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
Outstanding performance in a compact size; this is the target of Mille Pro car audio subwoofers. On the strength of knowledge acquired with Mille Legend, Hertz has optimized the production process to offer the Hertz Sound Experience to a wider audience using part of the technologies and materials of the flagship line.

The rigid cone is made by pressing paper pulp with the injection of mineral powders, the same construction technique used for the Legend range. The V-cone® profile increases rigidity, allowing the cone to function like a piston. Surround materials consist of high-purity IIR-butyl rubber. Like the Legend range the Mille Pro are also built with Boundary Free Surround technology allowing for a greater emission surface with equal diameter, generating higher sound pressure. The compact 6-spoke aluminum alloy anti-resonant basket is the same as the top model Legend and contributes to the mechanical damping and being absolutely transparent to the sound. The 65 mm quad layer voice coil is higher than 60 mm and wound in a TIL-P former, thus delivering high linear displacement. The impedance configuration improves versatility to match any amplifier system.

The air cooling and decompression system avoids the need for a centre hole on the bottom plate with three advantages. first up it enjoys better thermal inertia to ensure low operating temperatures during musical transients. Second is a maximization of the magnetic field induced to the coil with the same overall motor dimensions. Thanks to a greater amount of iron in the pole the likelihood of magnetic saturation decreases exploiting the maximum flux density generated from the magnet. Lastly it’s possibe to install the subwoofer right on the box wall, taking full advantage of its minimal dimensions. A damping rubber disk provided with the product secures the subwoofer to the box and ensures air exchange for the multiple vents on the bottom. The holes behind the voice coil winding and the multiple vents on the bottom plate ensure greater air exchange to the coil inner layers and work in synergy with an innovative assembly system. It forces the air to pass through the air gap to keep the coil operating temperature low, even with the most extreme musical programs. The terminal uses solid push connectors with an anti-short circuit cover provide ultra-low wiring resistance in low impedance configurations.

Design Features
– Ergonomic and compact design, specifically developed for sealed box enclosures starting at 17 litre volume.
– CCAW 65 mm quad-layer voice coil capable of handling 1200 W musical power.
– The impedance configuration improves versatility to match any amplifier system.
– Voice coil wound on TIL-P material with venting holes behind the winding. This combines efficient heat dissipation with a high Qms factor (low mechanical loss) for bursting dynamic sound.
– Exponential V-cone® with optimized geometry for high cone stiffness and strong resistance to deformation even at maximum excursions.
– Boundary Free IIR rubber surround, for higher SPL performance while keeping a nominal external diameter.
– Mineral-injected paper cone, for superior rigidity and damping.
– Extremely acoustically transparent anti-resonant aluminium alloy basket with six-spokes standing structure and built-in venting holes underneath the spider.
– CNC machined elegant diamond-cut basket edge featuring the Hertz logo.
– Terminal block accepting cables up to 8 AWG to provide ultra-low wiring resistance in low impedance configurations. A plastic cover prevents any accidental short-circuit.
– Possibility to secure the subwoofer to the box wall, taking full advantage of its minimal dimensions.
– High performance compact motor with a superior magnetic field transferred to the coil.
