Devialet Dione Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓Dedicated height channels (5.1.2) for Dolby Atmos, not only virtual processing
- ✓A dedicated centre channel for dialogue
- ✓HDMI eARC carries lossless Dolby TrueHD and Atmos from the TV
- ✓Wi-Fi streaming with AirPlay 2, Spotify Connect
- ✓Room correction tunes the sound to where it is placed
- ✓Dialogue enhancement
- ✗No DTS:X, so DTS soundtracks play without their height layer
- ✗No rear speaker option, so surround stays virtual
- ✗At 3.63 in tall it can block the bottom of a TV sitting low on its stand
Channels and Surround Sound
The 5.1.2 badge means 5 ear-level channels (left, centre, right and 2 for width or surround), 1 subwoofer channel, 2 height channels firing at the ceiling. It decodes Dolby Atmos.
Subwoofer, Rear Speakers and Mounting
It cannot add rear speakers. Wall-mountable: Yes (no bracket supplied).
Connections
The Devialet Dione has HDMI eARC to the TV - the connection that carries lossless Dolby TrueHD and Atmos from the TV's own apps and inputs; optical digital input.
Streaming, Control and Sound Modes
Wi-Fi (2.4, 5.0 GHz), with AirPlay 2, Spotify Connect; Bluetooth; app control (Apple iOS, Android). Sound features: dialogue enhancement, automatic volume levelling, room correction.
Size and Which TV It Suits
The bar measures 47.25 x 3.63 x 6.56 in (W x H x D), or 1200 x 92 x 167 mm, and weighs 26.4 lbs. It is no wider than the screen of a 55-inch TV (47.9 in wide) or larger, which is where a soundbar looks in proportion. At 3.63 in tall, check the gap between the stand and the bottom of the screen: on many TVs with feet at the ends it is under 3 inches, and the bar would block the picture or the IR receiver.
