Providing portable audio that can fill a room, the Bose SoundLink Revolve+ II Bluetooth Speaker sports a downward-firing full-range transducer and omnidirectional acoustic deflector. This means that the SoundLink Revolve+ II can deliver 360° of audio throughout a room, whether it's placed dead center or against a wall, reflecting audio to you and your guests. The addition of dual passive radiators supports deep bass and reduces vibration. On a full charge, you get up to 17 hours of audio that's loud enough for large gatherings. An integrated flexible, fabric handle makes it easy move the Revolve+ II anywhere.
