Superb sound for extreme locations. Sporting an ultra-durable, weather-proof construction, the Polk Atrium4 outdoor speaker pair effortlessly withstands the temperature and moisture extremes found in places such as the back deck, bathroom, or kitchen. And no matter where you place them, each speaker's combination of a 4.5" woofer and 0.75" tweeter serve up full, dynamic soundscapes, enhanced by Dynamic Balance and Klippel Optimization technologies. Finally, a Speed-Lock mounting system makes installation safe and hassle-free.

Rock out . . . rain or shine

Naturally, listening to music and relaxation are complementary activities. Hence the comfy couch and recliners in your home theater area. But let's be honest, the living room isn't the only place you like to relax: cool mornings on the front porch, lazy afternoons on the back deck, a bubble bath in the bathroom, and even cooking the kitchen. After all, few things can be as calming as the meditative process of preparing a meal. But extending your home audio into one of these areas can be a challenge — no, no, the wiring is no problem; it's the speakers you're worried about. After all, most loudspeakers are delicate instruments, and the moisture and temperature extremes found on the deck, in the bathroom, or in the kitchen can wreak havoc upon an ordinary speaker's performance. So, you need something other than "ordinary" speakers, something like the Atrium4 outdoor speaker pair from Polk. Combining a durable, mineral-filled polypropylene cabinet design with a sealed enclosure construction, aluminum grilles, and all stainless steel and brass hardware, this speaker pair not only earns All-Weather Certification, but also surpasses baseline industrial and military specifications for environmental endurance. Whether it's storming outside or you're cooking up a storm in the kitchen, the weather-proof Atrium4 speaker pair is ideal for extending your home listening experience into your favorite areas.

Superior technologies deliver superior performance

Chances are, if you've had any experience with outdoor speakers, you've been a little disappointed by their audio output. After all, while indoor loudspeakers have the luxury of working to fill small, enclosed areas, outdoor speakers face the challenge of creating full soundscapes in the limitless great outdoors. It's a tall order, but one that the Atrium4 speaker pair fills with authority. Each speaker's 4.5" long-throw, mineral-filled polypropylene cone driver combines with a 0.75" anodized-aluminum tweeter with neodymium magnet to serve up both surprising levels of bass response and smooth high-frequency output. Then, while Dynamic Balance technology zeros in on the optimal synthesis of materials, geometry, and construction techniques for pure, distortion-free sound, a state-of-the-art Klippel Distortion Analyzer optimizes woofer motor structure, voice-coil alignment, and suspension to bring you the best possible audio performance, even at extreme listening levels. The ultimate result is an exceptionally full and dynamic soundstage, even in outdoor listening environments.

It's a snap

You want to get to the part where you're reclining on the deck listening to your favorite album over your new Atrium4 outdoor speaker pair. But you're dreading one thing . . . the install. Well, we're here to tell you that your fears are for naught — Polk has designed the Atrium4 speaker pair with a Speed-Lock mounting system. All you have to do is mount the included bracket onto the wall and simply click the speaker into place. Then, just angle the speaker in the desired direction along its 180° plane of rotation, and tighten it down. Installation is effortless and safe.
