Hertz MPS 250 S2 shallow subwoofer has been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box.MPS 250 is optimized to work in ultra-compact sealed boxesstarting from only 14 Lt (0.49 Cf). A typical example is a subwoofer enclosure under the rear bench of pickup trucks, where the space - and the height - are limited.Mille PRO shallow subwoofer have a depth/performance ratio never achieved before thanks to the impressive cone excursion capacity which is 20% higher than a traditional design.This exceptional target has been achieved thanks to the ingenious suspension group design featuring a dedicated support structure for spider and coil. This solution has allowed to move the magnetic group inwards, reducing the depth and at the same time maximizing cone linear excursion.

Outstanding performance in a compact size, this is the target of Mille Pro car audio subwoofers. On the strength of its know-how acquired with Mille Legend, the R&D team 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 MP 300 D4.3 cone is made by pressing paper pulp with the injection of mineral powders, the same construction technique used for Legend. 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 ML2000.3 and ML2500.3, the Mille PRO subwoofers are 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 ML 2500.3 and contributes to the subwoofer’s mechanical damping, being absolutely transparent to the sound.  The 65-mm 4-layer voice coil is higher than 60 mm and wound in a TIL-P former, thus delivering high linear displacement. The 4 Ω + 4 Ω DVC 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:- Better thermal inertia to ensure low operating temperatures during musical transients;- 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;- Possibility 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 10 vents on the bottom.The holes behind the voice coil winding and the 10 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 antishort circuit cover accepting cables up to 8 AWG to provide ultra-low wiring resistance in low impedance configurations (1ohm).   Size mm (in.) 300 (12) Power Handling - Continuous W 600 Power Handling - Peak W 1200 Impedance Ohm 4+4 No Filter Component Subwoofers Voice Coil Ø 65 (2,5) Magnet size D x d x h mm (in.) 165 x 75 x 35 (6.5 x 2.95 x 1.38) Weight of one component kg (lb.) 8,63 (19.03) Magnet High density flux ferrite Cone Water-repellent pressed paper Xmech mm (in.) ±27 (1.06) D mm 260 Xmax mm 17 Re Ohm 1,9 Fs Hz 24 Le mH 1,6 Vas I 74 Mms g 235 Cms mm/N 0,19 BL T*m 12 Qts 0,42 Qes 0,45 Qms 5,9 Spl dB 86 A 321 mm 12.64 in.

Music fans who attend live concerts know well the emotions that low undistorted frequencies without dynamic compression can arouse. For this reason, the HertzAudioVideo R&D created ML 2500.3 Legend car audio subwoofer. During the long development phase, the designers set themselves just one ambitious goal: to transfer the emotions of a live performance to the car environment. Thanks to a completely renewed design, ML2500.3 car audio subwoofers have extremely compact size and are optimized to play in enclosures with reduced boxes. This choice of design combines two requirements hard to achieve up to now: reference performance and ease of installation.

ML 1800.3 Legend car audio woofers has been thought and designed for the enthusiasts attending contests who need a component merging the timbre accuracy of ML 1650.3 Legend to a wider extension to the low frequencies thanks to the large emission surface, higher power handling and control which only a 50 mm voice coil can ensure. To get to these results, the R&D staff performed extensive in-car voicing sessions, after building several prototypes with the FEA simulation method and testing them with a wide array of measurements carried out with the Klippel® suite. Like in the suspensions of competition cars, the surround must stand the most extreme working conditions to ensure maximum stability and symmetry at high excursions, and so to achieve impact and extension to the low frequency range. For this reason, the electro-acoustic designers developed a new surround-basket gluing system called “Boundary Free Surround”. This technology, provides the ability to achieve wider emission surface of the cone compared to speakers with same diameter; that way, the cone manages to move a bigger mass of air, so it produces more acoustic pressure.

During these past few years the Mille line car audio woofers have been the choice of many enthusiasts looking for extreme performance; with ML 1650.3 Legend the Hertz designers increased again the limits of achievable performance for components designed for door installation. To get to these results, the R&D staff performed extensive in-car voicing sessions, after building several prototypes with the FEA simulation method and testing them with a wide array of measurements carried out with the Klippel® suite. To ensure extraordinary power handling and very high thermal stability even with tracks especially rich of bass frequencies, ML 1650.3 Legend features a 36 mm mobile voice coil. This size ensures the best compromise between power handling and high frequency response.  The cone geometry has been subject of in-depth studies with FEA simulations and measurements performed with the Klippel Scan Vibrometer; all that led to the optimization of the V-cone® profile. In the subwoofers and in the woofers, to reproduce the lowest frequency spectrum, the cone needs to move a remarkable amount of air, so it is forced to make long excursions moving like a piston does. The V-cone® profile prevents the cone from deforming during its course, ensuring that the “piston” works in a correct position, maximizing the production of acoustic pressure.

Much time was invested in the research of the perfect material for the C 165 woofer cones: through a long process of customisation of the materials SPP-M was selected (Semi Pressed Paper-Mica), which preserves the natural sound of the semi-pressed paper and enhances it with Mica powder improving rigidity. The result is an excellent balance between lightness and damping, essential for a powerful and controlled emission. The oversized ferrite magnet provides excellent control even at higher excursions.

The SV 165.1 car audio midrange can be employed to build systems with tremendous impact. Like the SX subwoofers, the SV 165.1 features a solid, robust structure and, like all the other SPL Show components, it employs a copper voice coil wound on a two-layer KSV former, for unheard-of thermal and mechanical capability also in extreme circumstances. The cone features a water repellent pressed paper membrane and paper dust caps, both robust and light weight, as well as double-wave damped fabric surrounds to ensure linearity even under extreme conditions, contributing to high SPL scores.
