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?

Suteetat,

Personally, i find on the majority of my recordings that there is information below 40hz...whether one would care or not is another matter. I find having a sub with a 48db cutoff of anything ABOVE 40hz and the sub continues to work quite a lot during rock bands, electronic (obviously) but even orchestral. Is it 'essential' like midrange? no...but in the overall fullness of sound, i find the sub an integral part of my system i would not do without, and i run Wilson X1/Grand Slamms.

When the kick drums kicks, you can feel the air pressurize. I am not sure that is 'musical information' per se...but it sure feels like an integral part of the experience to me. So does low level info that i often hear within the recording room down at that level on some of my albums.

BTW, i just learned the Bosendorfer piano goes down to 28hz??
