The Denon Home 400, part of the brand's revamped Home 2.0 range, is a premium home speaker priced at $599. It competes with notable brands like Sonos and Apple, offering impressive spatial audio capabilities through its six-driver setup, which includes Dolby Atmos support. Users can customize sound settings via the HEOS app, enhancing the audio experience with adjustable height and width features. The speaker's design is stylish and durable, with minimal visible plastic, making it suitable for various living spaces. However, it lacks built-in voice assistants, relying on Siri only if a HomePod is present on the same network. Overall, the Denon Home 400 is a strong contender in the premium speaker market, particularly for those seeking superior spatial audio quality and customization options.
