Floorstanding loudspeakers

At a first glance the new 800 D3 speakers are built around the same principles like their successful predecessors, 800 Diamonds. And in fact they are – only that everything is a bit more extreme here - the cabinet, drivers, materials and the way the speakers look. The changes paid off as the sound has improved too. A lot.

Function and form

Ease of use

The main cabinet is reversed: instead of a curved enclosure with a flat front baffle the 800 D3s have a U-curved front battle that is held together by a aluminum panel at the back. The panel also hosts bi-wirable speaker terminals. Internal plywood braces were replacced by MDF ones.

Aluminum heads: B&W’s proprietary Marlan heads for midrange and tweeter housings was replaced by aluminum to further reduce resonances. The midrange unit’s head has received a tappered look to better dissipate energy inside. All three driver compartments are ‘glued’ together via gel segments to eliminate the energy transfer.

New drivers: The 25mm diamond dome of the tweeter is made of, surprisingly, vaporized diamond. Traditional yellow Kevlar that has become synonymous with Bowers & Wilkins speakers is gone – now we have what they call 150mm Continuum cone. Also two Rohacell membranes of bass drivers have been replaced by 250mm “Aerofoil” cones of variable thickness with ‘better pistonic behaviour’. Alike the Kevlar or Rohacell the new materials are woven composites. The bass is supported by a down-firing port.

800 D3 are available at piano black, satin white and rosenut finishes.

Bass management


Bowers & Wilkins specifies the 800 D3 to be able to reach 15Hz (-3dB point). Looks great on paper and apparently – when I auditioned them - the speakers have no trouble to dig deep. Yet it is important to realize that at such low frequencies no music instrument operates. What happens below 20Hz is mostly just the ‘breathing bass’, a moving mass of air rather than a sound. Especially in smaller rooms such extension brings along more difficulties than benefits. When listening to Beck’s Missing from Guero album the bass was pumping and deafening, despite the speakers were placed far from boundaries in a >100sqm room. The bass, which I would describe as “subterranean” had its prevalent energy between 40-80Hz, which is where the most bass instruments are centered, with attack above 100Hz. However, when I cut off everything below 25Hz with an equalizer (steep roll-off applied) the sense of weight and scale was reduced. This also demonstrates the usefulness of having the extension down to 15Hz - but only when the acoustics of the listening environment allows. This should be the crucial element for your consideration if you plan to invest into 800 D3s.

Clarity & delicacy


I shared my listening room with a pair of 802 Diamonds for over two years so I know what to expect from Diamond Nautilus tweeter. It never disappointed – the highs were always immaculately transparent and extended with a tad of certain robustness but also a tad of forwardness at the same time. There is no doubt that the 800 D3 is in treble at least comparable if not better, yet I still can sense the same forwardness, as if the speakers were tuned to give extra air above 10kHz and extra presence to vocals above 1kHz. Though not bad for jazz divas and small ensembles it is quite challenging for some hard rock material – the result is maybe too much energy in those audio bands and the sound borders shrieky and piercing at occasional moments. The good thing is that this forwardness is balanced by the competent bottom end and the sense for scale. Still, make an effort to find a good matching amplifier if you plan to listen to rock music only.
From the sensitivity point (90dB) the Bowers & Wilkins 800 D3 are not difficult to drive, however their impedance curve is a bit wild so you will need a stable amplifier.

Tonal accuracy

Temporal resolution

I would say that the dynamics and overall coherence that is so successfully paired to the 800 D3’s transparency is what makes the speaker so different from the Bowers & Wilkins 800 Diamond. Opening lines of any instruments are amazing. The fiery rendition Liszt’s Hungarian Rhapsodies by Georges Cziffra is a great example. Each key stroke is like a detonation, Cziffra’s pianism is almost supernatural in its precision and speed and so are the 800 D3. Each note is virtually sculpted in a high transient contrast, no smear here. Is this because the Cziffra’s recording has been remastered on B&W speakers at Abbey Road for EMI’s Great Recordings of The Century series? Perhaps.
As far as the tonality is concerned I only have a small remark – during my listening sessions I had a feeling that the new 800 D3 favour slightly the upper part of frequency spectrum which lends a bit thinner (just a tiny bit) impression in comparison with its predecessor.

Spatial resolution

Soundstage width
Soundstage depth

Like with 800D and 800 Diamond if you want to achieve deep and wide soundstage with precise imaging it is necessary to invest money and time. The money will be needed to tame the acoustics of your room and time to finalize the positions of the speakers within it. It is not easy to balance them properly but it is worthwhile the effort. The 800 D3 play nice if you respect all the usual speaker placement recommendations but the play great if the placement is painstakingly fine tuned. You’ll be rewarded by a holographic soundstage with extra focus, extra depth and less overhang. The trade off is that the sweet spot is very narrow, limited to one listener at time.
Like their predecessors the Bowers & Wilkins 800 D3 are very egoistic speakers. B&W knows how to push audio industry limits and the world needs reliable benchmarks – that is why the speakers like the 800 D3 were made.
