Hi there! Another Q regarding Fostex T20

Do you think it is possible that T20v2 is available to buy nowdays? I found few on-line shops with pictures of v2 and from one of them I received answer they apparently do not have mkII but just T20 version.
Do you know when the mkII version replaced the v2?

I wouldn't get my hopes up about buying an old NOS T20v2 from online music sources. When I was looking about a month ago, I emailed two of the lowest priced vendors listed on Google's merchandise engine that were suggesting that they were selling older versions (the prices listed were around $50 for a set). I asked specifically whether the seller would clarify which version of the RP they were selling. What I encountered was a total lack of response from each of the businesses I contacted: they either did not know, or they had no inclination to clarify the issue.

I think that the T20v2s that show up infrequently on Ebay remain the best source of supply. I'm happy to be corrected (and will take note of any better suppliers).

On the other hand, if the shops that you've contacted *actually have the original T20 version*, there are a number of people here who would be interested in getting access to the oldest version of these phones. Kind regards.

Well you must be right, It is too beautifull to be truth... And though they said they had not mkII version... but actually on the product page is says T20RP. RP means actually this is mkII... As T20v2 was in fact no RP.

Sim1, if you haven't seen this, it is very good to ponder: Fostex orthodynamic headphone identification guide . Cheers!

If I want to try the micropore tape on the back of a driver like the T10, but I don't want to over dampen it, is it better to make a disc in the center or a donut?

 

[dBel84]

my limited experience - the donut has worked best for non-center riveted drivers and the "anti-donut" for the center rivet. "anti-donut" = outer ring with smaller center ring leaving an open ring between the 2.. dB

I do that front and rear of the SFI's, outer ring bitumen, center circle 3M micropore tape.

 

[BoilermakerFan]

Thanks Don, I'll try that on the T10s and on the YH100s.

Another question. I believe ericj mentioned 100 pages back or so (LOL!) that he had a link to sewing or whip finishing the nylon multifilament. Can Eric or anyone else post the link? TIA.

Well this round edged thing is your assumption, I think it more than likely doesnt exist in real life. You now have seen two square holed drivers with sharp edges. Most likely that Yamaha diagram is just some rough artist work, and it was supposed to be straight. Thats my guess anyway. As for the hole numbers, what kinda significance would you assume (or now know) this has?

It would mean lower distortion. not to mention the fact that just because you cant audibly hear above 22050hz, doesnt mean that you cant perceive any frequencies above that.

Couple of teaser pics:

rythmndevils' YH-100s are getting new shoes!

Had to pull them off and mod them a bit more, the CA glue is setting and I'll put the pads on the adapters tomorrow, then rubber cement the adapters with pads back on the YH100s and listen. I have high hopes that I won't have to touch Ludo's original dampening.


Then I'll make a set for my YH3s and KH-83s...

Boilermakerfan: not quite sure what your doing whats that blue stuff for?

New Stuff!
Everyone: If you remember a few months back I found someone developing new Planar Magnetic headphones. Well if you are attending the upcoming CanJam '09 in LA you will be lucky enough to see them for their world unveiling and have a chance to demo them.

I really hope someone does and reports back to us here in the thread.
The Company is called Audeze, and they will be at Catalina 2B. There should be some guys called Alex and Sankar running the stand. Say hello to em for me (and a shout out to the ortho thread!) if you get a chance to go there!

I am not sure if I am allowed to post the website and all the details yet....
What the heck I'll post the specs and blurb, it is free advertising after all

Drivers can also be used as high quality mid/high frequency transducers in two way or three way speaker systems (300Hz-50KHz). • Transducer active diaphragm area: 5 in2 • Impedance: 20 Ohms, purely resistive. Can be designed for different impedance values in range up to 50 Ohms. • Input cable: 3m with 1/4" stereo plug • Contact pressure: 1.5 N • Self adjustable, comfortable Headband • Weight: 250 g, without cable Features: Planar Magnetic Transducers which provide uncompromised high resolution sound suitable for the most demanding High-End home or professional applications Magnetic Structure - Specially designed self closing magnetic structure with high grade Neodymium magnets. Lightweight, with uniform magnetic field distribution. No steel used for magnetic return path. Acoustically transparent. Push pull construction provides absolutely symmetrical driving force with extremely low distortion. Diaphragm - Very lightweight, precisely stretched compliant film with conductive traces that cover more than 80% of the diaphragm area to provide uniform driving force across whole surface, with extremely large acceleration values for very fast transient response and life like sound reproduction. Mass of the diaphragm is comparable to the mass of air it disturbs. Due to linear magnetic field, diaphragm is driven with linear force resulting in negligible distortion, even at full output. Strong, uniform magnetic field, large diaphragm area and large magnetic gap allow high diaphragm excursion of 3 mm p-p for very high Sound Pressure Levels. Maximum output exceeds 120 dB. Special acoustic damping material was developed to provide proper diaphragm loading of the rear diaphragm output for excellent resonance control and low distortion. Completely acoustically transparent earcups to prevent reflections of the diaphragm rear radiation. Open Air construction enables small crosstalk between left and right earcup for improved out of head sound imaging. Large diaphragm area creates plane sound waves that enter ear canals the same way as it happens in real environment. This dramatically improves sound imaging. Left and rear transducers have matched sensitivity and frequency response within 0.5 dB. Exceptionally comfortable to wear due to elliptical design of the earcups and ear cushions adapted to the shape of the ears. Ear cushions made with velvet finish for extreme comfort and good sealing for excellent bass reproduction. Can be directly connected to stationary hi-fi components of the highest quality, in particular SACD, DVDA and CD players. Due to purely resistive and linear impedance used equipment will always sound better with these headphones.

that blue ring are there to replacing original pads or just for a spacer under earpads ?

New stuff?! Cool. How about the $?
