About the Denon Home 400 Black
The Home 400 is the mid-sized model in Denon's Home wireless speaker lineup, built around six drivers — two 0.75" front-firing tweeters, two 1" up-firing drivers, and two 4.5" woofers — each powered by its own share of six discrete Class D amplifiers totaling 90 watts. The up-firing pair plays true Dolby Atmos Music from services like Amazon Music Unlimited and TIDAL HiFi through the HEOS app, delivering a genuinely immersive soundstage from a single standalone speaker. Two Home 400 units can also be paired for true left/right stereo.
The Home 400 connects over tri-band Wi-Fi 6E (802.11ax, 2.4/5/6GHz) for whole-home HEOS audio, set up through the free HEOS app, and its USB-C port can become a wired Gigabit Ethernet connection with an optional adapter for the most stable possible link (there's no built-in Ethernet jack). It streams Apple AirPlay 2 (with Siri asking to play Apple Music), Amazon Music, Spotify Connect, TIDAL Connect, Qobuz Connect, Pandora, SiriusXM, and TuneIn, and is Roon Ready. Built-in Bluetooth handles direct streaming from a phone or tablet, and it plays high-res files up to 24-bit/192kHz over the network.
There's no handheld remote or built-in voice assistant — the HEOS app (iOS/Android) is the hub for setup and daily use, switching between online music services, a personal library, and the speaker's Bluetooth or 3.5mm aux input, with quick access to Recent, Favorites, and New picks.
