I FOund this chart I thought useful while looking for information on exactly what kinds of sounds we might want to hear that fall into the lowest audible octave.
Audible Frequency Spectrum
It helps to understand what one might be missing if a speaker is challenged below 40hz and whether or not it matters.
I'm sure there is other similar info out there as well that might help add additional insight.
In addition to the sounds listed that fall into the lowest audible octave, I would add that many electronically generated sounds from synthesizers and other modern electronic music sources commonly used in much modern pop music deliver output that can fall in this range. I find a lot of better quality modern pop recordings and remixes from teh last 10 years or so in particular sound best FWIW when the lowest octave is fully present.
