The Denon Home 400 is a premium wireless smart speaker built for rich, room-filling music in living rooms, open-plan spaces and everyday listening areas. It delivers stereo sound from a single speaker, combining elegant styling with the flexibility of modern wireless streaming.
Dolby Atmos Music adds a broader, more immersive sense of space to compatible music, while the built-in height speakers help create a more dimensional listening experience. It is an inviting choice for listeners who want detailed sound without filling the room with separate hi-fi components.
Powered by HEOS, the Home 400 makes it simple to stream music, group compatible speakers across rooms and control playback through the HEOS app. Start with one speaker, then expand into a flexible multi-room audio system as your needs grow.
Stream from favourite services or connected devices using Wi-Fi, Bluetooth, AirPlay 2, USB or the analogue AUX input. Adjustable bass, treble, width and height controls make it easy to tailor the sound to the room and your listening preferences.
