Verdict and Definition: What the 800 Series Diamond D5 Actually Is
The Bowers & Wilkins 800 Series Diamond D5 is a family of high-end reference loudspeakers that refine cabinet rigidity, driver motor systems, and crossover networks over the previous D4 generation to deliver clearer transparency, higher resolution and more controlled resonance for discerning audiophiles who are willing to pay steep prices for incremental but audible gains in fidelity. From our exclusive listening sessions comparing each D5 model with its direct D4 predecessor, the bottom line is clear: this is a meaningful high-end speaker upgrade, but one that rewards careful system matching and quality recordings more than casual listening. Positioned as luxury loudspeakers, the range stretches from the two-way 805 D5 at £10,000 / USD 15,000 (approx. RM69,000) to the flagship 801 D5 floorstander at £43,000 / USD 65,000 (approx. RM299,000), firmly targeting buyers who treat their system as a long-term reference rather than an impulse purchase.
Design and Engineering Changes: Cabinet, Drivers and Crossover
At a glance, the new Bowers Wilkins 800 D5 models look like modest cosmetic evolutions of the D4 series, with updated finishes such as stealth black, dark walnut, light walnut and warm white and more elegant plinths on the floorstanders. The familiar curved cabinets, midrange pods on larger models and tweeter-on-top architecture remain, because the brand sees no reason to alter proven acoustic geometry. The genuine high-end speaker upgrade lies beneath the skin: D5 cabinets are more rigid thanks to improved bracing and increased use of aluminium structural elements, including reworked plinths designed to tighten resonance control and rigidity while improving visual presence. There are revised motor systems for mid/bass and bass drivers, plus tweaks to the tweeter unit aimed at improved transparency, all supported by updated crossovers using better-quality components and improved internal wiring. According to the company’s engineers, "just about every part of the new range has been revised".
Pros
- More rigid D5 cabinets with extra aluminium reduce resonance and improve clarity compared with D4 predecessors.
- Revised motor systems and tweeter tuning deliver higher transparency and resolution for premium speaker comparison buyers.
- Updated crossovers and internal wiring support cleaner signal transfer within this luxury loudspeaker review context.
Cons
- Any shortcomings in source material become more apparent, making poor recordings less forgiving on the 800 D5.
- Steep pricing from £10,000 / USD 15,000 (approx. RM69,000) to £43,000 / USD 65,000 (approx. RM299,000) limits accessibility.
Sonic Character Across the 800 D5 Lineup
Listening to the entire Bowers Wilkins 800 D5 series against its D4 predecessors – ten pairs in total – reveals a consistent tonal character but a clear generational upgrade in acoustic performance. The smaller 805 D5 two-way standmount, priced at £10,000 / USD 15,000 (approx. RM69,000), displays the same essential balance as the 805 D4, yet with noticeably sharper focus and more insight into low-level detail on our test tracks from Harry Belafonte, Phoebe Bridgers and Agnes Obel. At the other end of the premium speaker comparison, the mighty 801 D5 floorstander at £43,000 / USD 65,000 (approx. RM299,000) shows what the new architecture can do when fully unleashed: transparency and resolution are described as exceptional, making it easy to hear deep into mixes and exposing recording quality and upstream electronics without restraint. While the D5 models remain faithful to the 800 Series DNA, they feel more revealing, more controlled and more explicit about what is fed into them.
Trade-offs, System Matching and Real-World Use
The exclusive listening sessions used a serious reference chain, including a high-end Denon DP-S1 CD transport feeding an MSB Platinum Diamond DAC IV/Diamond Power Base and a Gryphon Commander preamplifier driving 225-watt Class A Apex monoblocs, underscoring that these speakers are designed as premium reference tools rather than forgiving all-rounders. In that system, the 800 D5 lineup showed an appreciable step ahead of the D4 generation in terms of clarity and refinement, but they also highlighted any issue in recordings or electronics, so owners should expect to invest in high-quality sources and amplification. Any shortcomings in source material become more apparent on the D5 series, which is a double-edged sword: thrilling with well-recorded music, less kind to flawed masters or compressed files. Provided you feed them a strong enough signal, there is little to complain about in pure performance, yet buyers should understand that this luxury loudspeaker review concerns speakers that expose systems rather than hide them.
How the 800 D5 Compares with More Attainable Hi-Fi Speakers
For context in a broader premium speaker comparison, it is useful to look at a well-regarded mid-priced floorstander such as the Dali Sonik 5. The Sonik 5 are compact two-way towers with a 29mm soft dome tweeter, two 13cm pulp/wood fibre mid/bass drivers, rear port, single-wire crossover, 88dB sensitivity, 6-ohm impedance and dimensions of 82.6 × 16.2 × 27cm, weighing 10.8kg. Their internally braced MDF cabinets use high-grade laminate in four finishes (natural oak, white, walnut and black ash), and they cost £899 / USD 1,800 (approx. RM8,280) / AUS$1749, positioned just below the award-winning Fyne F501E at £999 / USD 1,299 (approx. RM5,977) / AU$1999. At a similar price, the larger Fyne F501E offer deeper bass but lose some precision, showing how even at modest levels buyers juggle space, cost and quality. Compared with the Bowers Wilkins 800 D5, these floorstanders strike a balance between convenience and quality, rather than absolute transparency.
| Spec | B&W 805 D5 | Dali Sonik 5 |

| Cabinet construction | Curved, heavily braced cabinet with significant aluminium elements for rigidity and resonance control | Internally braced MDF cabinet with high-grade laminate finish in four colours |
| Drive units | Revised mid/bass and tweeter motor systems for higher transparency | 29mm soft dome tweeter, 2 x 13cm pulp/wood fibre mid/bass drivers with rear port |
| Sensitivity / Impedance | Not specified in the D5 listening report | 88dB/w/m, 6 ohms nominal |
Buy if / Skip if
- Buy the Bowers & Wilkins 800 Series Diamond D5 if you want a luxury loudspeaker review benchmark that reveals every nuance and flaw in your recordings and electronics, and you are ready to invest in matching reference-grade sources and amplification to exploit their transparency.
- Skip the Bowers & Wilkins 800 Series Diamond D5 if your music collection is dominated by low-quality or heavily compressed recordings, because any shortcomings in the source material are more apparent and you may find the honesty tiring over time.
- Buy the Bowers & Wilkins 800 Series Diamond D5 if you already own D4 models and value incremental fidelity gains, since the latest generation is an appreciable step ahead of its direct predecessors in resolution, cabinet control and overall refinement.
- Skip the Bowers & Wilkins 800 Series Diamond D5 if your budget sits closer to £899 / USD 1,800 (approx. RM8,280), where something like the compact Dali Sonik 5 offers a pleasing balance of convenience, cost and quality rather than ultimate transparency.
- Buy the Dali Sonik 5 if you need floorstanding speakers that fit small spaces, thanks to their petite 82.6 × 16.2 × 27cm footprint, internally braced MDF cabinets, and finishes designed to blend into most living rooms.
- Skip the Dali Sonik 5 if you are unwilling to spend time on careful placement, because they sound best at least 0.8m from the rear wall with minimal toe-in and can become bass-heavy or too bright when positioned poorly.
