Hertz Mille MPX 165.3Pro - 16.5cm coaxial

The coaxial tweeter, concentric with the woofer of the MPX 165.3 coaxial car speakers, enables a single linear-phase emission point that ensures detailed sound reproduction with a natural timbre.
Thanks to the geometry of the "Central Tuning Channel", the tweeter's resonance frequency is extremely low.
The use of damping materials on the inside ensures linear sound emission. 
The acoustic lens optimizes the lateral radiation behavior, which is typical of coaxial speakers installed in the doors.
The woofer with a diameter of 36 mm produces deep and controlled bass frequencies.
