You make a good point, although you should keep in mind that there 
aren't too many pieces of analog equipment (and I'm talking physical 
things like mics, speakers, and even cables) that can really fully 
transmit frequencies above about 60khz, so 192k might be a little 
overkill.  :)

Also, don't forget that it's possible for two frequencies within a 
given range limit to produce frequencies outside it, and vice versa. 
Frequency intermodulation causes additive and subtractive frequencies 
to appear.  So it's entirely possible that this could be a part of 
what you're hearing.

Sweet!  I just saw a photo in one of the typical musical rags last 
month, where a studio had constructed a kick drum mic out of an old 
woofer from an NS-10.  Let us know how well it works!
