Short answer: a tie on sound quality. Both are rated 3.5/5 (#184 and #180 of 226 floorstanding speakers) at nearly the same price ($25,000 vs $25,000), so choose on features and fit.
What the Bowers & Wilkins 804 D5 does well: The smallest tower in the 800 Series Diamond D5: a 3-way with a 1” diamond dome tweeter, a 5” Continuum cone FST midrange and two 6.5” Aerofoil bass drivers. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the 800 D4 models it replaces.
What the Bowers & Wilkins 803 D4 does well: Incorporates the iconic all-aluminum Turbine Head dedicated midrange enclosure, isolating the 5-inch Continuum driver from cabinet resonances. Watch for: Pronounced treble elevation imparts a distinctly bright character that can fatigue ears on hot recordings.
Buy the Bowers & Wilkins 804 D5 or the Bowers & Wilkins 803 D4 on features: they are rated the same for sound quality at close to the same price.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Bowers & Wilkins 804 D5 3.2 to 3.8; Bowers & Wilkins 803 D4 3.3 to 3.7). Treat this verdict as provisional.

Bowers & Wilkins 804 D5: $25,000 per pair Estimated Bowers & Wilkins eBay
Older model: the Bowers & Wilkins 804 D4 (ranked lower, estimated 3.4/5). See every Bowers & Wilkins 800 Series generation.
Same family: the Bowers & Wilkins 805 D5 (bookshelf, estimated 3.3/5), the Bowers & Wilkins 803 D5 (larger floorstanding, ranked higher, estimated 3.6/5), the Bowers & Wilkins 802 D5 (larger floorstanding, ranked higher, estimated 3.7/5), the Bowers & Wilkins 801 D5 (larger floorstanding, ranked higher, estimated 3.8/5), the Bowers & Wilkins HTM82 D5 (smaller center, estimated 3.3/5) and the Bowers & Wilkins HTM81 D5 (larger center, estimated 3.4/5).
Pros: The smallest tower in the 800 Series Diamond D5: a 3-way with a 1” diamond dome tweeter, a 5” Continuum cone FST midrange and two 6.5” Aerofoil bass drivers. B&W rates it down to 19Hz (±3dB) in-room and 89dB sensitivity, so it fills a medium room without a subwoofer.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared directly with measured speakers; the rating is estimated from the 800 D4 models it replaces. Bowers & Wilkins’ house voicing, which the measured Bowers & Wilkins HTM81 D4 showed as a 4.9dB spread across the listening window, is likely to carry over, so expect a less neutral balance than similarly priced Revel or KEF models. The impedance falls to 3.0 ohms, which needs an amplifier that can deliver current.

Bowers & Wilkins 803 D4: $25,000 per pair Estimated Bowers & Wilkins eBay
Newer model: the Bowers & Wilkins 803 D5, ranked higher, estimated 3.6/5, released Jul 2026.
Older model: the Bowers & Wilkins 803 D3 (ranked lower, estimated 3.4/5). See every Bowers & Wilkins 800 Series generation.
Same family: the Bowers & Wilkins 805 D4 (bookshelf, estimated 3.2/5), the Bowers & Wilkins 804 D4 (smaller floorstanding, ranked lower, estimated 3.4/5), the Bowers & Wilkins 802 D4 (larger floorstanding, ranked higher, estimated 3.6/5), the Bowers & Wilkins 801 D4 (larger floorstanding, ranked higher, estimated 3.7/5) and the Bowers & Wilkins HTM81 D4 (center, rated 3.3/5).
Pros: Incorporates the iconic all-aluminum Turbine Head dedicated midrange enclosure, isolating the 5-inch Continuum driver from cabinet resonances. Dual 7-inch Aerofoil drivers achieve true sub-20Hz in-room extension (19Hz -3dB).
Cons: Pronounced treble elevation imparts a distinctly bright character that can fatigue ears on hot recordings. Heavy 137-lb cabinet and 3.0-ohm minimum impedance require high-current amplification.
