Grado "Black" mod + DYI "Superbowls" on page 3.
So i've got my first Grado cans a couple of days ago, SR 80. Even though i liked their sound overall i couldn't resist an urge to tweak them a bit.
The first thing i did not like it's infamous silver lettering which are really low quality. The letter 'G" was accidentaly half-erased on the first day. Foreseeing the progression i decided to remove all of them once and for all to avoid ugliness. Also, i'm not a huge fan of plastic grills(i hoped the grill would be metall...) and buttons on grado cans, so i've installed metall grill instead. I think the result is quite nice:
But i not calling that a "Black" mod just for looks. There's something that was too much for me in Grados - their brightness. As a mostly Senn guy i found their top end to be a little harsh on some songs and bass are just a liiiiiiltle light for me. So i found the way to make them a little darker and shift the tonal balance down low for some(not big) degree. Here's how: there's an acoustic screen on the other side of the driver, which are damper for the membrane. You can alter the sound of the driver playing with damper. No damper usually means a lot of bass but rather uncontrolled; by varying density of the damper you can alter the sound. To allow a little more membrane movement and allow the bass to show up a little more just make some holes in the damber. It's basically a paper so little screwdriver and you are able to poke it. There's a plastic surface with a holes under the acoustic screen, to find where the holes are placed, just look through the driver on the light source(table lamp will be fine). Be careful and not insert the screwdriver more than couple of millimeters deep because you can damage the membrane. The more holes you poked, the more bass will show up, but, of course, it will not make AKG K81 DJ out of your Grados, it's a tweak, so changes will not be dramatic.
I started with 4 holes(as on the pic) but eventually poked all of them(10-as shown on the last pic). So you can gradually increase the quantity of holes until you satisfied with the bass. I think 5-6 holes will be enough to noticeably increase amount of bass. I've found there's too much bass with all 10 holes exposed, so i will cover some of them.
Just wanted to share...

cool mod, these look quite a bit better than the stock sr-80.
i'm not too familiar with the grado sound having only listened to sr-225 and ms2 for a brief moment so i can't really comment about the sound and adding bass to it.
still cool, though.
also, you should add some ram to you comp.

The more holes you blow out the back the more bass you get but the sounds gets bloated from lack of dampening in my experience. Don't forget you can add a bit of dampening to the metal part of the driver as well.

sorry if i wrote it in a way that wasn't understood.

There's no lack of dampening, it's just some "face-lift". Adding other dampening isn't necessary since they sound just fine.
Wolfskie, ok, i got it. Was in a hurry uploading pictures, haven't noticed that pop-up sneaked in there, thanks!

The dampening I was referring to is the paper/felt covering the holes not the badge, I found that it made the bass too "loose" for my personal taste. ymmv.

Possibly an amp issue. Bass is anything but loose. Never tried them unamped though.

x2. I did this on my old set of sr80s and I thought that they ruined the sound. All the treble left and I was left with bloated, muffled, crap bass...just my 2 cents though of course

If I remember correctly, it looked pretty similar to how your holes are spread out. Personally, I did not like it.

I had the exact same experience and results about 10 years ago. Took a couple of days for me to realize I had totally f--ked up my SR80.
