Rule of thumb. Not really true, but a good guess. My Nakamichi headphones
have as good bass as any subwoof I've heard, and I've heard a lot.

I'm talking about playing music from actual musical instruments, not
signal generators to produce the "brown sound".

The metric I use Al Stewart's "Roads to Moscow". At around 3:18 a bass comes
in, most systems can't reproduce it. It has to be a CD or some other digital
means, and LP with a sound that low would have the needle fly out of the 
groove. :-)
