Say, Doc, these what your DJ100s look like on the inside?

I remember exactly how the insides of the DJ100 look, but I popped it open just to be safe.
The holes surrounding the driver on the outside are in the same pattern.
I noticed what appears to be two extra large holes inside the cup. It's hard to tell if these are really holes or not, but it looks like it.
I also noticed what also looks like another hole that's not there on the DJ100. I can't tell if it's a hole or not, but I've circled all of them in the picture below. If these are all not really holes (hard to tell) then they appear to be both the same. I take it the inside of the cup is hard plastic? It almost looked like a different material.
Based on the mods I've tried, every little internal change makes a fairly big difference in the sound. It seems if you cram too much material in there behind the driver, the sound quality would degrade.
I ended up using none on my DJ100. It's possible to make it go from anywhere from extremely bass heavy to making the mids excessively forward. So much that it's fatiguing super fast.
If you want, I can send over my Mogami W2893 recabled DJ100 with M50 pads. It has hundreds of hours of burn-in probably.
With that graph I'm surprised there wasn't a huge upper mids peak somewhere. Past 1000hz it looks like everything fell off a cliff. Maybe I'm reading it wrong.
What's funny is that up to 1000hz the graphs looks similar to the M50. Past that it's almost looks like the 272HD graph maybe if I remember right.
Maybe they added some extra treble on the Tony Bennett, but highly unlikely. Despite the forward mids, my DJ100 is very non-fatiguing and as close to being as smooth sounding as the HD-598.
This is coming from a guy who found the SR-80 too fatiguing (but the SR-225i is Ok, strangely enough).
If the DJ100 lacks anything, it's in the treble somewhat. M50 pads seem to increase this a little. At least it sounds like it! I've noticed if you use SRH-840 pads, the DJ100 becomes extremely fatiguing fast. Too much air/room inside the pads and the sound gets worse. With the M50 pads, the mids are more balanced out and a tiny bit less forward.
