C-W were also showing a 12-inch(?) driver which they would
plug directly into the 120V power mains outlet in the hotel room.

Julian Hirsch tested it for stereo review, "the only result was a very loud
noise, no harm to the speaker"

There were rumors that C-W cracked some plaster and had to
pay the hotel for repairs. And other rumors that the JBL demos
in another room down the hall, were reproducing such realistic
gunshot sounds (thanks to their 075 ring radiator tweeters, aka.
the "acoustic laser") that the LAPD was called out to investigate.
