The sound is simply excellent, the powerful is really surprising given the size of the enclosure. In one room, it is hardly if one hears when thoroughly. Hold tight the load 15h announced, for my part I will leave instead of 10 to 12 (depending on the Volume). An app is also disponilbe for iOS and Android that allows to couple two stereo speakers (one for the right and for the left or 2 in stereo). Possibility to suspend or place it on a tripod thanks to its screw. In short, if you please, please!
