The PVD (physical vapor deposition) Lab is equipped with advanced machinery capable of depositing a layer of diamond on the membranes of Raidho's drivers. Obviously, this kind of science and the equipment needed to execute is well beyond the means of hi-fi companies, save in Denmark, where the government and the universities work in concert with small manufacturing firms.

Of course, this science doesn't come for free. Companies like Raidho have to pay a sizable fee for the use of the PVD Lab. Nonetheless, the fact that a small company can access such a facility (and the Ramp;D of the Tribology Centre) is amazing.
