The Signature Diamond is our way of celebrating 40 years' leadership in the loudspeaker business. It brings together our most advanced technologies to create a quality of listening experience that's unheard-of from a two-way speaker.

Set into the sculpted, cylindrical cabinet is a Kevlar® midrange/bass drive unit. A first-order crossover of individually-auditioned components provides a simple, pure signal path. But the crowning glory is the marble tube-loaded tweeter, whose dome of synthetic diamond delivers high frequencies with jaw-dropping precision and clarity.

No other material gets closer to the perfect behaviour of a hypothetical tweeter dome, one of infinite stiffness and zero mass. Created by crystallising a 'carbon frost' into the shape of the dome at temperatures approaching those of the sun's surface, the diamond dome makes the sweetest-sounding tweeter you've ever heard.

Only 500 pairs of white Signature Diamond were made. Stock are strictly limited.
