Well, that 125ASX2 was already relatively noisy in the audio band anyway...

I see lots of noise below 50khz. Any concerns for speakers that could go up to 45khz?
Yes but only if you are a bat listening to recordings of other bats

They can, but whereas we can clearly discern a 100hz difference plus minus 500hz we can't hear the same modulation at the same level at say 19khz plus minus 100hz.

Our ability to discern frequency modulation is inversely proportional to the fundamental frequency
