Hertz Audio – The Embodiment Of Italian Electronic Acumen
In physics Hertz may just be a unit of frequency, the number of cycles per second as it were. In the realm of car audio however, the name Hertz is synonymous with quality that delivers. From the brand’s name through to the characteristics of its products; everything about Hertz reflects upon its performance oriented dogma though quality design. The enthusiasm for music vibrates within the Hertz team and lies at the heart of everything the company; hitherto Hertz has built an outstanding team of talented and passionate engineers who are committed to designing products at the top level of audio performance.

Mille Pro - Raising The Bar Rather Than The Budget
The Mille Pro range may reside just beneath the Mille Legend behemoths, nonetheless Hertz has cleverly borrowed plenty of the design ideologies and philosophies in order to product the Mille Pro. They represent accurate electroacoustic design conjoined with an innovative automated manufacturing process. The end result is a range boasting a great price to performance ratio, making the famous Mille technology affordable to a wider range of car audio enthusiasts.

Design Ideologies
All coaxials are not the same. The tweeter here is located concentric to the woofer of the driver, allowing for one single linear-phase emission point. This is conducive to 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, whilst the woofer generates deep and controlled bass frequencies.

Design Features
– Concentric coaxial tweeter. This is 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, this allows for a lower cut-off frequency crossover point.
3. 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. Cone profile geometrically refined to perfectly match with the tweeter emission ensuring phase consistency in the crossover area.
– Boundary free rubber surround. for improved efficiency and wider midbass frequency.
– Oversized ferrite magnet. Combined with very low carbon content iron plates, for low distortion at high power levels.
– The basket has a low mounting depth, is acoustically transparent aluminium alloy basket and is finished with elegant diamond cutting and featuring the aluminium Hertz logo.
– Anti-vibration rubber magnet cover. This acts to damp spurious vibrations.
