I have read many threads on the compression drivers like the recent "4344MKII and 275ND problem" and ones on how you should not test there ploarity with a battery etc. I really don't get how these things work and no way am I game enough to pull mine apart to have a peek.

I understand they have a diaphram; like a mini speaker cone right??? and that makes the sound ??? but what is the 'plug' I read about and how does it fit into the picture? Why is there not a correlation of polarity to forward movement of the diaphram (like mentioned in normal speaker datasheets)?

Any exploded views of a driver around or someone post a pic of the innards???

Finally the 2405H seems to be a 'normal' speaker as they mention in the datasheet that positive to black gives forward montion. So why is this, which works at even higher frequencies, seem to revert to 'normal' speaker technologies that I do understand.
