Meet the Denon Home 400

The Denon Home 400 Wireless Smart Speaker is Denon’s larger-format premium wireless speaker for listeners who want fuller stereo sound, more scale, and a more immersive presentation than compact smart speakers can typically provide. With a six-driver array that includes dual height speakers, built-in HEOS streaming, and Dolby Atmos Music capability, it is engineered to fill larger spaces with richer, wider, and taller sound while keeping setup and control straightforward.

Practical advantage: start with one premium speaker for substantial room sound, then expand later with stereo pairing or broader HEOS multi-room integration.

Highlights & Benefits

• Bigger, more dimensional sound — the six-speaker array is designed to produce powerful stereo playback with greater scale and immersion than smaller one-box wireless speakers.
• Dolby Atmos Music support — built-in dual height speakers add a vertical dimension for a more spacious and lifelike soundstage from a single speaker enclosure.
• Premium Denon tuning — Denon states each Home product is precisely tuned in Japan by the Denon Sound Master for full, detailed sound that remains engaging across a wide range of music.
• High-resolution streaming — stream over Wi-Fi in high resolution, including lossless playback from compatible services and formats such as DSD.
• Flexible everyday connectivity — play through Wi-Fi, Bluetooth, AirPlay 2, aux input, or USB, depending on how you listen and what sources you use.
• Expandable premium ecosystem — the Denon Home 400 Wireless Smart Speaker is built for listeners who want a premium standalone speaker today and a flexible HEOS-based system tomorrow.

Technology & Design

Six-driver architecture with height channels — Denon positions the Home 400 as a more immersive all-in-one speaker, using six drivers including two up-firing units to create a larger and more dimensional presentation.

Powered by HEOS™ — HEOS provides app-based setup, streaming service access, multi-room grouping, and system expansion across compatible Denon and Marantz products.

High-resolution wireless playback — Denon highlights support for high-resolution streaming over Wi-Fi, including lossless playback from leading services such as TIDAL, Qobuz, and Amazon Music HD.

Placement and tonal control — built-in EQ lets you adjust bass, treble, and placement settings so the speaker remains balanced whether it is on a console, shelf, or sideboard.

In daily use, the Denon Home 400 Wireless Smart Speaker is designed to deliver more scale, more presence, and a more immersive experience than compact wireless speakers while remaining easy to live with.
