Audax, the maker of the driver, actually supplies Aerogel drivers to other companies, one of them being Pinnacle.
I found this statement on the web via a Google saerch about Audax's Aerogel technology:
"Audax's aerogel material, for which the company holds a number of patents, uses carbon-fibres to impart stiffness to the cone, to prevent break-up and ensure the cone acts like a piston over its entire operating range. However, to prevent the resonances that can occur in carbon-fibre designs, Audax also incorporates a gel-like material, to provide a measure of damping. Both are applied over a paper base."
