Der zum Tieftöner der koaxialen Auto-Lautsprecher MPX 165.3 konzentrische koaxiale Hochtöner ermöglicht einen einzelnen linearphasigen Emissionspunkt, der mit einer natürlichen Klangfarbe für eine detaillierte Klangwiedergabe sorgt. Dank der Geometrie des „Zentralen Tuning-Kanals“ ist die Resonanzfrequenz des Hochtöners extrem niedrig. Die Anwendung von Dämpfungsmaterialien auf der Innenseite sorgt für lineare Schallemission. Die akustische Linse optimiert das seitliche Abstrahlverhalten, was für koaxiale, in den Türen installierte Lautsprecher typisch ist. Der Tieftöner mit dem Durchmesser von 36 mm erzeugt tiefe und kontrollierte Bassfrequenzen.

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.
