Bowers & Wilkins 804 D4

Reviewers found genuinely deep extension for this relatively compact tower, with measured output into the upper 20Hz region and powerful, gut-trembling low end in the Sound Advice system. The bass is repeatedly praised for its focus and freedom from boom or overhang, although The Absolute Sound heard the mid-bass as slightly restrained and StereoNET notes limits to ultimate power and extension.

The midrange is described as clean, open, spacious and highly detailed. StereoNET heard a more lithe, vibrant and revealing midband than earlier 804 models, while The Absolute Sound specifically praised the clarity of lower-midrange fundamentals.

StereoNET found the diamond-dome treble clear, airy, focused and explicit without harshness, calling it excellent even if not the very best heard. The Absolute Sound also heard striking openness, clarity and transient snap, but cautioned that the elevated upper-midrange and treble can make some recordings sound brighter and highlight digital artifacts.

Imaging is the speaker's standout achievement. The Absolute Sound called its soundspace presentation the best heard below $20,000, praising its ability to detach images from the cabinets, portray depth, and create a more natural vertical fade; StereoNET likewise found its image precision extraordinary for a conventional box speaker.

Reviewers describe lively transient response, strong musical timing and convincing contrast between soft and hard percussive strikes. It handles low-level listening and broad swings well with sufficient amplification, though The Absolute Sound did not find its large-scale dynamics clearly ahead of every rival and felt its restrained bass balance makes it less ideal for hard-driving rock.

The 804 D4 receives strong praise for its elegant, substantial construction, including the curved multi-layer wood cabinet, aluminium spine, solid plinth and isolated Tweeter-on-Top assembly. Reviewers highlight its attractive finish and rock-solid physical presence, while the internal compartmenting and separate tweeter enclosure reflect serious attention to resonance control.

At approximately $15,000 per pair, the 804 D4 is plainly a premium purchase, and Sound Advice notes that a full system built around it demands serious commitment. Even so, StereoNET considers it a compelling modern high-end music maker that remains well below flagship pricing, while The Absolute Sound's class-leading imaging assessment gives prospective buyers a clear reason to audition it against similarly priced rivals.
