Warning

• The symbol on the right shows that it is advisable to carefully 
follow the highlighted instructions. Failure to respect these 
instructions may cause unintentional harm or damage 
to the components. 
• Before installing the components, please carefully read all of the instructions contained 
in this manual.
• In order to simplify the installation, prepare a detailed plan of your installation configuration 
and connect the cables safely and neatly.
• Always wear protective eyewear when using tools.
• In order to avoid possible damage, store the product in its package during installation 
construction.
• All of the structures built to house the different components must be firmly and reliably attached 
to the vehicle chassis using brackets, screws, nuts and bolts, in order to ensure a solid and safe 
installation.
• If the component comes loose from the vehicle chassis while driving, this may cause serious 
damage to the vehicle and injury to passengers in the car. Attach the components properly, with 
the utmost care, especially in the case of installation inside the vehicles interior. 
• Do not carry out any installation inside the engine compartment. 
• Before you start the installation, turn off the head unit and all the electronic devices of the audio 
system in order to avoid any damage and disconnect the negative battery terminal.
• Make sure that the location you chose for the components does not hinder the correct 
functioning of any mechanical or electric device in the vehicle.
• Do not put cables or install the components close to electronic or mechanical devices.
• Be very careful when you drill or cut into the vehicle chassis, and make sure that no cables 
or structural elements essential to the car are underneath or in the selected area.
• The connecting cable must have an insulation which is mechanically resistant and 
self-extinguishing in the case of fire. The cable section must have the size indicated herein. 
When you route the cable, do not press the cable against sharp edges or near a moving 
mechanical device. Make sure that it is firmly attached and protected for its entire length.
• Protect the conductor with a rubber ring (grommet) if it passes through a hole in the vehicle 
chassis or with proper protection materials if it runs close to heat-generating parts.
• Do not pass the wires outside the vehicle; this is not reliable or safe.
• When you install the components and their connecting cables, make sure that they do not touch, 
even occasionally, any part of the cars chassis. In this case the amplifier protection triggers.
• In order to avoid any problems, use top quality cables, connectors and accessories choosing 
them in the CONNECTION Audison catalogue.
• Once your installation has been completed, check the system wiring again for proper connection 
before turning the system on.

Tecnology

The 

MILLE

 line has revolutionized the market since its introduction in 1999; 

designed to be the new reference and meet the needs of the most 
demanding enthusiasts, providing reference performance.
These components have set a new standard in sound reproduction, 
winning people’s appreciation and prestigious awards by the specialized 
press. Constant innovation and product development have always 
been the foundation of Elettromedia’s research program for 

HERTZ

Today the R&D team has succeeded in improving what seemed to be 
already perfect.
The new ML Subs set a new benchmark for low frequency 
reproduction. The lowest octaves of the audio range are delivered 
with the powerful impact, dynamics and control that only a reference component can achieve. 
These speakers represent the pinnacle of technology, in all parts of the subwoofer construction.
The V-CONE™ profile is applied to a Polypropylene cone stiffened with mineral 
dusts; eliminating any break-up, offering the best undistorted performance.
To stand the most extreme conditions, the surround has been designed like a 
racing cars’, ensuring the maximum symmetry at very high excursions.
The center pole piece, with a turned aluminum ring inside the motor significantly 
reduces distortion due to field asymmetry and reduces inductance modulation at high excursions; 
for a harder, deeper and more accurate bass.
The throbbing heart of the subwoofer; the dual layer, high temperature copper voice coil, is wound 
on a very high Q fiberglass former to transfer energy to the cone in a highly efficient manner.
Using special channels, significant improvements have been made to the air flow inside the motor 
itself. This proprietary design creates a forced ventilation circuit that significantly reduces dynamic 
compression, raising power handling over the top.
The proper current transfer depends on the wire terminals; in this case, accepting cables up to 
5 AWG for huge current transfer, ergonomically arranged to add to the speakers lines.
The ML subwoofers set a new landmark in cosmetic design. Power and harmony in a mix of sharp 
lines and widely bent outlines. The basket is made from anti-resonant aluminum alloy and features 
a five spoke design, adorned with an insert that creates a contrast between materials and colors, 
reminding one of a backbone covered in stretched muscles. This self-standing structure 
contributes to the overall mechanical damping for incredibly transparent sound.
Basic design and attention to detail can also be found in the gasket, designed to mount 
the component in two possible ways: both in the traditional “cone out” position 
as well as inverted, where the sub is mounted with the frame/magnet 
structure in sight. The trim ring has the same design as the spokes, 
protecting and concealing the fasteners used to fix the subwoofer. 
The same holes are used to accommodate the fixing of the optional protection 
grille, which then becomes an integral part of the speaker.
The structure covering the motor assembly completes the design and protects the same, 
combining the aesthetic value and the technical importance of the overall system.
Passion drives us to design the ultimate products; where the only basic requirement is quality 
without compromise.
Dedicated to sound: for a unique, exciting experience.
