From Stereo to Surround Sound with no corruption or change to the original recording!

The Akoustos system will enhance your listening experience by producing the very best surround sound possible from the standard stereo signal that comes from your television, DVD/CD player, iPod, mobile device, gaming system or any other stereo device.
