The Sound Experience

1_Tetolon ® Fiber dome with hemispherichyperbolic 

profile. The 28 mm 

diameter, the dome height and the 

special profile ensure maximum 

stiffness and the right linearity for flat, 

smooth frequency response even 

beyond the audible range. 

2_The motor assembly special shape 

creates perfect field symmetry which 

provides startling energy. Thanks to the 

use of a double REN ® Neodymium 

magnet, ML 280 can maintain mobile 

voice coil movement linearity even at 

extreme excursions, ensuring 

extraordinary energy for state-of-the-art 

performance. 

3_The upper pole, covered by a pure 

copper short circuit ring, generates an 

anti-inductive effect, flattening impedance. 

CCAW copper covered aluminium 

wire voice coil makes this mobile 

voice coil very light, yet stiff. These 

elements act together, providing 

the best SPL values and the best 

response at very high frequencies.

4_Cooling and decompression radial ducts. 

Designed in order to enhance heat 

dissipation and to avoid compression 

under the dome, they optimise mobile 

voice coil damping and resonance. The 

holes special geometry and the rear 

resonance chamber provide natural, 

linear sound by eliminating all noise. 

3

5_ Acoustic chambers with different 

loading. The tweeter can be used in 

different configurations, since it is 

possible to choose the best Q for the 

system by changing the rear acoustic 

chamber. The chambers simulate 

sealed box configuration; they are 

filled with natural, non-woven absorbing 

material for the component best 

damping. The small chamber increases 

Q factor and makes the tweeter slope 

sharper; the big one makes slope 

smoother at lower frequencies. 

6_ Die-cast aluminium alloy face plate. 

Stiffness, damping and lightness, 

reflections analysis and sound 

accuracy for a component which 

surpasses any other references. 

7_ Ultra-light Mylar membrane, 117x15 mm, 

with silver deposit. The special 

treatment with valuable metal gives 

Mylar the right tiffness; thanks to it, 

to the material lightness and to the 

magnet special structure, frequency 

response can go from 70 to 35000 Hz. 

8_ Dipolar emission. Acoustic radiation is 

not affected by a back load; this way 

the membrane works in maximum 

symmetry, with ideal damping, 

5 

ensuring the most natural, 

colorless musical reproduction. 

9_ Paper cone with cotton fibers 

molded with water-repellent 

impregnating materials. The 

exponential profile without dust 

cover gets very close to the ideal 

one, providing exceptional 

dispersion. The use of a paper 

support optimises mechanical 

coupling, eliminating break-up 

phenomena and ensuring the 

smoothest high frequency response.

10_Rubber, latex and silicone doublewave 

surround, with sinusoidal profile. 

This evolution of the innovative DWR ® , 

with integrated gasket, can stand 

extreme linear excursions, setting a 

new standard in musical 

reproduction. 

11_ Anti-resonant aluminium alloy basket. 

The special low incidence basket arms 

provide membrane with minimum 

back radiation resistance and eliminate 

distortion. The self-standing structure 

helps in mechanical damping without 

affecting acoustics. 

12_The ferrite magnet assembly was 

designed using state-of-the-art 

development softwares and generates 

a very high field power. Its considerable 

size does not hinder the mounting but 

is the main feature to grant a very 

high thermal stability and bursting 

dynamics. 

13_Aluminium die-cast central case. 

Utmost care and attention are paid 

to every detail: the filter case, 

with hidden fixing system, is made 

of inert material, to reject all 

vibrations.

14_Aluminium die-cast central case. 

Utmost care and attention are paid 

to every detail: the filter case, with 

hidden fixing system, is made of 

inert material, to reject all 

vibrations.

15_TAD ® + HFC ® : time alignment and 

listening point optimisation system. 

The car compartment has fixed 

listening positions and the 

components forced installation 

sometimes places them at different 

distance and non favourable 

angulations. Thanks to these 

adjustments, both the driver and 

the passenger will be able to fully 

enjoy the components best acoustic 

response, simply by setting the 

right adjustment on the filter. 

16_Filters are pre-set in order to allow 

multi-amplification connections. 

The possibility to set an endless 

number of configurations makes 

these crossovers extremely flexible 

and universal. 

17_Inductors: 1mm Quadralitz copper 

coils, low resistance, high saturation 

flux; Capacitors: polyester film, 100 

Vdc, very low DF; Layout: 1.7 mm 

shockproof FR2 with very thick pads. 

18_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 

15 

TAD/HFC on 

TAD/HFC off 

break-ups to provide the maximum 

undistorted performance. 

19_Power transfer is carried out through 

screw terminals that accept peeled 

cables up to 5 AWG. The terminal 

blocks are inside the mounting 

surface and are arranged to allow 

the linear connection of the cable. 

Mounting on elastic support 

preserves the mechanical integrity, 

protecting the nerve center of the 

component from the vibrations that 

the sub can generate. 

16 17 

18 

19

20_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. 

21_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. 

22_Foam surround and Conex ® spider 

with high thermal and mechanical 

linearity. 

Like competition cars suspensions, 

these elements must stand the 


20 

Technology 

most extreme conditions: 

ensuring the utmost stability and 

symmetry at the highest 

excursions for astonishing impact 

and amazing extension to the 

low range. 

23_ The dual layer mobile voice coil with 

copper covered aluminium wire 

(CCAW), the subwoofer throbbing 

heart, is wound round a carbon 

fiber support, stiff and light to 

ensure very high mechanical Qs, 

transferring the energy to the cone 

with amazing efficiency. 

22 

21

The support is set on the cone 

bottom through a self-referring 

system, for a mechanically perfect 

mounting. 

24_ The spider support contributes to 

total mechanical performance. Made 

to improve the dispersion of the heat 

generated by the coil and to reduce 

the compression below the spider, 

it favors the thermal exchange with 

the outside increasing the power 

performance. 

25_ 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. 

26_ High current lead wire integrated 

in the spider. The conductors which 

transfer the current to the voice coil 

are not subject to mechanical 

23 24 

stress; so they generate electrical 

and mechanical safety, and 

furthermore grant a silent operation 

even at the highest excursions. 

27_ Like in motorbikes chassis, the 

anti-resonant aluminium carter 

covering the magnet closes the 

basket in a unique configuration, 

performing aesthetical and 

mechanical functions. The stiffer 

structure contributes to eliminate 

the resonances induced in the 

subwoofer bearing system.

1_Cylindrical Dust Cover ® 

Cylindrical paper dust cover. Its 

geometric structure doesn't create any 

breaks in the cone. The cylinder nondeformability 

stiffens the most delicate 

part of the cone and insures excellent 

acoustic results. 

2_Hyperbolic Paper Cone ® 

High pressure molded, water-repellent 

paper cone. Its special hyperbolic 

profile and its being fixed onto the 

surround stiffen the emitting device 

increase the radiating surface and 

flatten high frequency response. 

3_Double Wave Rubber Surround ® 

Surround and integrated gasket are 

made of rubber, latex and silicone. 

The longest excursion which the 

double wave insures makes mobile 

voice coil movement more linear, 

eliminating dangerous mechanical 

distortions. 

4_Polycotton ® 

Acrylic and cotton spider with calibrated 

height. It mechanically controls musical 

signal reproduction without affecting 

it. The rationality, functionality and 

efficiency of materials insure long-term 

reliability and performances.

5_ Symmetrical Field Engine ® 

The motor assembly special shape 


provides startling energy. Its small 

dimensions conceal the system 

total capacity, which can keep 

mobile voice coil movement 

linear even at the longest 

excursions.

6_Polymer Basket ® 

Anti-vibration composite polymers 

basket. Polycarbonate and fiber-glass 

make it very light, yet stiff, decreasing 

resonance increasing damping factor. 

7_Radial Cooling Ducts ® 

Radial holes system. The forced 

ventilation circuit keeps voice coil at 

constant temperature, dissipating 

heat, and improves thermal capacity 

and power handling. 

8_Back Aluminium Heat Sink ® 

Anodised aluminium heat sink. The 

magnet is fixed onto a support which 

is turned through high precision 

process and which transfers heat 

from the magnet bottom pole 

outwards. This system favours the 

flux of the heat generated by the 

watts dissipated during musical 

reproduction, increasing maximum 

real power. 

9_Black Aluminium Former ® 

50 mm mobile voice coil, wound on 

two layers inside a Black Aluminium 

Former ® with outstanding thermal 

and mechanical capacity. Windings 

precision and glues quality insure 

power handling, control and energy.

10_CCAW Duraluminium Voicecoil ® 

CCAW copper covered aluminium wire 

mobile voice coil, wound on two layers 

on a Duraluminium former. The use of 

special materials makes this mobile 

voice coil particularly light and stiff, 

insuring unparalleled SPL values 

and high frequency response. 

11_Tetolon Fiber ® 

28 mm semispheric dome. Natural 

fiber is combined with a closed fiber 

with double waterproof coating and 

makes tweeter sound crisp yet soft. 

Outstanding frequency response, 

off-axis response and linearity are 

insured in whatever conditions. 

12_Symmetrical Field Engine ® 

The motor assembly special shape 


provides startling energy. Its small 

dimensions conceal the system total 

capacity, which can keep mobile voice 

coil movement linear even at the 

longest excursions. 

Rare Earth Neodymium ® 

High thermal threshold neodymium. 

The powerful, exclusive magnet 

permeability is 100 times higher than 

the one of ordinary, equally big ferrites.

more efficient than a traditional tweeter 

and it can provide extraordinary 

energy for superb performances. 

Copper Ring Pole ® 

Pure copper short circuit ring. The 

upper pole outside the voice coil 

generates an anti-inductive effect. 

By flattening impedance, it allows 

the tweeter to reach higher frequencies, 

providing even, excellent trebles response. 

13_Back Sealed Box ® 

Acoustic chambers with different 

loading. The tweeter can be used in 

different configurations since it is 

possible to choose the best Q for 

one's system by changing the rear 

13 

acoustic chamber. The chambers 

simulate sealed box configuration; 

they are filled with natural, non-woven 

absorbing material for the component 

SFE ® REN ® CRP ® 

BSB ® 

best damping. The small chamber 

increases Q factor and makes the tweeter 

slope sharper; the big one makes slope 

smoother at lower frequencies.

14_Attenuation System ® 

Filters have tweeter sensitivity control. 

Thanks to the 2dB-step attenuators, 

the speaker can be perfectly adjusted 

in any cars and according to any 

needs. 

15_Best Sound Control ® 

Listening point optimisation system. 

The car compartment has fixed 

listening positions and the 

components forced installation 

sometimes places them at non 

favourable angulations. 

Thanks to BSC ® , it is possible to 

adjust the speakers emission in 

order to make up for woofer and 

tweeter natural loss at high 

frequencies. 

Thus, the driver or the passenger 

will be able to fully enjoy the 

components best acoustic response 

simply by setting the right 

adjustment on the filter. 

16_Components 

Resistors: metaloxide, high power 

and precision, non inductive; 

Inductors: 1 mm copper coil, low 

resistance, high saturation flux; 

Capacitors: polyester film, 100 Vdc, 

very low DF; Layout: 1.7 mm 

14 

AS ® BSC ® 

shockproof FR2 with very thick 

pads. 

16_Triple Resistor Heat Sink ® 

Aluminium heat sink for 

resistors. Metaloxide resistors 

are assembled on a special 

heat sink which improves their 

performances and power 

handling. Heat dissipation 

and the consequent stabilisation 

of the resistors working 

temperature avoid dangerous 

value and temperature 

variations, optimising acoustic 

results.
