Over 80 aerodynamic, acoustic and mechanic specialists worked with Devialet for more than a decade to develop this 'Classic Phantom' speaker, which, according to the French brand, delivers the best sound quality in the world. Designed in a spherical shape proven by physicists as the best way to transmit sound waves evenly in all directions, it has ADH® to cancel out background noise, HBI® ('Heart Bass Implosion') to create the lowest frequencies ever emitted and SAM® ('Speaker Active Matching') to reproduce the exact pressure level as when the music was recorded. Connect via Bluetooth, WiFi, or AirPlay® to wirelessly transmit all of your tunes through a single user-friendly application.
