B&W Signature Diamond Floorstanding Speakers

Here we have a pair of limited edition anniversary loudspeakers from British company Bowers & Wilkins. Just 1,000 pairs of the Signature Diamonds were made – 500 of them being in White and the others in the glorious gloss finish Wakame wood veneer as we have here. They are in good condition noting a couple of blemishes as shown in our product photographs. They will be professionally packaged and come with an accessory box which includes the manual and spikes plus our regular three month warranty,
Bowers & Wilkins Said….
Signature Diamond is our way of celebrating 40 years in business. Yes, we know; diamonds should be reserved for 60th anniversaries. But it wouldn’t be a B&W speaker if it were not ahead of its time.
Our diamond is a tweeter dome whose reproduction of high frequencies is as near perfect as it is physically possible to achieve. Encasing it in marble, setting it on a striking, plinth-like cabinet and partnering it with our Kevlar® bass / midrange driver hasn’t simply fashioned something akin to sculpture. It has created a sound so immediate, so detailed,
so textured, you’ll want to touch it. There isn’t a finer two-way loudspeaker in the world, to our knowledge. And, when we get around to celebrating our 60th anniversary, we could still be saying the same thing.
Kenneth Grange, architect of the Signature Diamond’s sculptural simplicity, is one of the world’s most accomplished product designers. Originally a draughtsman in an architect’s office and briefly an exhibition designer, his career took off when Kodak asked him to design their Instamatic camera. Many of his designs became familiar items, such as his food mixers for Kenwood, razors for Wilkinson Sword, pens for Parker and British Rail’s InterCity 125. Since designing
the ultra-distinctive DM6 in 1976, Kenneth has designed numerous speakers for B&W, of which the latest is the Signature Diamond.
The Signature Diamond is available in a choice of two finishes: minimalist white or a ‘designer’ wood veneer called
Wakame. Its resemblance to the edible seaweed is brought out by the gloss lacquering and polishing process, after
which it looks good enough to eat.
