SR60-Mod part II - Page 223

post #3331 of 3341
Interesting. Hopefully I can make them within the next couple of weeks and see how it goes.
post #3332 of 3341

So. Sitting next to me is a set of  B-stock sr60i 's and a really old set of sr60's. From a whole lot of ABing them i actually prefer the timbre of the old sr60's, it might be the condition of the driver (when I got them the gauze front was yellow and the pads were crumbling to dust) but the upper end is strangely textured - but subtle, and in a really sweet way. While the sr60is have more bass they sound less friendly to me.

Then came modding.

sr60's:  I punched two vent holes and lined the chamber with a thin strip of felt. Bass was bigger but quality much less. After removing the felt the quality came back! I haven't heard anyone else mentioning chamber damping affecting bass quality. Also the two vent holes bring the bass up to about the 60i level.

 

sr60is: Felt lining softened the sound, Once again I removed it to bring back quality but with the bigger chamber you can line the cup-inside as well as the part joined onto the driver so right now I've left the felt on the removable cup part and button. I also put a circle of felt on the driver back plate, seems good.

 

Why does lining the chamber reduce quality and increase bass?

Also will masking tape or J-cloth do to cover up vent holes? thats's what I'm using now to compare the difference.

From my experiences lining the walls with felt with an SR60i, the scale of the sound became smaller and there was less 'air'.

I've read from different sources that the chamber dimensions behind the driver are carefully designed to produce the correct sound... playing around with it leads me to believe that it is correct. 

 

I found that the most important Grado mods are done ear-side (aside from vent-hole-punching) with different pad sizes, hole sizes, pad materials etc.

I agree there, shrinking the chamber won't help anything. I just swapped the cups between the 60 and 60is. The old 60s sound  good with the larger cups, the sound opens up and feels less inside the ear as you'd expect. Better synergy with the venting too.  If only I had some wood...

Has anyone tried to mod a newer "e" series?  Or are the changes made to the e-series make some of the mods built-in?

post #3336 of 3341

I just opened up a SR 60i and the drivers say "Grado 32" with a red dot. Any particular significance there? 

post #3337 of 3341

I have new SR60 and thinking about mod (origginal ones sound kind of ****ty, I hope it will be better). It is hard to read 250 posts here so I have just few questions:

 

1) Is there any plan for wooden cans with dimensions? If someone has well sounding shape of wooden cans, can you please share dimensions?

 

2) Or best way is just copy current design cans to wood?

 

3) Is there any rules e.g. thicker wall -> more/less bass?, longer cans -> xxxxx?, wider holes in cans -> xxx?

Quite spectacular. Any chance on a tutorial [even the most rudimentary, ie text form only would be appreciated]? Apologies if previously answered. Am only partially forum deep

What are the rod ends on the blackwoods? That's such an interesting texture

Hi guys, posted this same question in the impressions thread but only just realised so I don't think it'll be of much help there, does anyone have any tips on prying the shells apart using whichever method? I've tried steaming them and pulling them apart, heating them with a hairdryer, nothing seems to work for me. Any tips on the steaming process would be greatly appreciated, in terms of how long to let them sit and any particular method of prying the shells apart. Thanks.
