Hertz Mille Series Component Car Audio Tweeter - ML2803

To improve a tweeter 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 ML 280.3 Legend 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 faceplate 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.


  • Neodymium magnet optimized with FEA simulations of the magnetic flux for utmost control and fast response to the transients
  • Extremely pure copper short circuit ring, for excellent very high frequency extension
  • Die-cast aluminium face plate with profile optimized with FEA simulations to improve frequency response and dispersion
  • Tetolon Fiber dome optimized with FEA simulations for lower distortion and improved dispersion in high frequency range
  • Frame structure and rear load chamber both derived from a CNC machined solid aluminium block, to ensure mechanically inert response to resonances
  • Rear chamber sized for only 900 Hz Fs: low Fs ensures wide extension in low frequency range and low distortion also in the crossing section, allowing a decreased cut-off frequency
  • High-density damping material underneath the dome, low-density absorbing material in the rear chamber, providing fluid acoustic emission and high damping in the low frequency response
