I hadn’t come across this myself - great story, thanks Steve!
Nelson Pass’ ‘perfect’ mass-less, full-range Ion Cloud speaker, 1980.
Notice: HIGH VOLTAGE Nix fingerpoken
Nelson describes ‘The Ultimate Audiophile Product’
It’s:
- Exotic
- Incredibly expensive
- Horribly inefficient
- Unavailable, and
- Toxic
All pretty cool in my book.
