Simply said.
A piston (cone) speaker is nothing more than a AIR PUMP.
A given material has nothing to do with it's sonic signature.( Woody) or Steely. But has everything to do with the speed & ease in which it responds to the electrical signal variances from the AMP. Sure materials vary from Mfg to Mfg only because they are sure that cone made from there proprietary Nirvana X material.IS ABSOLUTE!!
Clarity hopefully,
