Just underneath the precision-coated dome sits an inner dome: the Hexis. This ingenious device is close enough to the back of the diaphragm that it stops unwanted resonant frequencies reflecting back to the rear of the playing surface. It smooths out the frequency response for clearer, cleaner, sweeter treble – meaning more detail. The Cerotar is powered by a brand-new strontium carbonate Ferrite+ ceramic magnet system that gives it more sensitivity. Down at the bottom are two 18cm Esotec+ woofers. Like the Cerotar tweeter, they use trickle-down technology from the Contour and Confidence families to bring as much of that high-end DNA to Evoke as possible.
The Evoke 50 speaker uses copper in its woofer. That’s because these are pure bass drivers – they don’t need the fleet-footed agility of a dedicated midrange unit, so we were able to give them more moving mass. The 0.4mm diaphragm is the same, though, as is the Ferrite+ ceramic magnet.
Each speaker cone is crafted from a single piece of MSP. This makes them exactly the right amount of rigid – and means far less physical distortion when they’re playing. It also gives a super-solid physical connection to the glass-fibre voice-coil former on the back (it’s glued directly under the Balance Ribs you’ll see around the centre), which means more of the coil’s motion energy is transferred to the diaphragm. And, for extra versatility they offer three levels of tuning: fully open, half-open and fully closed, so you can tailor the speakers’ bass performance to their position and your room.
Evoke 50 is the only speaker in the family to have a dedicated midrange driver, so the engineers in Dynaudio Labs decided to make it a little bit special. The 15cm unit they chose is derived directly from the high-end Contour range – which means a powerful neodymium magnet, a 0.4mm-thin diaphragm and a glass-fibre voice-coil former with a trademark Dynaudio aluminium voice-coil.
