Polk Audio Atrium8 SDI

Details Use Polk's Atrium8 SDI speaker when you need maximum flexibility along with premium outdoor sound. It can stand alone as a single stereo speaker, or you can put two together for a high-performance stereo pair. One speaker is convenient when you want to pump tunes to a smaller area, like a deck or patio, or when mounting options are limited. If you have room for two speakers, these speakers will give you fuller sound and better stereo separation in larger listening areas.
