Denon Home 400 Wireless Smart Speaker

The Denon Home 400 takes the familiar wireless speaker and gives it rather more ambition. Its clean, continuous design, soft-touch controls and choice of Stone or Charcoal finishes make it easy to live with, while the six-driver array gives it considerably more sonic authority than its compact footprint might suggest. Dual tweeters and 4.5-inch woofers are individually amplified for precise control, while built-in 1-inch height speakers add a sense of vertical dimension and bring Dolby Atmos Music to the party. The result is a broad, detailed and surprisingly immersive presentation, tuned by Denon’s Sound Master for the natural balance, warmth and refinement that make long listening sessions rather enjoyable.

Connectivity is equally well considered, with Wi-Fi, Bluetooth, AirPlay 2, USB-C and Aux-In covering everything from high-resolution streaming to the occasional direct connection. Through HEOS, you can stream services including TIDAL, Qobuz and Amazon Music, while lossless formats including DSD can be played from USB or NAS-connected devices. And, being a Denon Home speaker, it is designed to grow with the rest of the house: pair two wirelessly for stereo, group speakers into different rooms, or build a wireless 5.1 system with the Denon Home Sound Bar 550 and Denon Home Subwoofer. In other words, it is a speaker that manages to be pleasantly simple on the surface while offering rather more depth once you start exploring what it can do.
