Hertz Mille Pro Black 6.5" Car Speaker

Model #: MPX 165.3

• Concentric coaxial tweeter built in the woofer voice coil, achieving one single point of emission, to re-create the virtual sound-stage like in live music performances.
• 20 mm voice coil Tetolon fiber soft dome tweeter, featuring “Center Tuning Duct” geometry, for lower resonance frequency and reduced harmonic distortion.
• Tweeter support working as a rear chamber, sized for low Fs, to ensure a well damped high pass frequency roll-off, allowing low cut-off frequency crossover point.
• 36 mm pure copper woofer voice coil wound on a Polyamide former, for outstanding power handling and dynamic compression-free reproduction.
• Pressed-pulp cone with cotton fibers, combining stiffness and lightweight for a wide frequency response. Cone profile geometrically refined to perfectly match with the tweeter emission ensuring phase consistency in the crossover area.
• “Boundary Free” rubber surround, for improved efficiency and wider mid-bass frequency.
• Over-sized ferrite magnet combined with very low carbon content iron plates, for low distortion at high power levels.
• Low mounting depth, acoustically transparent aluminum alloy basket with elegant diamond cutting and featuring the aluminum Hertz logo.
• Anti-vibration rubber magnet cover, to damp spurious vibrations.

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.
