Human hearing below 20Hz is described in this paper:
Hearing at low and infrasonic frequencies Moller H, Pedersen C S - Noise Health
Good site with audio tests including subs:
(this direct link also tells when you are hearing sub overtones- not good)
Low Frequency Harmonic Distortion Subwoofer Sound Test
In the end there is the human. For me a system reproducing music is sufficient
with 30Hz at -3dB. For electronic and movie sound effects the rotary sub might
be useful ;)

PS. I stood once next to a 16Hz organ pipe and all I could experience was wind.
