How low is a piano?

I’ve heard that the open low string on a upright bass is about 42hz. Does anyone know where the lowest notes on a piano fall

I got this,...

My Steinway grand piano is 28 1/8" high from the floor to the top of the white keys.  It will not go any lower, therefore, 28 1/8" is the lowest. 

Don't have a Sawsall?

Depends on the piano and the tune.

this may help in the general question of what falls into what audible frequencies

Is this for regular people, or furries?

I have a DVD of Ray Bryant playing a monster Bosendorfer. video old, scared me, but the sound is AWESOME, whoever recorded that, used 3 mikes along the length of it I seem to remember.

Ray is terrific, I had no idea, inherited it with all the LP's from my friend Roderick.

About 40” 😉.  The lowest note on a Bosendorfer Imperial is (CCC) 16.5 hz.

According to this link, about 27.5 Hz.
