What is "deep extended bass"?

The most common definition I've seen through the years is:
1st octave, 20-40 Hz, low bass
2nd octave, 40-80 Hz, mid bass
3rd octave, 80-160 Hz, upper bass

Therefore, listening to an acoustic string bass (42 Hz common tuning for the open E string) is actually mid bass and above. True low bass is the realm of bass drum, organ, synthesizer, occasional piano, etc.

Not that many speakers/rooms will produce +/- 2dB below 40 HZ. Manufacturer's specs are often optimistic in this regard. A friend recently went through the exercise of optimizing his sub-woofers in his acoustically designed room using a real time analyzer. Low bass variations of +/- 5 to 10dB were not uncommon and sometimes position change (of the analyzer) of only a few inches altered the bass response reading by several dB.

Even for those fortunate to own speakers/rooms with reasonably flat response below 40Hz, how much meaningful music software is available with information in this range?

For all this, I agree with tubes that listening to a well recorded string bass can be a real pleasure. And, as I said below, a speaker with a response to at least 40 Hz is basic for me.
