When we say that for example 50Hz is not locatable, I think it's important to realize what 50Hz is:
A continuous and pure sine wave with 50 cycles per second. nothing else.
Everything that differs from that is not solely 50Hz anymore, but a wide sprectrum, that can cover the whole audible bandwidth and beyond, depending on how much it differs from a pure sine wave. "Air blast"*, pop, transients, asymmetry, all that means that there's more frequencies involved than the fundamental frequency. And those higher frequencies can of course be locatable. But a subwoofer is not responsible for reproducing them.

*(I guess what you mean by "air blast" would be subsonic/infrasonic, therefore filtered by the recording/mixing person, or if not, it won't be reproduced by most speakers anyway)
