1) The ultrasonic track is centered at 17.5kHz if I remember correctly, and then add some to the sides. So the needed frequency range is something like 16 kHz to 18 kHz. Or 15-20 to be sure.

Get the Frequencee app for your smartphone, or borrow someone else's phone, and play some tracks. You'll see how the speaker test works and you'll see where the ultrasonic audio lies.
