Hertz Mille Pro MPX 165.3 6.5" 16.5cm Car 2 Way Coaxial Speakers 100w RMS

165 (6.5) mm (in.) | Coaxials | 200 W | 4 Ohm. Extreme dynamics, unlimited power handling, realistic sound stage

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.

• 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.
• WEETER 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 aluminium alloy basket with elegant diamond cutting and featuring the aluminium Hertz logo.
• ANTI-VIBRATION RUBBER MAGNET COVER: to damp spurious vibrations.

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.

• 1. 38 mm pure copper woofer voice coil wound on a Polyamide former for exceptional power handling and dynamic compression-free reproduction.
• 2. Pressed-pulp cone with cotton fibers material, combining stiffness and lightweight for a wide frequency response.
• 3. Large rubber surround designed for long throw and optimal sound damping.
• 4. Over-sized ferrite magnet combined with very low carbon content iron plates, for low distortion at high power levels.
• 5. Aerodynamic thus acoustically transparent aluminium alloy basket, eliminates rear wave reflections.
• 6. Anti-vibration rubber magnet cover, damps spurious vibrations.
• 7. 28mm voice coil Neodymium Tetolon fiber dome tweeter, for undistorted mid-frequency reproduction.
• 8. 20mm voice coil Neodymium Tetolon fiber dome super tweeter, to naturally compensate for drop-off in frequency response due to speaker horizontal installation.
• 9. Tweeter faceplate with geometry optimized with FEM (Finite Element Modeling) simulations, to provide excellent off-axis frequency response up to 24kHz by perfectly mixing the two tweeters’ emission.
• 10. Full protection metal mesh grill featuring the aluminium Hertz logo and attractive look mineral powder coated inner grill are included for several install combinations.
