frequency range for instrument vs speaker


http://www.independentrecording.net/irn/resources/freqchart/main_display.htm

After seeing this link in another thread, I wonder about this. Let say that you don't listen to any classical instrument/music, normal rock and pop with no heavy synthetizer, just drum, guitar, etc, it seems that there isn't really any need for speakers that go much below 40Hz, considering that the lowest instrument, the kick drum (I assume it is the same thing as bass drum?) only go down to 50Hz.
Certainly listening to this type of music via speaker that go down flat to 40Hz vs 20Hz, bottom end is certainly quite different but I am not sure what is it that I hear in the subbass area (according to the chart) that is not suppose to be there, at least according to the instrument's frequency? Does drum give out something lower than its fundamental?

My Vandersteen 5A's have a bunch of pots in the back that adjusts frequencys from the very low bass to the midbass. Richard himself helped me with my setup and told me that the goal was NOT to get a flat frequency response...just s pleasing one. Flat frequency response is a-musical.
