Denon Home 400 Wireless Smart Speaker

The Denon Home 400 represents uncompromising sound in its most powerful form. As the largest model in the Denon Home series, this wireless smart speaker combines impressive power reserves, state-of-the-art streaming technology, and an elegant design into an audiophile package that effortlessly fills any room.

Sound that fills rooms

The Denon Home 400 features a sophisticated six-driver system that delivers an exceptionally wide and dynamic soundstage. Two precisely tuned full-range tweeters, powerful 4.5-inch woofers, and integrated 1-inch height speakers work together to create a detailed, spatial sound field – ideal for playing Dolby Atmos music.

Each individual driver is controlled by its own amplifier. The result is impressive precision, clear layering, and a commanding presence that effortlessly fills even larger rooms with sound.

Fine-tuning at the highest level

Like every speaker in the series, the Denon Home 400 was personally tuned by the Denon Sound Master. The goal was a sound signature that combines naturalness, warmth, and rich detail. Voices sound tangible, instruments authentic – music gains depth and expression.

Streaming diversity without compromise

The Denon Home 400 offers maximum flexibility in music playback. Whether directly from your favorite streaming services or from local sources – your music is always just a tap away.

Support is provided to, among others:

• Wi-Fi streaming via services like TIDAL, Qobuz and Amazon Music
• Bluetooth for spontaneous connections
• AirPlay 2 for integration into Apple systems
• USB port for local music libraries
• AUX input for classic playback devices

The proven HEOS® app ensures intuitive control and makes setup possible in just a few minutes.

Experience High-Resolution Audio

With support for high-resolution audio formats, the Denon Home 400 plays music with impressive detail. Even demanding formats like DSD can be played back via USB or network sources. This allows you to hear your favorite music exactly as it was intended – pure and nuanced.

Multiroom – flexible and scalable

As part of the HEOS multiroom system, the Denon Home 400 adapts flexibly to your listening habits. Create individual zones or group multiple speakers for a synchronized sound experience throughout your home.

Whether you choose different music in each room or a continuous soundtrack – you retain control at all times.

Expandable to a home cinema

The Denon Home 400 can do much more than just play music. Combined with other components from the series, it can be used to create a powerful, wireless home theater system.

Pair two speakers for an impressive stereo setup or expand your system with the Denon Home Sound Bar 550 and the Denon Home Subwoofer to create a full 5.1 ensemble – all without complicated wiring.

Design with ambition

The Denon Home 400 also sets standards in terms of appearance. Clean lines, high-quality materials, and an elegant design make it a stylish statement in any living space. The discreet integration of modern controls underscores the premium character of this speaker.
