20_Reference in design: power and<br />

harmony in a mix of sharp lines and<br />

widely curved profiles.<br />

The anti-resonant aluminium alloy<br />

basket features five low incidence<br />

spokes and offers the minimum<br />

back radiation resistance, eliminating<br />

every distortion due to acoustic<br />

compression.<br />

The self-standing geometry of the<br />

structure contributes to total<br />

mechanical damping, performing a<br />

perfectly transparent sound.<br />

21_Basic design and care for details.<br />

The gasket is designed to allow<br />

both possible mountings.<br />

In the traditional position a rubber<br />

gasket ensures a perfect hermetical<br />

seal and the inserts, imitating the<br />

spokes lines, protect and cover the<br />

subwoofer fixing screws.<br />

When the sub is used with the<br />

magnet visible, the gasket<br />

can be mounted upside down in<br />

order to finish off the basket nicely.<br />

with high thermal and mechanical<br />

linearity.<br />

Like competition cars suspensions,<br />

these elements must stand the<br />

most extreme conditions:<br />

ensuring the utmost stability and<br />

symmetry at the highest<br />

excursions for astonishing impact<br />

and amazing extension to the<br />

low range.<br />

23_ The dual layer mobile voice coil with<br />

copper covered aluminium wire<br />

(CCAW), the subwoofer throbbing<br />

heart, is wound round a carbon<br />

fiber support, stiff and light to<br />

ensure very high mechanical Qs,<br />

transferring the energy to the cone<br />

with amazing efficiency.<br />
