Hertz Mille Pro MP 70.3 3" Midrange Speaker

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.

• V-CONE®: The exponential profile gets very close to the perfect one, providing exceptional dispersion.
• Boundary Free Surround: This technology provides the ability to achieve wider emission surface of the cone compared to speakers with same diameter; that way, the cone manages to move a bigger mass of air, so it produces more acoustic pressure.
  This special surround is built from highly pure IIR butyl rubber, ensuring extraordinary thermal and mechanical linearity.

• 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® 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.
• BASKET: acoustically transparent aluminium alloy basket with elegant diamond cutting and featuring the aluminium Hertz logo.
• GRILLES INCLUDED: full protection metal mesh grill featuring the aluminium Hertz logo and an attractive mineral powder coated inner grill are included for several install combinations.
