WOW, that is INCREDIBLY helpful!!! Outstanding job, PS, thank you!!! Now we can start to compare the effects of various materials in there on the sound signature... AWESOME!!!
(Although I have to admit, seeing a knife blade next to that driver makes my manly parts shrivel a bit. Feels like it should be accompanied by a ransom letter or something).
You're welcome. It took me a while to figure out how to open these cans, as I couldn't find any info on that subject. All I could find was one photo of T5p open and that hinted me that this should be possible. The fit of the driver base in the cup was so tight that I couldn't see where one ends and the other begins (that tells you something about the precision). The use of knife may seem scary at first, but trust me: if yours are as tight as mine, you'll damage something using any other technique.
Hmm - maybe just pull it out with a magnet? I didn't think of this earlier, but even if I did, I'd still go with the knife. I don't like the idea of messing around carefully balanced magnetic field in the driver.
