Evoke 50

If a pair of Evoke 50s in a room doesn’t say “statement of intent” we don’t know what does. Use them in stereo. Use them as part of an Evoke multi-channel home cinema system. However you listen to them the word ‘epic’ won’t be far from your lips.

Evoke 50 is a full three-way floorstander with a 28mm soft-dome tweeter a 15cm neodymium midrange driver and twin 18cm woofers.

Evoke 50 features Dynaudio’s Cerotar tweeter. It’s a ground-up design that uses key technologies from the award-winning Esotar Forty anniversary tweeter, the awesome Contour series and the all-singing, all-dancing tech-fest that is Confidence. Our engineers are very proud of it. As well they should be.

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, and more of those “hey, I don’t remember there being a triangle in this piece of music!” moments. The Cerotar is powered by a strontium carbonate Ferrite+ ceramic magnet system. That gives it more sensitivity, which, in musical terms, translates simply to ‘honesty’. You’ll hear just what you’re supposed to hear. And because it’s so smooth and natural, you can listen for hours without getting tired.

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 woofers are made from our own proprietary material MSP (Magnesium Silicate Polymer). We’ve been using it in our cones for decades – and we’ve yet to find anything that gives a better balance of lightness stiffness and damping. If it ain’t broke…

But while the Evoke 20 standmount speaker uses aluminium in its 18cm woofer Evoke 50 uses copper. 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. That means power and detail. It’s just one of the solutions arrived at through extensive analysis and simulation in our Jupiter measuring facility.

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.

Aramid fibre spiders keep everything centred and moving the way it should while the Contour-derived surround allows a longer throw ratio for greater punch.

And for extra versatility – if you rearrange your room or move house for example – the rear-firing bass ports have two-part foam plugs. 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.

The new Esotar Forty tweeter takes air-movement to another level. It moves the air in typically sweet fashion in front of the DSR (Dynaudio Secret Recipe) precision-coated soft-dome of course but there’s a lot of engineering going on behind it as well.

Take the new pressure conduit. It’s a shaped vent in the back of the hybrid magnet system that allows more space in the rear chamber. That space lets us pack in more damping material and reduces back-pressure while the shape itself optimises airflow coming backwards from the rear of the dome.

Then there’s the outlet the aero-coupled pressure-release system. It sits underneath the voice-coil and reduces unwanted pressure build-up that could affect its movement. Stopping those pockets of air from forming reduces resonance – and less resonance equals even greater potential for detail.

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.

Why neodymium and not the Ferrite+ of the woofers? Because it’s light and it’s powerful. Why aluminium and not copper? Again because it’s light (and lets us put more windings in the voice-coil for a given weight). That’s a combination that gives our team amazing control over how the driver responds – they were able to fine-tune it to integrate perfectly with the woofers and tweeter.

In fact the Evoke team did such a good job that you essentially are getting Contour-level performance out of this midrange driver.
