Firstly I just put the sticker over the dust mesh inside the HD800. Then I got sick of it falling off so I pulled off the mesh carefully as...
I have just trimmed these absorbers to 4.5mm depth and retested using Audacity. Now my 6kHz band is very even with the 5 kHz to my ears and the...
Ok, just spent an hour with my wife and daughter where we listened to test tones 5 kHz, 5.5Khz , 6kHz and 6.5Khz to identify which was the...
Late last night I tried a different type of foam. I took the bungs out of my speakers and in the name of science I cut them up just enough to make...

Just reading through all the mods and noticed your filter paper mod on the centre of the driver. I did this recently with a light paper sticker on...
Yes but I just did a simple experiment with a paper sticker but have ended up really liking the result. With my HD800 the 6Khz peak always seemed...
No, it's not happening for me for some strange reason, gives me an 'unable to upload'. Still, its a simple paper sticker that only covers the...
Stupid me can't upload a normal jpg to this site so have saved it to my avatar.
