Denon Home 400 – Six-Driver Stereo with True Dolby Atmos Height

The Denon Home 400 is a premium wireless smart speaker engineered for larger living spaces. Its custom six-driver array — including dedicated up-firing height speakers — delivers real Dolby Atmos Music with a three-dimensional soundstage that extends both wide and tall. Powered by HEOS and supporting Wi-Fi 6E, AirPlay 2, and Bluetooth, it's built for listeners who want immersive, room-filling audio without a complicated setup.

Key Features

Six-Driver Array: Dual wide-range tweeters, two 4.5-inch woofers, and two integrated 1-inch up-firing height speakers — each powered by its own amplifier.

Dolby Atmos Music: Up-firing drivers create real vertical dimension for spatial audio, not just a simulated effect.

HEOS Multi-Room: Group with other Denon or Marantz HEOS speakers, stream to multiple rooms, or build a 5.1 wireless home cinema with the Denon Home Sound Bar 550.

Wi-Fi 6E + AirPlay 2 + Bluetooth: Stable, high-bandwidth wireless across all platforms.

USB-C & Aux-In: Wired input for turntables, portable players, or any line-level source.

HEOS App Control: Stream Tidal, Qobuz, Spotify Connect, Amazon Music HD, or high-resolution files from NAS/USB.

Stereo & Surround Pairing: Two units pair wirelessly for true stereo; connects to Denon Home 550 soundbar for 5.1 surround.

Customer Benefits

Step up from a single-driver "smart speaker" to a genuine multi-driver stereo system with height. The Denon Home 400 fills larger rooms convincingly and remains the natural mid-point in the Denon Home ecosystem — powerful enough to anchor a living room, flexible enough to integrate into any HEOS setup.
