Polk’s Atrium 65SDi speaker offers great outdoor sound and exceptional flexibility. It can stand alone as a single stereo speaker, or you can put two together for a high-performance stereo pair. Using one speaker is convenient for listening in a smaller area (like a small deck or patio) or where mounting options are limited. Or use two speakers for fuller sound and better stereo separation in larger listening areas. A simple switch on the back makes it easy to choose between single-speaker or traditional two-speaker stereo. Either way, you’ll enjoy clean, rich Polk sound with impressive dynamics.
As always, Polk has taken great care in the design of this versatile speaker. A 6-1/2″ long-throw driver with dual voice coils delivers robust bass response, and two 1″ dome tweeters dish out crisp, accurate highs. (When using the Atrium65SDi as a single stereo speaker, the dual tweeters and dual voice coils handle the left and right signals independently.) A Power Port vent reinforces the low-frequency output, and the rounded enclosure minimizes diffraction for more open and lifelike imaging.
This tough speaker is built to stand up against harsh weather conditions. The hardware is made of stainless steel for many years of rustproof reliability. The Power Port features a flared “umbrella” diffuser design that meets basic military waterproofing specs (and it acts as a bug screen!). And for outdoor locations that receive direct moisture, use the included Port Plug ? it enabled the Atrium 65SDi to pass the rigorous Salt Fog test, proving that this hard-nosed speaker can hold its own against the elements. You even get a rotating rustproof aluminum bracket for easy outdoor wall-mounting.
