Cheers George please tell me more. what freq range does it do? is it omnidirectional? does it glow very bright at night or just small purple flame? Cheers!
georgehifi Posted April 26, 2013 Posted April 26, 2013 4.5khz to 150khz or higher, 95db at mid level control setting, omnidirectional, purplely flame about 1/3 the brightness amount of a small kids birthday candle. It is the best highs you will ever hear, as it uses the air around the flame as the diaphragm, the lightest possible thing that can be used, the highs just float in the room. Cheers George
tuyen Posted April 26, 2013 Posted April 26, 2013 cheers for info! I would like to hear these highs floating in my room. were you thinking of selling? (currently not in position for any more hifi purchases, but thought I'd ask anyway) HEHE

No, I think I have this right, I believe they ionize the air around the tip of the Tungsten rod at high voltage, which creates maybe a gas and is gas is then modulated to the music, the only thing that needs replacing after years of use is the Tungsten rod as it gets shorter, and replacements are easy, as all you do is go to an engineering shop for the Tungsten rods and get then cut to length which are about 4" long, 1 for each tweeter. Cheers George

From my reading the only problems with some of these is the constant hiss of the gas. Usually helium. No gas, no problems! Linc
georgehifi Posted April 26, 2013 Posted April 26, 2013 (edited) That vid Nada posted is not like these, they are perfectly quite no hiss, as for gas, they say if you are in a very small room with them on, you should leave a door or a window open a little, otherwise you will detect a slight ozone smell they were fine in my reasonably large room all day.

They look as if they are so beautifully crafted rather than mass produced. Small world, or 6 degrees of separation!: in the video, he says those speakers were originally commissioned by Anton Corbijn. One of my big sisters used to go out with Anton. We had lunch a few years ago in Melbourne when we was here to promote his film about Joy Division. He's a lovely, modest guy! I recall we discussed Captain Beefheart, whom Anton knew personally (I later found out he made a documentary about him). - r.

peterstt Posted April 26, 2013 Posted April 26, 2013 If someone can bring the ionizer response down to 16Hz.....woo..... Must be the closer to the original sound....
tuyen Posted April 26, 2013 Posted April 26, 2013 Hahaha very cool rab! Love Bryan's work hope to hear his system one day! No plasma tweeters for me. More than happy with me Goto tweets. I not sure if I'm that big of a fan for omnidirectional drivers tbh! Peter, plasma driver that can do 16hz? A flame that is meters long? It would kill us both! Haha
tuyen Posted April 27, 2013 Posted April 27, 2013 (edited) test run as simple 2-way with the rythmik active powered direct servo sub to fill in the lows. bass horn just playing full range (seat cushion placed in throat at the folded section of horn used as a physical attenuator for the high freqs) and beyma tpl-150h amt driver wired in with a 8.25uf cap. tis actually quite nice and balanced! effortless! update: added the mid low horn back into the system Edited April 28, 2013 by tuyen 2
Owen Y Posted April 27, 2013 Posted April 27, 2013 tuyen, I was thinking earlier... if your midrange is running wide open without xover, then the Beyma HF may not be sensitive enough at ~95dB/W...? I am still looking for an affordable tweet that is 105dB.
tuyen Posted April 27, 2013 Posted April 27, 2013 Hi Owen, I thought it was ~102db/W when horn loaded? http://profesional.beyma.com/ingles/pdf/TPL150H.pdf But yeah, I think only cd tweets will have the efficiency you are after.. or just compromise and use l-pad to find out how much attenuation needed, then replace l-pad with pair of decent resistors.. that's how I padded down the most sensitive channel which was the goto mid-low paired with the 200hz horn.
Owen Y Posted April 28, 2013 Posted April 28, 2013 Ah yes I see... I'm using Fostex T90A, but HF rolloff is evident & I may have to accept padding down midrange horn to match T90A. Or, implement another HF setup. I will have to do some measurements soon.
tuyen Posted April 29, 2013 Posted April 29, 2013 5-way back up and running. active sub doing 60Hz and under, bass horns only doing 60-400hz, goto midlow 400-3kHz, beyma 3-7kHz and goto tweeter doing 7kHz onwards. good! hrmm should really invest in a nice rack. lol! 2
Upfront Posted April 29, 2013 Posted April 29, 2013 Looking good mate! Gear on the floor is cool... If your going for the nutty audiophile look!!! Is that the minidsp measuring thingy you've got set up there with the mic?
