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?

I seem to recall that a typical electric bass guitar drops to mid to high 30's on the open low string. For some reason 38 is sticking out in my mind. lots of fronts will do that but the discussion on spl above my explain why the sub helps out.
