Rubbish! A friend of mine had a pair and the
Hi,
here in Aalto university there has been quite a lot of research using lasers to
generate precise omnidirectional impulses at various focusing points for
impulse response measurements of enclosures.
I also remember during a lecture in ISVR, UK, the lecturer mentioning these old
plasma tweet
Are these not the same as the Ionophone speakers,
sold as Ionofane tweeters in the 1960s? They were flat from 10kHz to oo!
