How low can one hear Huh?? Say again

The reason subs work well is because at around 60hz your ear can no longer pick-up it's location with ease. At around 25hz in my room you can hardly hear the sub even though it still measures 80 db on the spl meter...you can feel the room begin to flex. At 20hz. and 70db output as measured with the spl meter you can not hear the bass at all...you can feel the room, cement floor and everything in the room begin to shudder at this very low freq.

A good test with sustained low bass freq is Archetribe (earthtones) which is " world " or newage type of music. Play it and feel your room, even if you can't hear it.

That is going to be an individual thing. Some of us can hear lower than others. The issue seems to be less about hearing and more about exeriencing.

We can still feel bass considerably lower than we can hear it. That is part and parcel of the aural experience of music.

Regardless of the listeners ability to hear, the system that cuts out above 30Hz robs the listeners of the sensation associated with their music.

Fooling around with a test disc I found (in watching the speaker cone move)a large dropout in my own hearing at about 20-25hz. I know it's there, but at that point it is out of my ears and into my belly.

Upper end I'm getting worse, it goes OK to about 12k and that's it. My son can hear to 16k. I understand the sound needs to be there to be full- but the tone escapes me...

Get a signal generator and start out at 30 Hz and go lower. You will soon stop hearing the signal, and it will be replaced by feeling it, including in your ears as pressure fluctuations.

I've just done exactly that: Fired up my modular synthesizer, plugged my headphones (5Hz-35kHz) straight into the low frequency oscilator (0.001Hz-500Hz)set it to sine wave and turned the frequency down. The result is a hum that goes lower and lower, past the well known mains hum and the pressure inside the headphones gets stronger.
But then there seems to be a transition phase at about 15-20, I'd guess, where the pressure rapidly diminishes and the hum turns into separate click noises! It doesn't sound like a sinewave at all anymore.
Yet when I use this signal as a modulator it turns out to be still a sinewave. So my guess is that we can hear tones below 15Hz but our brain interprets these as short burst of a tone with a much higher pitch.
Any other ideas?
