Those Motorola piezo superhorns are pretty flat out to 30 or 40KHz

There is no standard 8ohm speaker - so there is no answer to that question, as Bobs says, the super piezos go pretty high, although 60kHz is pushing your luck methinks. Silicon Chip magazine had a project called "bark buster" a few years ago that used these tweeters.

You might research transducers designed for ultrasonic cleaners.

Look at the specs for those transducers - they drop off pretty sharply either side of the 40kHz. You can get these from your local Altronics store.

So why 60kHz?

Philosophical question: is it still "sound" at 60kHz?

I suppose some bat's sonar detection is supposed to go to 100kHz but I'm not sure it's still sound/audio. The very word audio stems from audible and I rather think the intention may have been human audible.

Do different frequency sonar tone bursts penetrate thermal layers better than others?

If one is a rodent then yes.
Rodents use ultra-sound for communication to locate a mate and to avoid predators.
