I am all for supporting new and unusual ideas... but I don't see any sense in supporting ideas that go against well known physics such as increasing mass to lower the resonant frequency and the implications this has on a loudspeaker design.

So I support new ideas and inventions but NO I don't support people who are clearly just trying to rip the public off.

As for cables I think the question is, do different cables that are ALL capable of adequately handling the signal make an audible difference? Bell wire doesn't take 100watts at low voltage very well.
