HERTZ 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 36mm diameter woofer generates deep and controlled bass frequencies.

Features

• 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.
• 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.
• 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.
• Boundary free rubber surround: for improved efficiency and wider midbass frequency.
• 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.
