[. . . ] The voice coil itself is constructed of edge-wound rectangular aluminum wire, mounted on a rugged, laminated polyimide former. The complete assembly is low in mass and is fabricated using the most advanced epoxies, insulations and materials available. Great care was taken in the selection of diaphragm materials and construction to ensure smooth, musical upper-bass reproduction and accurate low-frequency shock capability (punch). The cone has a moisture-repellent treatment, allowing it to be used in harsh and humid conditions.

Xmax is the one-way peak excursion which produces 10% THD of the current waveform when driven at fs. Displacement limit is the one-way peak excursion which, when exceeded, will cause physical damage to the drive mechanism.
