Yeah, not even close any more. Maybe 16 kHz.

I discovered another surprising thing a couple years ago when I made a big-ass horn-loaded subwoofer and was disappointed upon listening tests (with a sine-wave source) that it started to fade at 40 Hz and was inaudible below around 35 Hz. It was supposed to do better than that.

Sometime later, I got a nice reference calibrated microphone and used it with a free program (REW). Much to my surprise, I learned that the sub was indeed cranking out to 20 Hz (and a bit below, with rolloff), which remained inaudible to me.

Sometimes the problem is your ears (or between them).
