The Puck is a Fusion-designed mounting solution that allows you to securely attach a Stereoactive and/or Activesafe to the surface of a paddle board, kayak, canoe, dinghy/tinny/jon boat and even a jacuzzi - leaving you to enjoy your music rather than worrying about your stereo floating away in the water. You can be confident that you can truly Puck your Stereoactive and/or Activesafe anywhere.
