I have uploaded a sample of a track which contains heavy bass. I want to know how low it is. All I see is the woofer moving. I've never heard or felt this reproduced on a subwoofer so I wonder how low it is?

I don't have a way to measure how low something is (other than comparing it on a piano which won't work if you can't hear it).
However, I wanted to point out that "back in the day" it was common to see a woofer jumping around without sound when playing LP's because of rumble. My integrated amp had a 16 Hz subsonic filter so I could save my speaker and amp the trouble of attempting to reproduce this noise.

I don't know what the source of this clip is or what speakers you are reproducing it on, but since your woofer is moving but you cannot hear it, it is probably subsonic. It may be that on a good sub you might feel some impact from it.
