Polk Audio Atrium 8 SDI Speaker (Single, Black)

Dynamic Balance Technology This patented technology analyzes the speaker?s entire electro-acoustic and mechanical system for improved material selection and more efficient geometry. All-Weather Certified and Water-Resistant Built to withstand the worst elements?salt-fog, UV, extreme temps or heavy rains, you name it. Durable Construction Aluminum grilles and bracket, with stainless steel and brass hardware means no rust?ever. First introduced in 2002, the outdoor Atrium Series set a new standard not only for build quality, but sonic performance, too. But we couldn’t leave well enough alone. Not only does our new, refined Atrium Series offer better sonic performance and easier install/mounting options, the series also exceeds the standard military specification weather tests, setting a new standard for rugged outdoor durability under our own more rigorous weatherproofing certification program. The results are a pure joy to listen to. So that wherever you put your Atrium speakers—by a pool, on a deck or in a sunroom, you can be confident they’ll deliver great sound year round.
