You can hear 10hz. I play a tone generator when people come to hear my IB and everyone can clearly *hear* the difference between 10, 12, 14, 16, 18h and 20hz.http://www.geofex.com/effxfaq/distn101.htm
Quoting from that article,
"As you can see, the sine wave has been amplified a lot, then clipped off so that only the starting part of the sine wave remains. This has even more harmonics than the moderately clipped one. The result is a heavily buzzy sound."
So even if you clip 10hz, it will create more audible distortion harmonics and since the clipping is a total "flat top" rather than a softer type of clipping as you might get from analog gear, it will sound extremely harsh.
If you really want to listen to 10hz at high levels, use a tone generator
The fking Irene scene in Blackhawk Down has an 8hz fundamental at high levels, you can't get much deeper/louder than that. Even on my IB the 8hz part isn't that "audible" and the woofers are really moving.
