Diamond, not just a girls best friend but a music lovers too!

Why use diamond for tweeter domes? It may seem extravagant, but the move is simply an extension of B&W’s pursuit of the perfect loudspeaker. One element of our quest for the best is the development of drive units that neither add nor subtract from the signal. In a tweeter, that means creating a dome that remains rigid, exhibiting perfectly piston-like behaviour, as far up the frequency scale as possible. Best for this are materials with a high stiffness to density ratio - which is where diamond comes in.

Over the years, B&W has optimised the design of its aluminium tweeter dome to raise its break-up frequency and bring about a cleaner sound. But the material that gets closest to the behaviour of a hypothetical perfect tweeter – one with infinite stiffness and zero mass that can only exist in a computer - is diamond. Working with the world’s foremost industrial diamond producer, we’ve created the ultimate tweeter dome and the sweetest-sounding tweeter you’ve ever heard.
