  4. Esotar3 Tweeter

Esotar3 Tweeter


The Esotar3 is the pinnacle of Dynaudio soft-dome tweeter design. It’s an evolution of the renowned Esotar2 found in the new Contour and previous Confidence series, and it is an advancement of the cutting-edge airflow-optimisation technology seen in the award-winning Esotar Forty anniversary-edition tweeter.


The Esotar3’s rear chamber is much larger to reduce resonance, damping has been further optimised, and there’s a super-strong neodymium magnet on board for greater sensitivity and control.


A lower resonant frequency means a shallower frequency overlap between the tweeter and the midrange driver, which you’ll hear as better integration between treble and mids. To put it in musical terms, whatever you’re listening to won’t sound as if it’s been divided into distinct ‘double-bass’, ‘trumpet’, ‘triangle’ areas. You get the whole picture; it’s like listening in enhanced colour.


All these design changes mean that Dynaudio's engineers were able to experiment with creating a tweeter that doesn’t need heat-dissipating ferrofluid (which has been used in every Esotar tweeter up to now). In the Esotar 3, the combination of the more powerful magnet and the presence of the DDC Lens means a higher tweeter sensitivity. More sensitivity means the tweeter can react with a lower input voltage. An added bonus is that it means it doesn’t get hot as fast, so it can play louder, just as clearly, for longer.


There’s also a special new component inside: the Hexis. This is a small inner dome that replaces the Esotar2’s felt ring for even greater control over resonances, while also smoothing out the high frequency response.


Before the Hexis, Dynaudio used a felt ring in the cavity behind the tweeter dome. This did a fantastic job of reducing unwanted resonances that would bounce back to the rear of the tweeter and affect its output. However, thorough measuring showed that they could do better when it came to avoiding absorbing high-frequencies.


The dimpled plastic inner dome of the Hexis eliminates those unwanted standing waves, as well as doing some incredibly clever work when it comes to stopping driver movement the moment the music signal stops. If dome resonance is halted, timing improves, imaging improves, detail improves and so does your listening experience. 


So what does this all result to? Higher detail-resolution, improved clarity and even better dynamics. Quite simply, The Esotar3 is the best tweeter Dynaudio has ever produced.
