I must inform You all about a new kind of loudspeaker, invented in
China. It consists of a very thin Nano tube film, much thinner than the one
in Esl:s. No transformer is needed, purely resistive load. However, a bias voltage must be applied to prevent frequency doubling, just as in Esl:s.
It has no problem reaching one megahertz treble! Sensitivity is higher than that of dynamic speaker and is, according to the article, very easy to manufacture.
