post #7246 of 7259

So here's how to kill that grating 2khz peak in your ear.

 

I deduced (induced) that it was caused be the middle dome of the driver breaking up, and the rest of the higher treble was made by various breakup modes in the 'cone' part. I put a "7/16 (11mm) diameter piece of tape over the center hole (my sr-60i have the cloth still) in hopes of getting some phasing action to cancel the frequency somewhat.

 

I experimented with different tapes. Don't use any tape (duct, gaffer, masking) with white adhesive, it will eventually turn to white powder or cement. Use tapes with clear adhesive. I found regular matte 'invisible' office tape to be a good proof of concept if you want to try it, but a little bright, still. Good 3M vinyl electrical tape was a bit too dull, with weird highs. The best, which sounds great is 'Scotch Decorate and Repair tape', which of course is no longer made. It's just cheap vinyl tape though, very thin, like you'd find at the dollar store.

 

edit: Sticking the tape on the inside of the pad works just as well, but put your various test tapes over the hole first, because you'll be pulling them off, and putting them back on, and pulling them off again. The foam might deteriorate.

 

edit2: actually, that works better.

 

I have SR-60i's with s cush.

 

I hope this helps you love your Grado's, I love mine.

I found straight ahead female vocals a good thing to listen to to tune this..

That's a good idea for replacing the grille cloth, ladies nylons would probably work well. Was meaning to quote the person I'm replying to, but I'm still a little unfamiliar.

I stopped using them because I wasn't a big fan of the sound, I was planning to do the Ms1000 mod.

 

While I haven't removed the gauze from my Grado cans yet, I've been using silk organza for the grill mod on my Hifiman headphones, a finer mesh but more transparent acoustically according to a friend in a testing lab (testing for material data sheets information).

Anybody have a Grado headphone cable they would part with? Prefer 8 conductor.

I have 2 of them, I was going to strip the outer plastic off and just re-sleeve the wires to make a 4 wire cable since the 8 wire is just too heavy.  One is from a SR-225e and the other from a SR-225i.

 

Where are you located?  How about $15+shipping since I don't know were you are located.

Where is a good source to pick up some stainless steel mesh to mod my SR60e hps?

 

Thanks

I use a pencil holder I buy at the dollar store.

I was hoping for stainless steel if possible, but the pencil holder is a great idea and cheap too...thanks

I used a kitchen sieve. 

No idea if it's stainless, but it certainly won't rust whatever it is. 

 

You can even pick them up cheap in £1/$1 stores if you're lucky, even with proper woven mesh, not a single piece of 'grill'.

The clear part?

That's the driver. Damaging that will destroy the driver.

Already looks half way destroyed to me.

Those indents on the diaphragm need to be popped back out VERY carefully.

 

Without doing so can likely result in some buzzing at lower frequencies and distortion.

 

You will need something thin and small like a pencil - DO NOT use a screwdriver, as the driver magnet will jump up to the metal of the screwdriver and will damage the driver even further.

Then put a small piece of double sided tape to the end of the pencil/pen (or similar wood/plastic thing) - make sure it stuck on PROPERLY - you don't want it coming off and getting stuck on the driver.

Then gently press the tape directly in the center of the indent(s), pull the dents out gently until the entire diaphragm's uniformity is restored.

Hey grado modders, I need some help. Can any of you guys 3D print me a pair of plastic sleeves for my drivers?
I liberated some drivers and broke the plastic sleeves to get to them, now I want to go back to stock-ish. biggrin.gif
