Natural Sound In A Natural Setting Sat 30The secret is deep bass. No outdoor speaker system can do it. Outdoors, with no walls or room corners to interfere, bass frequencies have nowhere to go, so they fly off into space leaving you feeling thin and tinny. Polk Audio's Atrium Sub10 changes that equation. It's a high-performance downward-firing subwoofer, constructed of waterproof materials and housed in a weather-sealed resin enclosure. The 10 long-throw Dynamic Balance driver turns the whole earth into your bass-producing instrument! This is deep, musical bass that will get you and your friends up and dancing. Meanwhile, the acoustically-matched Sat30 satellite speakers are free to rock out in the upper registers. You can use them with or without the Sub10. The detailed, high-fidelity sound of the Sat30 satellite speakers, when partnered with the Atrium Sub10 subwoofer, produces the kind of dynamic full-range performance that is guaranteed to get the party started, even in wide-open outdoor environments. More Than A Landscape SpeakerThe Sat30s are tastefully designed to mimic high-end outdoor lighting, so they can be installed anywhere, and they'll never get in the way of your landscape. They're color impregnated and impact tested, to stand up to the elements for years to come. The Sub10 is built tough. It can support up to 200 lbs, so you can use it as a plant stand or a side table. Its durable terracotta finish is paintable to match your outdoor decor. But the Atrium Sub10/Sat30 System is more than just a great outdoor speaker system. With multiple innovative mounting options for the Sat30s, you can enjoy the system anywhere, from your yard to your porch, in breezeways or pagodas, and in Florida rooms or sunrooms Anywhere you want to combine your love of the great audio with your love of the great outdoors rooms.
