I've got the D5000 and love that sub bass.

Trust me, I've spent 2 weeks trying to EQ and DSP these the way I want them too, but it always started distorting when it got close to how I wanted it to sound (I love me some bass long time).  When I did this, the results were so good that I just had to post them here :).  And I seriously doubt this is irreversible, all you have to do just block the three holes with anything; tape, sticky tack, etc.  This mod + EQing =

It is pretty difficult to distort unless it is insane bass. Make sure that you haven't gone above 0db when doing digital EQ.

I just tried the mod to my PRO550s, opened 2 holes. There was a slight bass increase but I felt an overall loss in quality : / everything got kinda.. airy and a little more noisy.

Hmmm.. Right now I love the way my 780 sounds, but maybe sometime down the road ill try it.. Thanks for the tip!! 

Is it possible to do this to the ATH-M50's? I haven't opened mine up and would like to know what to expect if I open them up later to try any simple modding

Thanks!

Bump.

Or how much of a bass increase does this cause? 50%? Double?

Subscribed....for potential future reference.

To those that posted the technique and photos, 

damnit, i snapped off the copper and red colored wires while trying to rewrap the pads.. they were a b**** to put back on man. you guys think i can still solder them back on?

Just found this thread and I'm very excited. When I received my 780's it sounded like there was a piece that was loose and rattling throughout the left can. Not sure how that affects the sound but to me, the bass is entirely lacking. When I play music through these vs. my desk speakers or my (recently acquired) V-Moda M 80s, it sounds as if there is nearly zero bass at all. Definitely "punchy" but people describe is as "powerfully punchy" and "strong" and to me, it sounds exactly what my desk speakers sound like when the bass is disconnected. Even when I turn up the EQ it just sounds distorted at best and still entirely lacking. Could the loose piece (that seems to no longer be loose as it no longer rattles around) have affected the bass? I am looking forward to modding my 780's as soon as my friend (whom I lent them to) returns them to me next week and will report back as to whether or not it helps.

Have you tried opening up them yet? Just follow the pics and should be pretty easy. What you describe is not "normal" - lack of bass (on this cans) and the ratlling.
