W15CH001E0037

Precision cast and surface treated magnesium cone coupled to a natural rubber
surround showing no sign of midrange (edge) resonances.

Patented Hexadym magnet system of acoustically transparent design to avoid
cavity resonances and air fl ow noise. The magnet system based on 6 small, radially
magnetized Neodymium blocks is compact to reduce the refl exion of sound energy
to a minimum.

Heavy copper rings mounted above and below the T-shaped pole piece reduce non
linear and modulation distortion and increase overload margin.
Extremely stiff and stable injection moulded metal basket keeps the critical
components in perfect alignment. Large windows in the basket both above and
below the spider reduce sound refl exion, air fl ow noise and cavity resonance to a
minimum.

A solid copper phase plug enhances the performance of the copper rings and
improves heat conduction away from the pole piece.
