Polk Atrium 45 Indoor/outdoor speakers

Put great Polk performance to work wherever you want it. The Atrium 45 offers great sound, thanks to its 3/4" dome tweeter and 4-1/2" Dynamic Balance woofer. And the rugged, weatherproof design meets or exceeds stringent military specifications for full exposure to the elements. That means you'll get years of great sound from these speakers, wherever you put them.

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 45s are also voice-matched to Polk's RTi speakers, and therefore make great surrounds in a complete Polk home theater system.
