Hertz Mille Pro MPK 163.3 - Speaker System

The three way Hertz Mille Pro MPK 163.3 car audio speaker system is dedicated to those who want the best: the Mille Pro MP 70.3 midrange featuring Neodymium double magnets inside the coil produces an enthralling mid range, perfect to combine with the powerful mid-low of the MP 165.3 woofer as well as with the detailed high range of the MP25.3 tweeter.

The 20 mm coil of the MP 70.3 maximizes the dynamics; the V-cone® profile enhances off-axis dispersion and the Boundary Free Surround allows for a wider extension towards the low frequency range.

The dedicated MPCX 3.3 crossover provides optimized crossover points to exploit the midrange remarkable extension using ultra-selected components.

Hertz Mille Pro MPK 163.3 - Product Features

MP 25.3:

• Tetolon fiber soft dome, for a natural yet detailed reproduction of musical nuances.
• “Center Tuning Duct” geometry, for lower resonance frequency and reduced harmonic distortion.
• High density flux Neodymium magnet, optimized for utmost control during high energy dynamic transients in the mid-high frequency range.
• 25mm ferrofluid-cooled mobile voice coil.
• Rear chamber filled with selected damping material and sized for lower Fs, to ensure a well damped high pass frequency roll-off, allowing low cut-off frequency crossover point.
• Faceplate featuring FEM (Finite Element Modeling) optimized geometry, for high linearity in off-axis installations.
• Wide array of installation accessories, for an easy OEM integration.

MP 70.3:

• Symmetrical dual Neodymium magnet structure specifically developed with FEM (Finite Element Modeling) simulations, for superior dynamics and control.
• 20 mm CCAW double layer voice coil wound on a Polyamide former with 8 decompression holes, for exceptional power handling and compression-free reproduction.
• Exponential V-cone® profile pressed-pulp cone with cotton fibers, combining stiffness and lightweight for a wide frequency response. Cone profile geometrically optimized for utmost linearity and dispersion in the mid-high frequency range.
• “Boundary Free” rubber surround, for better efficiency and wider mid-bass frequency.
• Anti-vibration rubber magnet cover, to damp spurious vibrations, removable to fit limited mounting depth installations.
• Acoustically transparent aluminium alloy basket with elegant diamond cutting and featuring the aluminium Hertz logo.
• Full protection metal mesh grill featuring the aluminium Hertz logo and attractive look mineral powder coated inner grill are included for several install combinations.

MP 165.3:

• Pure copper voice coil wound on a Polyamide former for high power handling combined with very low intermodulation distortion of vocals.
• Exponential V-cone® profile pressed-pulp cone with cotton fibers, combining stiffness and lightweight for a wide frequency response. Cone profile geometrically optimized for utmost linearity and dispersion in the mid frequency range.
• “Boundary Free” rubber surround, for improved efficiency and wider mid-bass frequency.
• High density flux ferrite magnet combined with very low carbon content iron plates, for low distortion at high power levels.
• Low mounting depth, acoustically transparent aluminium alloy basket with elegant diamond cutting and featuring the aluminium Hertz logo.
• Full protection metal mesh grill featuring the aluminium Hertz logo and attractive look mineral powder coated inner grill are included for several install combinations.

MPCX 3.3:

• Two-position (0 / +2 dB) switch for tweeter & midrange level adjustments, to fine-tune the transducers emission according to their installation position.
• 100V extremely high quality bi-metallized polyester film capacitors in the tweeter section, for maximum sound transparency and neat hi-frequencies.
• 1mm pure copper wire low series resistance inductors, for low dissipation losses on the woofer section where high transient currents are demanded.
• Compact footprint design for easy installation, with top vent grille for efficient heat dissipation.
