Denon Home 400 Streaming Speaker, Black (Each)

The Denon Home 400 is an active streaming speaker with HEOS Built-in, six dedicated drivers and upfiring height channels for Dolby Atmos Music from a single cabinet.

It's the living-room speaker of the Home series: wide enough to open up a full stereo stage, with height channels that make Atmos tracks noticeably more spacious, without you having to distribute several speakers around the room.

Why the Home 400?

Because six dedicated Class D amplifiers drive six drivers independently: two 19 mm tweeters, two 25 mm upfiring drivers for height, and two 114 mm woofers for the bass. That gives you a stereo stage with real depth and – with suitable streaming material – a Dolby Atmos Music experience straight from a single cabinet. HEOS Built-in, AirPlay 2 and Bluetooth cover every common streaming source, plus high-resolution audio support.

A microphone with an on/off switch allows voice control via Siri, but can be completely disabled if you prefer.

What you hear

A rich, room-filling sound with noticeable bass foundation and – thanks to the upfiring drivers – a hint of ceiling reflection on Atmos tracks. For a normal to larger living room, the Home 400 delivers more level and depth than you'd expect from a single speaker.

Who is the Home 400 for? (and who isn't it for)

Ideal as a standalone living-room speaker or as the basis of a multiroom system with genuinely high demands on sound and level. Straight talk: if you want maximum room-filling sound for very large, open spaces, go for the even bigger Home 600 – the Home 400 is the all-rounder in the middle, not a pure powerhouse.

Our verdict

The Home 400 is the speaker that covers most living-room demands with a single unit – music, Atmos streaming and multiroom included. At HD Zürisee in Wädenswil, we advise you on placement, stereo pairing and how it works together with your TV and subwoofer.

Frequently asked questions

What do the upfiring drivers on the Home 400 actually do?
They radiate sound toward the ceiling, creating a more spacious, more open impression with Dolby Atmos Music tracks – with no need to install separate ceiling speakers.

Is the Home 400 enough for a large living room?
For most living rooms, yes. For very large, open spaces, or when maximum level and bass are needed, the Home 600 is the more consistent choice.

Can I pair two Home 400s as a stereo pair?
Yes, via the HEOS app, two units can be linked as a stereo pair with separate channels – for an even wider stage in the room.

Does the Home 400 work without a streaming subscription?
Yes. Internet radio, your own network files and Bluetooth from your phone all work without a subscription. Spotify, Tidal or Deezer are additional options via the HEOS app.

Why buy the Denon Home 400 at HD Zürisee?
Because a living-room speaker of this size has to suit the room. We advise you on placement, level and how it works together with your TV or subwoofer, in person and independently of any spec sheet.
