Fostex T50RP Incremental Mods and Measurements
Mar 28, 2017 at 9:08 PM Post #2,311 of 2,844
I have a T50RP that I modded by adding plasticine, some cotton and removed the covering on the ear side of the drive. Even with these mods the T50RP was anemic and thin sounding, I much preferred my modded Grado SR60i but the wife always complained that my music was disturbing her so back to the T50RP I went. I decided to get a pair of the ZMF lambskin oval pads with I installed today. All I can say is wow! These pads made a much bigger change than I expected, the phones are no longer anemic, now there is plenty bass and I am hearing low end details that I never heard before in familiar music. I have some wire and xlr connectors on order so that I can go balanced.

I love that leather seal. :)

Several others have had this problem. I've replaced 5 or 6 diaphragms for guys because the faulty ones were warped. The hypothesis is that the warped diaphragms vibrate against the magnets due to greater excursion from bass freqs. I think I posted pictures within this thread; maybe the first post.

Noticed some chatter about wood mods for T50RP, so I decided to also post the link to this thread instead of just the MK3 thread. :)

Very nice! Mine are almost done, I think. How do those sound? As beautiful as they look?

Yes. I should be sleeping right now but I'm cycling through genres again... they're so pleasant. I purposely added no dampening or any filler to the cups, I wanted to really know that the wood was doing all of the work. Gabon Ebony and I are long-time friends, a favorite clarinet of mine in my youth was made of it--a lovely distinct color and smell that you'll never forget.

That's fantastic, I hope to have my father in law whip some up out of xoxobolo after he's done with the black limba. The cups are press fit to the custom baffles,making it easy to deal cups/mod cups. Can't wait to see what he does with it all

Cocobolo is a beautiful wood! I'm obsessed with Gabon Ebony, which is REALLY expensive and difficult to procure. Luckily for me, the SO's family owns a few hobby woodworking shops.

Good day, which mod version/variant is considered the best in terms of providing super isolation (best sealed/closed can) with a non-fatiguing sound signature and long-term comfort?

My preferred music genre is slow electronic (ambient, classic, downtempo, new age: e.g. Jarre, Vangelis, Schulze, Eno, Grosskopf, Enya, Lana Del Rey, Pyrdz, etc.).

Considering the following:

Mod Foundation Kit: Use the Mayflower kit with the baffle upgrade as a starting foundation to work from with any/all required additions to improve the isolation and get a non-fatiguing sound... what say you?

Ear Pads Mod: ZMF Lambskin Ovals or MrSpeakers Alpha Pads

Head Strap Mod: ZMF Lambskin Pilot Pad; MrSpeakers Leather Comfort Strap; or ModHouseAudio Deerskin Suspension Strap​

Best isolation I think goes to the Paxmate lattice mod - that thing beats pretty much any consumer/fashion/studio closed-back headphone for natural attenuation.

You can also add paxmate around the front of the baffle for a tiny bit more isolation, and doesn't hurt the sound either.
