Yeah, I remember those crazy Hills. I think that there also might have been dangerously high voltages on exposed elements of the plazma drivers...this was the reason that the F.T.C. banned these speakers (but maybe that was just the rumor mill B.S.) But I think that these speakers used Nitrogen not Argon to create the plasma. Happy Tunes!
Plasma speakers anyone with info?
I can find many sites for diy but cannot find any for sale . Help! Nick
