Turn your backyard into an outdoor concert hall with Polk's Atrium4 speakers. These small speakers offer great sound, thanks to 3/4" tweeters and 4-1/2" woofers. And the rugged, weatherproof design meets or exceeds stringent military specifications for full exposure to the elements. That means you'll get years of superb performance, wherever you place them.

Polk's new Speed-Lock™ system makes mounting the Atrium4s quick and easy. Install the bracket and simply click the speaker into place. Just aim the sound towards your listening area and then tighten down the included thumbscrew.
