Here are the step by step pics to the blu-tak mod (although I used "white-tak", not "blu-tak" for this particular mod. Same stuff, just a different color).
A900's before any modding:
Starting to remove an earpad:
Continuing to remove the earpad:
Earpad off completely:
Removing the screw that hold the earcup together:
Driver section removed entirely from the earcup:
DADS system revealed on back of driver piece:
First step of removing light grey foam donut:
Second step of removing light grey foam donut:
Removing the black foam strip:
Black foam strip removed:
Picture of the blu tak (white tak in this case):
Starting to coat the cup with blu (white) tak:
Cup completely coated with blu (white) tak:
Cup with all cotton added to the top of the blu (white) tak:
Bass Tuning
OK, what you will notice with this is that the deep bass will be a bit less, the upper bass will be thighter, the mids more forward, and no echo in the highs. Bass can be boosted by adding more cotton, or putting the grey donut foam back in. However, this will result in a slight attenuation of the highs. Personally I stuffed the hell out of my a900's for the better bass and slightly softer highs (the above pics are not of my a900's, mine have more cotton than that). Anyway, now that you can see how to get in there, you can experiment with foam and cotton stuffing to tune the sound of the a900's to whatever type of sound you most prefer.
Hope this helps!!
