Nice, did you put some stain on that Limba?

No...the sleeves are mahogany, that I tried to stain a deep red color. I didn't like it, so I sanded them and used Tung Oil...so it's a mix of those two over mahogany smily_headphones1.gif

Hey guys,

 

I have discovered something rather unique with Grado rs1i's (burn in about 25hrs)

This was noticed after comparing to my Grado Sr80's (pink drivers) the mids were slightly recessed and tops pushing a lot on the rs1i's.

 

 

So i then discovered serendipitously that covering the air vents cup opening with my hands slightly would change the sound signature.Then I thought what could I use to slightly close the vent rather than the open air...?

I looked around and saw some scotch tape and placed a strip across the vents at 180 degrees and wowza the mids and tops are now neutral along with the bottoms producing a spectacular sound which is extremely neutral.

 

 

Now they produce a amazing reference sound and I can't guarantee what yours will do but if you have these rs1i's wooden cups or perhaps rs2's,gs1000 anything with the wooden vent openings place the scotch tape across the vent like in my picture below.

 

 

Sound signature is taught, imaging is locked in and its extremely flat across the freq range especially bottom to mids and tames the harsh top end of the rs1i's. I am now on par with my pink driver sound(flat and accurate) which i extremely prefer.

 

Good luck and hope this helps others with these looking for better accuracy :)

Interesting...

Will have to explore this

Indeed.
I am quite shocked and gave feedback to Grado.

For something claiming to be reference it hardly is more apt is "fun" and considering the price I paid extremely disappointing. Thankfully the cheap fix creates a flat neutral sound which is more akin to reference.
Surprisingly my grado vintage sr80's with pink drivers helped in ascertaining what was missing. Yes a 15 year old prestige series headphones. Makes you wonder doesn't it?
Good thing you can remove the scotch and return to fun sound. I prefer the scotch tape mod overwhelmingly.
Please post your thoughts curious if others have similar findings.
