Powerful from the lowest octaves of the audio range. The Hertz ML subs set a new benchmark for low frequency reproduction with the impact, dynamics and pressure that only a reference component can achieve. Power and harmony in the anti-resonant aluminium alloy basket design, self-standing low incidence five-spokes structure, Front-Back Gasket, magnet protection. Ultimate technology in every detail: V-cone with Polypropylene membrane stiffened with mineral dusts, high excursion surrounds, extended pole piece, dual layer mobile voice coil with copper covered aluminium wire (CCAW), oversize motor assembly with an exclusive forced ventilation circuit. A harder, deeper and more
controlled bass for a unique enthralling experience.

The V-cone is applied to a Polypropylene membrane stiffened with mineral dusts. The exponential profile without dust cover gets very close to the ideal one and eliminates break-ups to provide the maximum undistorted performance.

Reference in design: power and harmony in a mix of sharp lines and widely curved profiles. The anti-resonant aluminium alloy basket features five low incidence spokes and  offers the minimum back radiation resistance, eliminating every distortion due to acoustic compression. The self-standing geometry of the structure contributes to total mechanical damping, performing a perfectly transparent sound.

The combination of flared port with radial holes in the central pole in the bottom plate carries the air compressed by the cone movement directly to the mobile voice coil and outside the magnet assembly, producing a 30% fall of the speaker operation temperature. The improvement of the air flows inside the motor, with this peculiar channel geometry, creates a forced ventilation circuit that drastically reduces the dynamic compression, raising the applicable power over the top.

The “Symmetrical Shape” central pole addresses the external lines increasing the magnetic flux density and perceptibly decreasing the field asymmetry distortion. An aluminium rounded ring inside the motor cuts the inductance modulation at the highest excursions, for a harder, deeper, clearer bass.

Basic design and care for details. The gasket is designed to allow both possible mountings. In the traditional position a rubber gasket ensures a perfect hermetical seal and the inserts, imitating the spokes lines, protect and cover the subwoofer fixing screws. When the sub is used with the magnet visible, the gasket can be mounted upside down in order to finish off the basket nicely.
