Description
Hertz Mille Pro MPX 165.3
The MPX 165.3 car audio coaxial speakers' coaxial tweeter and woofer enable for a single linear-phase emission point, a natural timbre, and a detailed soundstage. The tweeter resonance frequency is extremely low due to the "Center Tuning Duct" shape, and the use of interior dampening materials results in a linear acoustic emission. With door installation of cable speakers, the acoustic lens optimises its off-axis response. In addition, the 36 mm diameter woofer produces deep and regulated bass frequencies.
1. 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.
2. 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.
3. 36 MM PURE COPPER WOOFER VOICE COIL: wound on a Polyamide former, for outstanding power handling and dynamic compression-free reproduction.
4. 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.
5. “BOUNDARY FREE” RUBBER SURROUND: for improved efficiency and wider midbass frequency. (Logo Boundary Free)
6. OVER-SIZED FERRITE MAGNET: combined with very low carbon content iron plates, for low distortion at high power levels.
7. BASKET: low mounting depth, acoustically transparent aluminium alloy basket with elegant diamond cutting and featuring the aluminium Hertz logo.
8. ANTI-VIBRATION RUBBER MAGNET COVER: to damp spurious vibrations.
