jtkinney Posted January 8, 2008 Share Posted January 8, 2008 I ran across this article looking for something else. While not very practical, it would give you bragging riights to the hottest horn speakers. Enjoy. Thermal-horn.pdf Quote Link to comment Share on other sites More sharing options...
Arkytype Posted January 8, 2008 Share Posted January 8, 2008 Jim, Yeah, next thing you know it'll be "Which sounds better, butane, propane or natural gas?" Then the esoteric audio dealers will be selling refillable cylinders of bovine methane touting their gas as the only one able to create organic eargasms. Where's my No BS button?

jtkinney Posted January 15, 2008 Author Share Posted January 15, 2008 Arkytype, I bet the author never thought of custom gasses. Sounds like a thesis topic for someone. Billybob, Oxy Acetylene may be a little too much amplification. Quote Link to comment Share on other sites More sharing options...
IndyKlipschFan Posted January 15, 2008 Share Posted January 15, 2008 Somewhere as a kid I am sure I heard a tweeter that was like a flame of some sort. Wish I could remember it was very very "airy" sounding if I remember right, and did not have any directional cue as to where it was driven too? Anyone remember this?

billybob Posted January 15, 2008 Share Posted January 15, 2008 Billybob, Oxy Acetylene may be a little too much amplification. Glad you said that. Just recalled this Home-Brew party in the city of Tally, awhile back. Event had all of these antique/collectable tapheads, all in a row to sample the different tastes. Anyhow, someone there had these line leads oxy-acetylene combined with a electric trigger filling up these plasic bottles and then this super- loud BAM!!! Like a call-a-cop dinnerbell!

DrWho Posted January 15, 2008 Share Posted January 15, 2008 Hmmm...I have a feeling that these run a bit hotter... (click for larger image) And then here's a video of them playing music (since a photo simply doesn't capture the effect): Quote Link to comment Share on other sites More sharing options...
jtkinney Posted January 15, 2008 Author Share Posted January 15, 2008 IndyKlipschFan, I seem to remember some plasma speakers. Used a bottle of helium and a very high voltage to create the plasma. Never saw any, just read about them. Quote Link to comment Share on other sites More sharing options...
jtkinney Posted January 15, 2008 Author Share Posted January 15, 2008 DrWho, As a kid we had a Jacob's Ladder (think Frankenstein movies) made from a neon light transformer and a couple of welding rods sitting in the corner of our bedroom that looked a little like your photo, just smaller. No safety features between us and 17,000 v. I can't see me trying that with my kids without breaking several laws. Quote Link to comment Share on other sites More sharing options...
michael hurd Posted January 15, 2008 Share Posted January 15, 2008 I have an old book with a picture and a company with the helium plasma tweeters in it somewhere.... I should find it. Quote Link to comment Share on other sites More sharing options...
jtkinney Posted January 16, 2008 Author Share Posted January 16, 2008 Billybob, We used to do that as kids, except we used balloons and pieces of paper to ignite them. Dad used to wonder why his welding tanks were low. A friend thought that balloons were too small and tried a garbage bag. Unfortunately for him, the static electricity from the bag opening as it filled, lit the gas and removed most of his hair. It did grow back much later.

stereohermit Posted January 17, 2008 Share Posted January 17, 2008 the HILL PLASMATRONICS was a high-end speaker from the late 70's.Three way sys ...12" woofer, 5 or 6" mid, plasma tweeter. Heard a few times, great from 4-5k up. Bas was mediocre, mid so-so. But the upper mid top was wonderful. In fact, the tweeter was so fast, it made the other drivers sound slow, leading the system to poor top to bottom coherency. They sold for 7,000 dollars at the time.
