Patented Dynamic Balance®

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.

"These Polk outdoor speakers are awesome. Look great and sound great."

"Sound quality and performance of both speaker systems far exceed all expectations and reviews I have read. Superior products, attention to detail and quality not readily found in todays' market."

– Ric P., Verified Buyer

"I bought these speakers 13yrs ago and installed them in the cockpit under the rear rail seats of the sailboat. Talk about an ugly environment. They sound great. Never a problem. Love them."

– Bill1, Verified Buyer

"I bought two pairs for my patio and pool area. These speakers are fantastic!"

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.

Paintable Finishes

Available in durable, weatherproof black or white paintable finishes, Atrium speakers are easy to integrate into any décor. And with Aluminum Grilles and Bracket, stainless steel and brass hardware, these speakers will remain rust-free for years to come.
