Fostex T50RP Incremental Mods and Measurements - Page 107

post #1591 of 1605

Do you guys think it's worth buying the mrspeakers lambskin pads for these? In addition, what about the Audeze LCD pads?

post #1592 of 1605

Actually, to clarify I also wanted to know if the Audeze pads would fit without modifications akin to the SRH840 pads?

I uploaded a link to Google Drive for ARTA Setup Guide and Pictorial for Beginners.

 

It's located in Post #1 of this thread in Chapter 4 of the Table of Contents.

 

ARTA is a powerful audio suite of measurement tools and alternative to REW. ARTA generates FR Magnitude and Distortion graphs as well as very slick looking CSDs. I hope my guide makes ARTA easier to setup for everyone.

 

Kudos and High 5's go out to hans030390 and stratocaster for helping me find my way.

 

Cheers,

An edited version is now available at the same location as described, above. Anyone who has trouble downloading the Google Drive document can PM their email and I'll send a pdf.

Just curious which mods contribute most to closing the headphone up?  Closing bass ports / Stuffing with cotton or wool / mass loading baffles.....  As an entry level modder, I would suspect all of these (some contributing more than others).  What other steps would contribute?

 

Also, has anyone ever tried experimenting Scotch Brand 2228 electrical tape in a mod?  It's somewhat popular in the mountain bike community for frame protection as it's pretty tough stuff.  Thick & rubbery.  The adhesive is very strong however so if I were to experiment I'd probably layer over standard electrical tape first.  Just throwing that one out there.

If the goal is sound isolation, the paxmate lattice mod was EXTREMELY isolating.

Placing more on the outside of the shell would surely increase the effect.

DIY Headphone Measurements

 

Frans (aka 'solderdude') performed some revealing experiments comparing Panasonic WM-61A mounted on an Etymotic triflange IEM tip that goes in your ear vs. mounted in a DIY dummy head. His report of results is a Must Read for anyone using these methods.

 

Frans' measurments of many headphones are also interesting.

 

Links to both are now available in Post #1 in this thread - Chapter 2: "DIY Measurement Kit"

Hey sorry I missed this question. I did not make the headband strap, Lohb did. But yes, it is beautifully made.

So while waiting for new wood I decided to salvage the cups I messed up...the friction fit I wanted isn't there, but they work. More improvements planned for the next try (lower profile baffle for more space in the cup, another try at bass ports...)



The cable is simple Mogami, stripped from the Y, which is only heat shrink. I suppose at some point I will remove the ZMF stickers from that headband smily_headphones1.gif

I love your cups!

 

Can those be purchased? My love of the T50RP is growing. Finally have it tuned to near perfection (for me) and happy enough to invest more $$$ into them.

Thanks...I just shot you a PM.
post #1602 of 1605

So I've been thoroughly enjoying my 'Nickerfied' Make-Up-Pad modified T20RP MKII for quite a few weeks... (months?)

If however like me, you find the treble ever so slightly too piercing or just a bit too forward on some recordings, there's a very simple mod that I find works for me to just take the edge off.

(I do have a preference for slightly rolled-off treble, or 'darker' sounding headphones.)

 

Under the 'bluemonkeydots' (as described on page 1) is a thin gap where the adhesive backing has been snipped away.

Simply place in this gap a thin piece of soft 1mm creatology felt. It should cover/fill the entire length of the hole but be slightly thinner than the hole, as it will most likely try to expand and may peel away the paxmate adhesion if the felt is slightly too big.

 

No idea how it measures, but my ears like it.

That's it.

Wow, the 3D printed wave guides look really cool. Perhaps I missed it but what do I need to do to print some myself?

Hi BSH,

 

Send a PM to SenCreaTive.

 

The ones I ordered from shapeways <.> com should arrive, tomorrow.

Once we finalize the design I'll put them up on shapeways to either buy at cost, or download the file.

I might make a few different versions, like a single print pair, or part treeless ones for home printing.

In short you'll just need a 3D printer. If you want to make the print smooth instead of having a bunch of ridges l, you'll have to make sure it was printed out in ABS plasic. (Most common anyways) then Google the smoothing process. Seems rather simple, I've never tried it though. You don't have to smooth them out, but I fear the ridges may effect sound reflection
