DrWho Posted February 20, 2006 Share Posted February 20, 2006 Who, With the PDF you posted you confirmed the Esotar is a very high power handling tweeter plus the Esotar is an elite tweeter. PWK said something along the lines of "bragging about power handling is like bragging that your car burns more gas" [] Nevertheless,150W continuous into a 92dB driver is nothing to write home about. Like I've said at the levels the Esotar starts to fail your ears will be long tired and you will be losing your hearing.So its a moot point,who listens at home at insane levels? NOBODY,any living being will suffer more than enjoy the sound past a certain SPL. And where most people will listen to music(even very LOUD)the Esotar is simply a top three tweeter world wide(the other two are the Accuton inverted diamond tweeter and the Scan Speak Revelator ). The tweeter just like any other direct radiator suffers early from amplitude compression, but surprisingly the pdf shows a very linear frequency response at different SPL's (despite the power compression)...you usually see a +6dB rise starting at about an octave above the Fs...and that's absolutely the last thing you wanna have in any driver. They must have done some fancy stuff with the suspension...you'll notice the system is mostly overdamped above 10kHz too countered by a few frequencies with extra resonance. I don't think it's possible to claim any single driver is the best in the world, or heck any single piece of equipment for that matter...there are simply too many other variables involved and I guarantee that in some way compromises were made. And there also has gotta be a horn loaded tweeter out there that sounds better too...and if it doesn't exist, then I'll just go build one myself just to make a point [] Quote Link to comment Share on other sites More sharing options...
Jay481985 Posted February 20, 2006 Share Posted February 20, 2006 build one and prove me and us wrong! I dare ya![] Quote Link to comment Share on other sites More sharing options...
TheEAR Posted February 21, 2006 Share Posted February 21, 2006 I dare you to build a better tweeter,a better sounding tweeter. The secret of the Esotar as you can see is its linearity with changing SPL. Yes you design a better one and and one that measures and sounds better and I will buy a pair. Until then,good luck.You will need it [] And while at it try building a better dome midrange than Dynaudio Esotar midrange. [] All in good spirit Quote Link to comment Share on other sites More sharing options...
DrWho Posted February 21, 2006 Share Posted February 21, 2006 Right, you're on...I'll even build it for 1/2 the price too. But you'll have to give me a few years of "R+D" [] Quote Link to comment Share on other sites More sharing options...
djk Posted February 21, 2006 Share Posted February 21, 2006 IEC is music power input to the crossover. Long term power of more than 20W will cause it to melt into slag. Virtually any good ferro-fluid dome tweeter will handle 1KW on HF tone bursts. Audio Magazine did such tests on a regular bassis. The PSB Stratus Gold had a Vifa dome and had no problems with 1KW tone-bursts. Dynaudio is OK, I bought quite a few when they were reasonable priced.

Duke Spinner Posted February 21, 2006 Share Posted February 21, 2006 . I call 1-800-PET-MEDS to get my medication! have you tried thier Flea Soap ..?? Quote Link to comment Share on other sites More sharing options...
TheEAR Posted February 21, 2006 Share Posted February 21, 2006 Duke, Flea Soap...yes ,I no longer have the nasty itch.Great product [] Who, So you needs hears of R&D just to best a little Dynaudio tweeter! Quote Link to comment Share on other sites More sharing options...
Jay481985 Posted February 21, 2006 Share Posted February 21, 2006 ok what exactly does ferrofluid do etc etc. Pictures and links as per appropriate Quote Link to comment Share on other sites More sharing options...
DrWho Posted February 21, 2006 Share Posted February 21, 2006 So you needs hears of R&D just to best a little Dynaudio tweeter! No, it'll just be a few years before I have enough money to begin building drivers on my own. It costs like $10k just to get the molds made...startup costs are insane. I would just call it "R&D" because I'm bound to be learning more in the meantime (so the better tweeter I'd build now probably wouldn't be as good as the one I'd build later). Building better isn't that hard...but building better AND cheaper is. Quote Link to comment Share on other sites More sharing options...
DrWho Posted February 21, 2006 Share Posted February 21, 2006 ok what exactly does ferrofluid do etc etc. Pictures and links as per appropriate Think of it as water cooling for a tweeter...the "ferro" part of the word refers to the fact that the fluid conducts magnetism - thus keeping the fluid in the gap between the magnet and the pole piece. Or at least that's what I've been led to believe...I wouldn't consider myself a qualified source. You tried googling it? Quote Link to comment Share on other sites More sharing options...

[] Yes the ferrofluid is there to help transfer the heat while not restricting the magnetic field. Most cheapo tweeters that are "ferrofluid" cooled as they say probably use Crisco oil.

DrWho Posted February 22, 2006 Share Posted February 22, 2006 you wanted a website: http://www.ferrotec.com/usa/ferrofluid_technology_overview.htm And here's a pic: (from http://www.miragespeakers.com/spk_fund.shtml) Btw, just a minor correction...I meant to say the ferrofluid sat inside the VC (ie, between the VC and the pole piece). When replacing the diaphgragm on a tweeter you wanna be careful not to spill it everywhere [] Quote Link to comment Share on other sites More sharing options...
Jay481985 Posted February 22, 2006 Share Posted February 22, 2006 that is sorta boring... since it will overheat if the ferrofluid is heated to max thermal capacity Quote Link to comment Share on other sites More sharing options...
DrWho Posted February 23, 2006 Share Posted February 23, 2006 lol, you expect tweeter voice coils to exceed 300F? I believe 1000W into a subwoofer is generally running around 500F... Quote Link to comment Share on other sites More sharing options...
