Not only are we a dealer of Sonos, but we have been awarded Sonos' Gold Certification due to our close partnership and deep knowledge of Sonos products. Sonos merges all of your music sources and lets you control them from the convenience of your smartphone, tablet, or computer. Your iTunes library, the music living on your phone or tablet, Pandora, Spotify, services like Sirius/XM.

This can be added to an existing stereo system or home automation system, or Sonos also has speakers that allow you to add music to any room in your home, wirelessly. No more running that long cord from your computer over to the stereo. All the music on earth. In every room. Wirelessly.
