950 watts of room-filling Devialet sound
The Dione pumps 950 watts of power through 17 custom neodymium drivers — nine full-range aluminum drivers and eight aluminum long-throw subwoofers — yielding a generous 24Hz to 21kHz frequency response and a room-shaking 101dB maximum SPL. Driven by proprietary Devialet technologies, the Dione houses a quad-core ARM Cortex-A53 processor, along with an incredibly lucid 24-bit/96kHz DAC, ensuring thunderous infrabass and crystal-clear high end. When we fired up the Dione here at Sweetwater, we were duly impressed; as far as all-in-one soundbars go, it packs a tremendous punch!

Beyond that, the Dione features multiple listening modes — Movie, Spatial, Music, and Voice — optimized for your specific content. Finally, the Dione’s patented Orb center channel mechanically and acoustically adapts to the soundbar’s position, either wall-mounted or placed on a piece of furniture.
