I have systems that are 3 dB down at 45 Hz, 24 Hz and 20 Hz, the latter augmented by a pair of powered subs that are 3 dB down at 16 Hz, which is well below what is audible (although it can certainly be felt). The latter are used only for video, not for normal audio listening.
I'd draw the line at 30 Hz for realistic reproduction of orchestral music, but I find the system with the highest roll off the best for listening to strings and unamplified music (ironically they take up the most space as they are electrostatic panels).
Do you miss much by not being able to go below 30 dB at a listenable volume? Probably not unless you are a video fan and have a system able to reproduce it all. And much of the time you aren't hearing the fundamental note but rather the higher harmonics anyway.
It is fun to sometimes put on some of the relatively few full size organ recordings with some content below 20 Hz but you can't really hear anything down there, you feel it, and may hear the overtones. Not a huge number of organs that can reproduce 16Hz anyway - 32 foot pipes take up a lot of space.
