The problem is, from looking at the pics, I would *guess* that the D2000's ear cups are slightly thinner than the D5000s which means less space behind the driver butt and the back of the ear cup. This *could* affect the sonic signature of the mod, I have never mod-ed a D2000 so can't say for sure. I tried placing an additional layer of dynamt behind the butt of the driver of the D5000 and got major bass suck-out. I was told by someone I was communicating with that changing the amount of space behind the driver and inside the cup can change the Q of the driver response. Now I don't know what "Q" is, but I do know what bass suck-out is.
Here is what I advise you start with in terms of Dynamat:
A full single layer in the ear cup (if there is less space behind the butt in the D2000 as I suspect, you may want to leave a little hole in the middle of the dynamat behind the butt of the driver):
Notice in the above pic the little ring of dynamat around the butt of the driver, too. You also MUST leave a hole in the middle of the Dynamt you apply to the top part of the driver butt. there is a hole there that has to be able to allow air to pass.
Do you have Fiberloft? If so, apply a VERY thin
dusting of it inside the earcup. Pull it apart so its very light and airy, do not cram a lot of it in there. Ztake what you think is the right amount and then remove half of it (I'm not kidding don't use too much), hollowing out a little extra space behind the butt of the driver.
Seal it up and try that first. If you like what you hear, you are done. If you still feel there's too much bass wobbling and farting, only then add the extra strips of Dynamt that are pictured later in this thread.
OK?Please nobody else try the mod until I get it 100%. Thanks!
