A proposed mod: ( for "even better" resolution to the bass..enhanced separation n more depth...to my ears
)
If u open up the cup, u will see the four screw posts....
Roll up some blue tac slightly smaller than the diameter of a typical straw...
2 phial for each cup.
Line it from one post to the next screw post along the Longitudinal sides of the cup,
As if u are trying to funnel the sound waves to the 7holes vents at the top n bottom of the cups.
Press the driver n cup back firmly n tighten the 4screws, some blue tac might ooze out from the sides,
If u applied way too much blue tac, u might not be able to affix the screws.
The diffused sound leaking from the sides of the cup is cut out....
The cleaned up bass provides a " blacker" canvas for your listening pleasure.
This is especially telling on my angled velor pads,
Still discernible on the stock pads if your ears are sharp, but might not matter to some folks
* I didn't take any foto, sorry...i tot it's a crazy idea n ....lazy, until my next itch to open them up. Give it a try, if it works for u, let me know.
* inspired by Light-Man's lifting of the veil off the holes thru cottonballs.
