The support is set on the cone<br />
bottom through a self-referring<br />
system, for a mechanically perfect<br />
mounting.<br />
24_ The spider support contributes to<br />
total mechanical performance. Made<br />
to improve the dispersion of the heat<br />
generated by the coil and to reduce<br />
the compression below the spider,<br />
it favors the thermal exchange with<br />
the outside increasing the power<br />
performance.<br />
25_ The combination of flared port with<br />
radial holes in the central pole in the<br />
bottom plate carries the air compressed<br />
by the cone movement directly to the<br />
mobile voice coil and outside the magnet<br />
assembly, producing a 30% fall of the<br />
speaker operation temperature. The<br />
improvement of the air flows inside<br />
the motor, with this peculiar channel<br />
geometry, creates a forced ventilation<br />
circuit that drastically reduces the<br />
dynamic compression, raising the<br />
applicable power over the top.<br />
26_ High current lead wire integrated<br />
in the spider. The conductors which<br />
transfer the current to the voice coil<br />
are not subject to mechanical<br />
23 24<br />
stress; so they generate electrical<br />
and mechanical safety, and<br />
furthermore grant a silent operation<br />
even at the highest excursions.<br />
27_ Like in motorbikes chassis, the<br />
anti-resonant aluminium carter<br />
covering the magnet closes the<br />
basket in a unique configuration,<br />
performing aesthetical and<br />
mechanical functions. The stiffer<br />
structure contributes to eliminate<br />
the resonances induced in the<br />
subwoofer bearing system.<br />
