Devialet Mania Portable Bluetooth Speaker

This speaker has four full-range drivers set in the top half of the dome-shaped casing. These are alternately left- and right-channel aluminum drivers, so however you're oriented to the Mania, you'll hear true stereo sound. The side-firing bass woofers move in sync to cancel out unwanted vibrations. This lets the deepest bass frequencies come through. Full 360° sound-field.
