While many televisions have a good picture, their sound quality often leaves a lot to be desired. And even televisions that sound good can be enhanced with additional speakers. Soundbars and sound plates were developed for precisely this purpose. Our soundbar test shows that expensive does not always mean good...
Devialet Dione
950 W, 5.1.2 ChannelProduct details
Devialet Dione is a stunningly slim, intensely immersive soundbar featuring a range of Devialet's patented technologies. ACOUSTIC DEEPNESS: Seventeen independent high-end speakers, all equipped with Devialet's proprietary technologies, deliver deep infrabass and crystal-clear highs. With plug-and-play, you can enjoy a vivid, cinematic and audiovisual experience in a 3D, 5.1.2 configuration. THE SCIENCE OF DEEP BASS: Devialet Dione combines eight internal high excursion subwoofers in a push-push configuration based on SAM technology. The SAM algorithm, inherited from the Phantom, optimises the effect of the woofers and enables a wide sound angle for unmistakably deep bass. This configuration not only eliminates the need for a separate subwoofer, but also ensures that Devialet Dione delivers powerful low frequency effects with improved directivity. ALL-ROUNDING ACOUSTICS: With SPACE, Devialet Dione's proprietary 3D sound algorithm, you are immersed in your favourite movie, music or game in any environment. Immersion, redefined. SUDDENLY INAUDIBLE: With high performance in a compact form factor, Devialet Dione stands out in both design and sound quality and fades into the background when the action starts. The slim, central ORB pays tribute to the Phantom's famous aesthetics.

The unique design, the high-quality workmanship, the minimalist concept, the powerful bass range and the flexible alignment of the centre sphere are the flagship features of the Dione soundbar.
