The Atrium 55 combines superb Polk sound with an extremely durable design for an outdoor speaker that will deliver years of outstanding performance. The rugged enclosures not only feature rust-proof hardware and grilles, but also meet or exceed stringent military specifications for full exposure to the elements. And you’ll love the clean, dynamic sound of its 1″ dome tweeter and 5-1/4″ Dynamic Balance woofer.
The included mounting brackets add complete placement flexibility. They also allow you to rotate the speakers by 90? after they’ve been mounted, letting you direct the sound to different areas as needed. The Atrium 55s are also voice-matched to Polk’s RTi speakers, and therefore make great surrounds in a complete Polk home theater system.
