Post Subject: Civilised sound of a tweeterPosted by Wojtek on: 3/2/2011

I have to admit I have no idea and did not experiment with matching horn loaded tweeter to big ,direct radiating "extended range' MF channel. I'm not sure it's doable. I was speculating on the reasons why the owner of Moscow instalation switched from GOTO to fostex tweeter. Horn laded 8" is a different thing than the same driver used as a Direct Radiating unit and although I agree that while the sonic signature of MF /HF should be the same good luck finding appriopriate tweeter. My impression on fostex's sound came from substituting 500MKII with Tad ET-703 (custom leCleach horn instead of TAD's slot) in friends instalation. MF driver was 2" modern JBL neodymiun unit (I don't remember the type)in 340 Edgar Tractrix horn, crossed at 6-7kHz with most probable 2nd order .Compared to TAD fostex was soft , warm , detailed etc. Sure, I know that in well implemented installation I should not be able to tell or point the sound of a tweeter but we just did basic comparison to get a rough idea of sound of those tweeters. Harlanov , I think that owner of the instalation in question specifically choose 500MKII for it's "inherent sound signature". I've met many who love those warm ping ,ping, ping treble sounds i.e "Cain & cain fostex FR " speakers crowd. I don't see much in this setup. In original form it looked like typical "cut & paste" Goto project but either the drivers were too fragile or more likely it just sounded to too thin and light so owner switched to horn loaded cone for more pronunced upperbass and forgiving mids crossed to "wet" tweeter. I know this sound. Some even consider it "world class" .Best Regards, W
