Anything above 20 KHz is, although the medical ultrasound systems operate with sounds up into the megahertz.
Almost all loudspeakers are designed with amplifying circuits, or output speakers, or both, that would not magnify sounds in the ultrasonic frequency (over 20 kHz).
Loud speakers can produce ultrasonic waves. But since the normal purpose of loud speakers is to produce sounds for people to hear, there is seldom a reason to produce sounds that people can't hear (other than to annoy certain animals).
