Product Inquiry

No matter how you like to play outdoors, there’s an Atrium Loudspeaker that loves to play and play and play and play and play.
 In fact, our engineering and industrial design teams spent months looking at any and every detail that could make these new Atriums perform better, mount faster and be even more reliable. When you set out to improve a loudspeaker with the pedigree of the Atrium Series.

The Polk Audio Atrium 8SDI is a great outdoor speaker that can be used for both small and larger outdoor areas. This unit was initially designed to suit the needs of clients that didn't have the space for 2 outdoor speakers so it was designed as a "Single Point Stereo" unit (i.e. both Left and Right audi channels are wired to this one speaker.

If you have a larger outdoor area, the Polk Audio Atrium 8SDI can be wired as a conventional Left or Right speaker. This is one very versatile speaker solution that can please just about anyone.

The Polk Audio 8SDI is a Single Point Stereo Speaker and is sold as individual units. For larger outdoor areas you can order 2 of these and use them as a typical Left or Right Outdoor Speaker.
