Product Information

Diamond is the hardest naturally occuring material in the known universe and as fans of Professor Brian Cox will know it also has many other interesting properties. One that he may not have mentioned has been put to good use in the B&W 802D Diamond loudspeaker – namely that it is the ultimate tweeter material. The 802D utilises a high frequency drive unit made from diamond for the sheer purity of sound that it can provide. The 802D shares many of the design principles with the superlative 800D models at the top of the 800 range. However, the 802D has been scaled down in size to make it more compatible in a more typical range of domestic rooms.

While the slimmer dimensions of the 802D Diamond make it an easier fit for living spaces, the basic design retains nearly all of the features of the top-of-the-range B&W 800 Diamond, including the teardrop form of the midrange head. Moulded from Marlan®, a synthetic, mineral filled resin, this granite-hard enclosure is sprayed with seven coats of lacquer and polished by hand until it’s as smooth as glass.

As with all of the speakers in the range, the 802 Diamond features the legendary Nautilus™ tapering tube drive unit technology. First pioneered on the trailblazing Nautilus speaker, the tubes work like horns in reverse, minimising colouration by soaking up excess sound energy from the back of the driver. So that all that emerges from the front is the most fully formed, focused and pristine sound.

In our own Audiofile Review extensive listening to the B&W 802D Diamond in a number of systems has led us to the view that the 802D and it’s larger brother the 800D are probably the best sounding loudspeakers in the known universe. We will have to leave any other explanations about the formation of diamond in a collapsing star to Brian Cox however.
