Nope.  It was real.  The system could use environmental air but 
would generate ozone as a result.  In the Audio magazine article, the
inventor would get asthma attacks near any electrostatic device
(I.E. photocopiers) after demonstrating it for the CES convention.

It did sound great but needed subwoofers (conventional) to make
up the low-end.

If I ever run across the article again...
