy to install and look great both outdoors and indoors.

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.)
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.”
