With its debut soundbar, Devialet delivers authentic, high-fidelity home theatre audio from a stylish enclosure that hides a slate of innovations. Chief among these are the brand’s proprietary ADH amplification and speaker active matching (SAM) processing, which provide both tangible power and exemplary control over the Dione’s eight independent bass units. Joining the fun are side-firing and upfiring full-range drivers for Dolby Atmos/surround playback, plus the distinctive Orb centre channel, which can be rotated to ensure an accurate performance when the soundbar has been wall-mounted. In use the Dione astonishes with its low-end poise and slam, evocative ambience and smooth detail reproduction. To hear one is to want one.
