Soft Dome Tweeter Esotar² 110
Dynaudio has relied on soft dome tweeters for reproducing natural
high frequencies since the company’s origins, having perfected
the soft dome principle. The Esotar tweeter design requires an
extremely time-consuming labor intensive process where the ne
fabric diaphragm is shaped into a dome and then treated with a
special precision coating.
The best material for a tweeter is experience: Dynaudio has earned a
reputation as a manufacturer of the nest high frequency drivers available
with its venerable Esotar tweeters, and the company has incorporated its
most rened technologies into the new Esotar² 110 reference automotive
tweeter – which purely lives up to the Esotar designation by offering the
most accurate, nuanced and detailed high frequency performance in the
world. The Esotar² 110 represents the state-of-the-art in tweeter design
while never exhibiting a shrill or harsh sonic character typical of metal or
exotic material tweeter designs.
The Esotar² 110 tweeter features a specially coated 28 mm (1.1") diameter
fabric dome, an ultra-lightweight voice coil, an extremely powerful neo-
dymium magnet, and an exceptional CNC-machined metal housing with a
newly-developed damping back chamber. The performance is highlighted
by extremely high power handling, effortless reproduction of dynamics,
absolute clarity, natural tonal balance and incredible resolution.
