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.
