The Atrium 55 Indoor/Outdoor
Loudspeaker is the ultimate in flexibility, reliability and high fidelity sound quality for the great outdoors. The Atrium 55 gives you the freedom to put speakers anywhere you want high performance sound. The kitchen, the den, the guestroom, the patio or pool, even the backyard BBQ pit.
Sure, there are lots of "outdoor" speakers out there. But look at the fine print. Many of them are suitable only for placement in sheltered locations. The rugged Atrium 55 meets or exceeds stringent industry and military specifications for full exposure to the elements for years of reliable high performance sound anywhere in and around your home.

Incredible sound... anywhere you want it, with the versatile Polk Audio Atrium Series of Indoor/Outdoor Loudspeakers.
