    The human ear can detect bass well under 20 Hz, given that the volume is high enough. I've been able to detect a 15 Hz sine wave firing out of my SVS. It caused a lot of pressure in my ears (akin to descending under water), but it was beautiful. Extremely low bass can also add that little bit of unnerving energy to soundtracks. As J Fo said, the reason the Haunting is so revered is because of how downright scary some of the low bass impacts are. Titan A.E. has an especially memorable instance of pure subsonic bass that can't be heard at all, but only felt (granted that your in the right room): right after the two huge ice crystals encompass Kale and Akima's ship, an extremely low rumble is *felt* for just a second or two before the bass shifts back up into the audible frequencies. It's extremely impressive, and ominous as hell.

    I have to agree with those who say 3Hz is more like nonsense in a sub.
    In fact you can tick your fingers as fast as 3 times/sec on the table to make a ticking sound (I can), or click your tongue that fast: it has nothing to do whatsoever with audio (or your ears).

    Anyone who thinks he "heard" a note below 15Hz has to make sure first he didn't hear it's harmonics. The ear just stops at about 16Hz (different for different people). And below 10Hz, as said, the different "waves" start to become separatedly audible, more like a rattle - which is quite something else than an audible 10Hz, or lower, tone!

    And, BTW, most amplifiers won't go lower than 10-20Hz either, so even if the sub channel would go as low as 3Hz (it doesn't), it wouldn't come out.

    Also, perhaps it's not actually that really deep 15hz sound you're hearing, but the distortion caused by the subwoofer.

    Cheers,
