Hertz MPK 165.3 (Mile PRO 2-way System)

The MPK 165.3 car audio speakers system has been designed to ensure a wide low frequency response, even in cars with no space for a subwoofer. Thanks to the V-cone and Boundary Free Surround technologies the MP 165.3 woofer boast outstanding dispersion features and generates high SPL with compact dimensions. The dedicated crossover MPCX 2.3 has been designed to exploit the wide extension of the MP 165.3 woofers , ensuring a natural transition towards the MP 25.3 tweeter, for maximum natural acoustic emission. The 1mm low parasitic resistance copper filter coil of the woofer maximizes its efficiency. The MPCX 2.3 crossover features tweeter level (0/+2 dB) to calibrate the MP 25.3 acoustic emission level comparing it to the woofer one.

Hertz MPX 165.3 (Mile PRO 2-way Coaxial)

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.
