The Harman/Kardon Aura Studio 3 is a 360-degree wireless Bluetooth speaker that has a total of six mid-treble drivers spread around the perimeter of the speaker. For the bass range, the company packed a 130mm woofer drive, that is capable of 100W of power to handle the bass, even without the bass port. This effectively turns the Studio 3 into a closed cabinet sound system. (06M Warranty) mobile and Original accessories needs
