Atrium 6

Extraordinary bass response

PowerPort® Bass Venting

You’ll experience space-filling sound in any outdoor area, porch, sunroom, or deck. Polk’s patented water-resistant PowerPort® efficiently adds 3dB of big, realistic, musical bass output. And when combined with its anodized aluminum tweeter domes, this speaker not only delivers powerful, high-quality sound output, but excellent midrange clarity.

Great outdoor sound

Patented Dynamic Balance®

Whether you’re lounging in your favorite chair, hosting a BBQ, or spending time with the family outdoors, you won’t miss a single word of your favorite tunes. The Atrium Series outdoor speakers deliver crisp, powerful vocals—without distortion. Their Patented Dynamic Balance® and Klippel Optimization Technologies ensure optimal material performance, eliminating driver and tweeter “artifacts” for more realistic sound reproduction at high and low volume levels.

Polk All-Weather Certified

Made to withstand the elements, these speakers are built to last and produce rich, lifelike, space-filling sound—no matter the weather. 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).

Speed-Lock™ Mounting System

Sprucing up the patio or backyard is a cinch with easy, secure one-handed installations even in difficult locations. The Speed-Lock Mounting System ensures easy, safe one-handed installations and no-slip setting of the speaker angle. This greatly simplified mounting procedure means fewer parts and a quicker setup.
