Each speaker’s single 14cm long-throw mid/bass driver is made from MSP (Magnesium Silicate Polymer). The diaphragm is 0.4mm thin, provides exactly the right combination of lightness, stiffness and damping to ensure optimum performance. It’s made of one piece (the dust-cap is part of the playing surface), and is bonded directly to the rigid glass-fibre voice-coil former directly under the Balance Ribs you’ll see around the centre dome.
The 38mm voice-coil itself is made from aluminium, making it extremely light. That means we can use more windings. More windings gives us more control over the cone’s movement, which means more control over the sound – even at high volumes and high frequencies. It’s kept stable, centred and true by the Nomex spider (the circular spring assembly that stops the cone moving when it shouldn’t, and lets it move when it should).
Up top is the brand-new 28mm Cerotar soft-dome tweeter. Our engineers looked behind the curtain of the award-winning Special Forty and money-no-object Confidence tweeters and cherry-picked some key technologies to bring to Evoke. The headline-grabbing component is the Hexis – an ingenious inner dome that refines the airflow behind the playing surface to smooth-out its frequency response and eliminate unwanted resonances. The new motor system uses strontium carbonate Ferrite+ ceramic magnets for improved sensitivity.
An ingenious inner tweeter dome that further smooths out the tweeter’s frequency response and minimises resonances – so all you get are the desirable ones. You’ll also find Hexis in the all-new Confidence.
