Hi Romy, If you scroll down to the bottom of the page, there are 3 units supplied by Fostex: http://www.madisound.com/cgi-bin/index.cgi?cart_id=1455929.29661&pid=315 Neil...

"This topology was invented by Steen Duelund"Ah-hm, ring radiators where not invented or even re-invented by the Steen Duelund dude, just copied. JBL used the priciple 40 years prior to that in: 2402-2403-2404-2405 and Fostex have been using them al...

well, i believe that the popularity of the better fostex tweeters comes from their typical, off-shelf sound which is soft and easy on ear in comparison with super-resolunt Ti or Be diaphragm equipped competition. they very much suit any sharpness com...

I got my pair of F120A by-the-book bookshelves a few weeks ago and yes, in the beginning they were very much "compressed" sounding. Things improved a bit over time, but the low treble (which gives instruments their "color") is still recessed. So I ...

Actually it was sad to hear potentially nice horn system wasted on mediocre music (at least that's what I heard at three different times I visited the room so it must have been a norm ) and grey sounding D-amps with "pumping " bass tubas. At least th...

[quote user="moreart"]oh yes, show me ![/quote]Just an example:I can show you at least 20 other backloaded horns with different drivers which I have heard here in Bulgaria.Moreart, your main problem is the quality of the drivers you use. All those fo...

thanks for the good infoactually we are developing a full horn-loaded speaker the bass-bin is just inspired by Klipsch La Scala (just like Volti speaker) with curved sides. the mid-range consists of TAD 4001/Beryllium in Edgar wooden Tractrix horn an...

Hi Murataltuev,I have two horn based systems but the system that is similar to yours or Romy's is the one I am currently building. The drivers and horns are as follows.38hz - 160hz - Tad 1601b - Bass Array (4)160hz - 600hz - Supravox 285-2000 hornfab...

I'm giving myself high fives today for nearly solving the broken piano sound in the room. :-)I'm not sure what fixed it, but I believe it to be a shelf half filled with records + two sofas and a carpet.There is room for improvement but it is a g...

I am taking about a “Default Evaluation Loudspeaker”. Let pretend that all people who do SET appointed one single full-range driver: like some kind of Fostex of Feastrex… and all agree that the driver is placed dead center of 100cm by 100cm open baff...

Yes, Paul, I did not think this way but you are very correct. Technics TT, Denon 103 cartridges, Fostex speakers, “single girl with balalaika” music and Adcom CD players are kind of come along all together very well. It is not that I have something t...

Romy,You provided very good starting points on the driver selection and I am also corresponding with a gentleman that may help me with actual horn design. I have found a couple of drivers that seem to work based on your guidelines. They are pro sound...

Some years ago I've read on AA how great Ratt Shack 1197 (fostex f-103) drivers are (for whooping $2 a piece ), and some high-end German guys refuse to listen anything else than those Zigmahornet pipes. They are OK for background music and maybe for ...

Hi Romy That's an interesting point! Very interesting. Why mids and highs should have a super light membrane and strong magnet to follow the rule of precise movement, speed, resolution, etc....While in lows its better to run muddy with heavy soft mas...

I have listened to some expensive speakers from B&W, Wilson Audio, Dynaudio, and also owned the SF Amati, you know already. Musically these ones were more musically interesting to me than any of the others, but still weren't something that comple...

Hi all.I am just supplying a couple of threads that are dealing with application and the theory behind the EnABL process I provide information on here last year. Romy, you should not go there, it will make you crazy and you will have to insult someon...

...no sarcasm was meant, nothing to "read between the lines." Several people seemed quite impressed w/ 138s in DIYaudio thread early on, said no tweeter ever needed, best mids they ever heard in anything, etc. That was part of what prompt...

Romy, I suspect that 200 Hz high-pass will be too low for that driver, even 2nd order, and almost certainly with just 6 dB roll-off. I think more like 500 Hz with 1st order, and might still require the coil.Yellow-type drivers take on and ...

Another tool used by sound pros is LEAP. The guy who designed my BassZillas (some time ago) used this tool to make the most of a BR enclosure. As for the Fostex (U)HF, the pros tend to correct them digitally, as they need "something". Mainly, did you...

Hello Romy,Here are some photos of what's been going on here: http://www.webbtjanst.se/lenco/loudspeakers.aspThe room modes I thought I had to battle suddenly disappeared the other day when I decided to try stuffing the boxes a bit. Suddenly everythi...

This is something I have been at for the last few years, I have tried a few drivers, at the moment some of my favorite are the vintage RCA MI 1443, yes filed coil and some funny cone diaphragm, they are used from 500 hz to 5 khz with a Fostex T...

Hi Paul. Clear now. Well that "horn" actually adds a slight 6dB boost from 200 upwards, fading out around 1k. I assume that was just the missing piece to make most 8" driver (thats actually a fullrange) pretty flat up to the top. And likely what the ...

How about the 4" Fostex FE108E? http://www.madisound.com/catalog/index.php?manufacturers_id=131&sort=3a&page=1 It's only too big by 0.080", and if that bothers you, it would be easy to chuck by the magnet, & turn that off ...

Got last night the last bass drivers for MiniMe’s bass sections and put them all together. Even thought I still have problems with MiniMe uppers channels (the Fostex F120A drivers are still hatching) but the bass sections turned out to be very good. ...

I believe that those "allien sounds" are an enhancement of the frequencies comprised in what is called the singer's formant, which is the area of the third formant when opera singers sing vowels. That area is in the range of 3.5 to 5.5 KHz and is a s...
