Today I am pleased to be able to reproduce an article which my friend on Head-fi, Stacy of sarn-industries.com wrote on the modification of the Audio Technica ESW-9 cans to give better reproduction and better overall sound stage presentation. Kudos to Stacy for allowing me to reproduce her wonderful article.

Hey guys,
I thought that I would post some of the modifications done to my pair of ESW9's that was picked up last week (delivered beginning of this week). As with any of the modifications that I post or do, they are all reversible.
NEEDED SUPPLIES:
1 - Pair of Scissors or Xacto Knife
1 - Small sheet of Damping Foam (I used Sticky-backed 1/4" EVA foam)
1 - Quarter (as in $0.25 American)
1 - Pencil
A small amount of polyester or cotton stuffing
STEP ONE:
Remove the Pads
STEP TWO:
Remove the Black Woolen film (we won't be putting this back, but you might want it for reversing)
STEP THREE:
Open up the cups with a small screwdriver (be sure not to loose the screws)
STEP FOUR:
Remove the creme colored batting from behind the driver
STEP FIVE:
- Trace a Quarter FOUR times on the sheet of damping foam
- Cut out the four circles
- Cut a small hole in the center of each (just like teh small hole in the center of the driver)
- Take two of the circles and proceed to cut them into thirds (Layer 2 - step two)- Take those pieces and trim them to look like Layer 2 - Step 3
STEP SIX:
- Place the Layer 1 circle on the back of the driver, making sure that it is centered.
- Place the Layer 2 pieces on top of Layer 1 just like how they were cut in STEP FIVE (should look like a radioactive sign)
*The layers stacked should look like above*
STEP SEVEN:
Assemble the cup back together with the screws
STEP EIGHT:
Put the pads back onto the headphones
STEP NINE:[/B]
Stuff under the back half of the pads (the part that sites at the back of your ears). This will create angled drivers.
STEP TEN:
Listen and Enjoy!
****BASSHEADS****
Don't add the LAYER 2 of the Damping Foam and be prepared for head-knocking amounts of bass.
As a side note to get the EVA foam stuff.. RadioShack is clearing out all of their Thermaltake stuff. Pick up their computer damping kit, it uses the same foam and should end up about $5-7 with plenty left to damp your computer or just whatever.
Cheers!
