Hertz Mille Pro 6.5" Coaxial 2-Way Speakers

The coax tweeter concentric to the woofer of the MPX 165.3 car audio coaxial speakers allows for one single linear-phase emission point, for a natural timbre providing a detailed sound stage. Thanks to the “Center Tuning Duct” geometry, the tweeter resonance frequency is especially low and the employment of damping materials for the inside provides for a linear acoustic emission. The acoustic lens optimizes its off-axis response, which is typical with door installation of coax speakers; besides, the 36 mm diameter woofer generates deep and controlled bass frequencies.

• 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
• 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 midbass frequency. (Logo Boundary Free)
• Over-Sized Ferrite Magnet: combined with very low carbon content iron plates, for low distortion at high power levels.
• Basket: 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.
