About the Polk Atrium 55

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 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 90º 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.

The white Atrium 55 can be painted to match the color its surroundings.

Features

Weatherproof: The rugged, mineral-filled polypropylene enclosures not only feature rust-proof hardware and grilles, but also meet or exceed stringent military specifications for full exposure to the elements. Unlike many other "outdoor" speakers that require sheltered locations, the Atrium55 speakers can be mounted anywhere, even out in the open.

Woofers: Each speaker uses a mineral-filled polypropylene Dynamic Balance woofer for clean midrange and deep, accurate bass. For a smoother response and improved durability, each woofer uses a butyl rubber surround.

Tweeters: Each speaker has a 1" metallized Polymer composite dome tweeter. The tweeters broadly distribute high frequencies to cover a large area with high-fidelity sound.

Mounting Brackets: The included mounting brackets add complete placement flexibility. They allow you to rotate the speakers by 90 degrees after they've been mounted, letting you direct the sound to different areas as needed. If the speakers are mounted vertically, the brackets allow them to swivel side to side. If the speakers are mounted horizontally, the brackets allow them to swivel up and down.

5-Way Binding Posts: The gold-plated 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.
