Just listened to some Fostex T50RPs today... WOW!

@fleasbaby those look fantastic. I'd try adding some damping first. Usually a small container means less low end.

I have done a little listening and realized that if I turn off the bass boost on my E12 (duh) everything is rather nice and normal. Lower frequencies are back in their proper place...the smaller cup with no damping also seems to require less pushing. I turned the gain off on the E12 as well...

I am now looking to make a fresh pair in Mahogany. Also planning on experimenting with alternative methods for screwing the cups to the baffles so I can get in and out more frequently with less damage.

Can the screws be used from the stock cups by chance? Although you'd need taps and counter sinking bits

Hi Guys, I know it was here but I wanted to ask for more info. I have read that previous version of driver for t20rp with white plastic enclosure is worse in performance. But I wanted to ask if diaphragm is same as recent. is it only dampening on it different and magnets? I recently purchased two pairs of t20rp's and one of it is older type (both were actually looked same outside, only jack plug was different). Anyone can share thoughts about previous driver?
 
also has anyone tried replacing of magnets, or adding something like another layer/rows of magnets on top to make them stronger.

No, those aren't suitable for wood...I am going to explore my local big box hardware store and look at options...requires some creativity I think. Might also require altering how the inner cavity looks a little, which will probably screw with the sound a bit, so Pandora's box has been opened

fleasbaby, those look amazing. 
 
I'm still trying to mod with the original plastic shells.

Do a cup/baffle so the Rear Cup Component is removable and you don't have to take off the pads and baffle screws each time you want to tweak the tuning.

I saw that Stratocaster did that with his Fostex mods...it might be worth exploring...at least for a pair I can return to for tweaking before making a final version with a fully closed single piece cup....

Yes, Stratocaster, symphonic, and several others have done Rear Open mods. It cuts down on tuning time and saves pads / baffle screw receivers.

...going to search for images of how symphonic did his....I have seen Stratos...as always his work looks immaculate

*edit* might be because I am fumbling about on my phone, but battling to find symphonies images (if he posted any). Can anyone point me to them?

Just want to know by getting a balanced cable for my t50rp, does it mean that the headphone support balance setup? Assuming I have a balance input for this headphone....

 

[PETEREK]

You would have to wire them to be balanced, you can't just use the stock 3.5mm input. Any headphone can be made balanced.

I'm assuming you can't use the amps 3.5mm or 1/4" output either? As that wouldn't be balanced of course

 

[PETEREK]

Those are both shared ground connectors, so no that is not balanced.
