Denon Home 400 Wireless Smart Speaker – Charcoal

The Denon Home 400 is a wireless stereo speaker built to provide detailed sound and an immersive presentation from a single cabinet. Its six-driver array includes dedicated up-firing drivers for height information, supporting Dolby Atmos Music playback. Each driver has its own Class D amplifier, allowing the integrated system to control output without an external amplifier or speaker wiring. The Charcoal finish gives the cabinet a dark, neutral appearance.

The driver configuration uses two 19 mm tweeters, two 25 mm up-firing drivers and two 114 mm woofers. This layout combines high-frequency detail with low-frequency support and height channels. Denon lists stereo playback, high-resolution audio support and compatibility with a HEOS subwoofer, giving listeners options to pair it or extend the system as their room changes.

HEOS app control manages setup, playback and multiroom grouping. The speaker supports Wi-Fi, Bluetooth and AirPlay 2, so music can be sent from compatible services and personal devices. USB-C accepts stored music directly or can be used with an Ethernet adapter, while the 3.5 mm auxiliary input connects an analogue source such as a portable player or computer.

Controls include Quick Select presets, volume and playback functions. Voice assistant support is built in with microphone controls, and the app offers bass, treble, width and height adjustments to adapt sound to the room. Stereo pairing with a second compatible speaker can broaden the listening image. The cabinet measures 300 × 150 × 219 mm and weighs 4.2 kg.

Network playback depends on a stable home connection and compatible services or devices. Place the speaker on a stable surface with room around its acoustic openings. The HEOS app helps group rooms and manage playback.
