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.With the purchase of a second Bose SoundLink Revolve+ II, you can pair them both together in Stereo Mode or Party Mode. In Stereo Mode, you can playback music and other audio with proper left/right separation for more accurate sound reproduction. In Party Mode, both speakers will simultaneously play back the same audio, letting you place each speaker to properly accommodate very large or open-air areas.Multi-point technology lets you simultaneously pair this speaker with two different Bluetooth devices. Only one device can stream at a time, but multi-point makes it seamless to switch between the two.
