For all their engineering, speakers are mostly just formless boxes—eyesores that we shove into corners and forget about. The Harmon Kardon Aura is one that even the most design-conscious can proudly plop in the middle of their living rooms. Engineers molded the six-driver Bluetooth speaker into a retro-futuristic dome that evenly distributes audio 360 degrees. A 30-watt subwoofer fires up into the dome, which radiates the bassline up, out, and into the room—instead of into the floor. Interior LEDs sync with the music to draw a little extra attention.
