I'd like to say how impressive the measurements of the thunderpants looked from Can-jam.
Even more impressive considering they were tuned by ear. Nice work!
 

Oh, that's right! Did anyone have a record of it that they can post? I'd love to see some measurement charts, if anyone has them.

I must say I expected nothing less from our master craftsman.

Haha, I asked my question before doing any looking. I promptly found it, and had to immediately go get a towel to wipe up the drool. It was cool to see the measurements on the thunderpants, and some of the high-end Sonys.

Holy crap! That second pair of Thunderpants has some serious high frequency extension. Which plastic and wood is used on that one?!

They were Colins with brown ebony cups and MDF baffles I believe, though it's hard to keep track as I keep changing the design with every pair.

The swt pair definitely looks more sorted out and in line with what I would prefer. The two are very close actually, but that peak in the midrange worries me a bit. 
 
That 6-7kHz peak seem inherent to the driver or the implementation and Don has clearly tamed it to the best of his abilities. 
 
This was the thing that wualta also found objectionable in my TPs when it came around to him. It is there just like it is on swt's pair but looks like it is very hard to get past that.
 
I am however impressed with the low freq extension on Colin's pair, not that steve's pair is too far behind.
 
I do wonder why there is the change in isolation though after 3kHz. It seems to drop off completely on Colin's pair while it looks like there is some leakage in the high frequencies after 8kHz on swt's..kinda weird since they are both using same earpads.

confused me as well... no idea what's going on there

Thinking of using a fake ESW9 for housing? For your consideration:

After looking at some close up of these fakes, I'm not so sure if I want to use them as fosterphone housing anymore.

I think the point is to get the headband and turn your own cups.
 

 

[ujamerstand]

Yeah, but look closely at the headband though, on the edges there are bits of plastic hanging off, they don't fit really well together, and they also look like they WILL fall apart on you in no time. I want to make a pair of closed SFIs for portable use, so build quality is kinda important for me. If they at least LOOK better built than what I've seen, maybe I'd buy a pair.

Colin changed to the Transpore/Micropore cross and a different felt dampening.  He also plugged one of his ports.
 
WRT the fake ESW9s, they are only used for the frame.  The plastic cup will be usable with bitumen, dynamat or other dampening on the back, but I do plan to make my own wood cups.  There are three or so knock-offs.  Two are ok, one is great.  I'm trying to get the source of the great ones, but they were $35 each in quantities of 25 or 50.  I could get a single evaluation pair for $40 IIRC.

Mind sharing where please?

Supposedly, the newer fake ESW9's have a much better build quality that makes them nearly indistinguishable (at least visually) from the real thing.
