Thx guys. It seems that it's not for pro audio use. Right?

It's for ultra pro audio use

So we know it goes up into the ultrasonics, but it would be interesting to know how low it (also) goes

It wouldn't be - believe me
Ultrasonic transducers - any type - aren't completely usable in audio frequency range which interest us all here.

Typically they cover the range 10 kHz - 150 kHz

Depending on the type and application.
There are various type starting from piezoelectric and magnetostrictive as basic.
