Hertz Mille MPK1650.3 PRO System

The MPK 1650.3 car audio speakers system is the top of the range two way system of the Mille PRO line. The system uses the 28 mm diameter MP 28.3 tweeter inheriting all the technological features of the Mille Legend ML28.3. The geometry of the Tetolon dome maximizes the typical dispersion of off-axis listening. The rear acoustic chamber with damping material contributes to extend response to lower frequencies achieving a resonance frequency of only 900 Hz. In this way the crossover point between tweeter and woofer can be lowered, improving the sound image in the car dashboard. The massive Neodymium motor minimizes nonlinearity managing the music program with very dynamic transients. The CCAW (Copper Clad Aluminium Wire) voice coil guarantees an especially light weight and stiff moving assembly. These technological elements interact with each other, resulting in a high frequency extension of 28 kHz, a record for a tweeter featuring a 28 mm voice coil. An elegant and compact angled tweeter support is provided with the system: this allows easy installation both on the A-pillars and on the car dashboard. The correct angle of the tweeter improves the stereo image, essential for an engaging listening.

The MP 165P.3 woofer electroacoustic parameters have been forged to give it the pure and solid sound of an authentic mid-bass, designed for high dynamic systems. The voice coil with a generous 14 mm height, has a nominal 3 Ω impedance in addition to an increased power handling. These features provide the ability to maximally exploit the power of the Hertz HCP and HDP amplifiers as well as all the 2 Ω stable electronics. The ferrite 95 mm diameter magnet enables a +/-4.5 mm voice coil linear excursion, ensuring utmost control at all times. The Boundary Free Surround moves a bigger amount of air, and the V-cone® profile improves the offaxis dispersion, the real in-car listening condition. The sophisticated aluminium alloy basket neutralizes the undesired vibrations. 

The crossover MPCX 165.3 creates the optimal tone balance between the MP 28.3 tweeter and MP 165P.3 woofer. It features bi-metallic capacitors with polyester dielectric, for maximum acoustic transparency and air wound inductors built on pure copper wire with up to 1mm diameter eliminating saturation. It also mounts wire-wound type resistors with low parasite inductance. The two positions Hi-Contour control provides the ability to fine tune the system frequency response optimizing it according to the different speakers positions. Most of all, the listeners can achieve their favourite sound thanks to the three-position control for the tweeter emission level with 2 dB steps (+2/0/-2dB) attenuation.
