Has anyone or any company ever considered using a metallic spider to reduce mechanical losses, and create high qms drivers?
Although this may only really be applicable to high suspension stiffness low Xmax drivers, would it be possible to use a metallic flexure in place of a regular spider, to avoid viscoelastic losses associated with polymer based solutions? As metals have very very low tan delta coefficients (viscoelastic loss). I'm not completely sure if it would be of much benefit other than allowing lower Qes values for the same Qts but its likely marginal.

Probably, but I was thinking hypothetically of shifting the mechanical losses to the cone surround to minimise cone edge resonance more without an increase In Rms of the whole system. Other materials could be substituted that have higher tan deltas around the resonant peaks but would only really be effecting above the usage frequency band, e.g carbon fiber composite in place of metal.
