yep, this phone sounds miles better when the earpads are angled...there's a huge gap in the center otherwise, and the SS is really meh.

Thanks i will give it a go

 

Is this the baffle hole that should be blocked? I have marked a red ring around it.

So when angled, my t50rp's lose the veil in the hi mid and the center is back in the soundstage.

Yes, the directivity of large planar drivers in a free field environment is important.

 

Due to the extreme near field environment and the small size of the driver, directivity is not an issue at all with regards to the headphone environment.  Reflection and acoustic shadow caused by one's pinnae is worth taking into consideration.

That's it, I think.  You should cover it up on both sides.  On the face, it is the only hole, you can't miss it.

Thanks, i will cover that with all the rest of the holes

Finally finished modding mine today. I used Akasa Paxmate plus and Dynamat Extreme rolled into a ball, The vents are fully open at the minute but i will tune them when i have some new pads.

 

I also ripped all the felt off the face of the driver as my knife wouldn't cut it. This has made the highs a little ear piercing but i think its because the driver is pretty much touching my ears with the v1 pads.

 

Overall they sound great, Better than the 650's or d2000's

 

I'm going to get some sure pads and put some thick felt on the back of the driver and i should be done biggrin.gif

^^ that puts my work with the akasa to shame...ph34r.gif  Well done.

Hi did you manage to fit these foams so nicely ? Can you provide some details on how you fit the foam on? 

I also suggest replacing the white stock diaper with thick felt. It does the same job except that the felt would not produce harsh highs at all.

He used one full sheet and just layered it over the back of the cup without cutting it into strips at all. 

 

I tried this and did not really like the results, it was a bit over dampened for my tastes.

Had the phones in the office, someone tried them out and said, "wow, how do these make the space sound so big....

Just thinking that now with Zero 7 on....
post #1586 of 10610

Thanks. I just used some A4 paper to make a template to size.

 

I'm not sure where to get the felt, is there a good place on ebay.co.uk to get some?

Do you have a pic?

I never really thought about over dampening

Felt is easy, just call a few fabric or craft stores... Thick wool felt and stiff craft felt seem to offer the most potential....
post #1589 of 10610

So there this fabric store down here that used to be painted like some hippie paradise (I only learned like a week ago that it sold fabric) so I walk in looking for some felts and couldn't find any stiff felt.  I told the lady behind the counter what I was looking for and that I was modding some headphones and she goes "well, we have a stereo department so maybe they could help you out."  I thought this was bizarre so I walk over to the stereo department and was greeted with Martin Logans and Magnepans everywhere.  It was a bit like Alice falling through the rabbit hole.  I got to talking with the sales lady and she said that they only sell Grado headphones now but they used to sell Stax. 

 

They actually have a website: http://www.readbrothers.com/

 

I didn't get a chance to demo anything because I was sort of in a hurry but I would have loved to demo some of these speakers.

Nope, dont have a pic.

 

The thing is, with the way you did it, it leaves less airspace in the cup. Cutting it into strips and layering it on is more precise and leaves no gaps of air between the back of the cup and the adhesive part of the paxmate. More breathing room for the drivers should have positive effects for both the bass and soundstage.
