improve the car audio tweeters which was considered a reference since
its first introduction into the market is a quite challenging task which
could only be performed by a continued evolution in time and maximum
care for each detail that might affect sound.
From these presuppositions the Hertz ML 280.3 Legend car audio speakers
has been born. Through the FEA simulations, the electro-acoustic
designers carried out an extensive research which led to the
optimization of the Tetolon dome geometry, to minimize distortion.
This optimization method led to a reviewed face plate geometry for
improved frequency response and lower distortion.
Another element of the tweeter especially important for sound is the
rear acoustic chamber: the designers performed an exhaustive research on
the geometry as well as on the employed damping material, achieving 50%
increase in overall volume, to extend response to lower frequencies
with 900Hz resonance frequency.
