I was looking for information to see where crossover frequency and amplifier selection in a 2 or 3 way system is most important and came across this interesting article.
Audio Frequency Bands

If a tree falls in the forest and nobody hears it, does it still make a sound? Just because a microphone can't detect it, and a tape or LP can't record it, and speakers can't reproduce it, and your ears can't hear it, the bass fiddle and the symbols are still cranking out sound. I was at a high school orchestra concert and they had at least 5 bass fiddles. I could feel them play and it was a nice experience having them neutralize the too shrill violins, flutes, and trumpets. Sorry, off topic, but...
OG, a good precis of the article.

VH, indeed the body feels, the ears hear and the mind processes sound. Sight also has a role to play, as does life associations and mood - e.g. "Darling, they are playing OUR song".

I agree with Hilliard's "balanced" approach to the subject, that for the most natural reproduction, a system that is limited on one end of the spectrum should be equally limited on the other (as measured in octaves, not frequency). In other words, a playback that lacks sub-30Hz (for whatever reason) should also avoid anything over 15kHz (1/2 octave on either end).
Dear Zilch and I had several discussions on this. His mild obsession with "fixing" the HF of several stock Altecs that fell off at 14kHz (and he did it, bless his heart) ignored the fact that few of them played well below 40-50Hz. My contention was that he was "fixing" the wrong end, which I still believe. That ~1/2 octave of "air" (14,000 - 20,000Hz) while quite sizble as numbers go, is musically only the distance from F sharp to the nearest C, six tiny half steps that a small child can span with one hand.

I remember eavesdropping on Hilliard talking to somebody else...probably wasn't polite but I practically worshiped the guy...where he suggested the upper and lower 3 dB down points should equal 400,000 when multiplied....IE 20-20k. 40-10k, or for low fi 80-5k. Otherwise the system would be either low end or top end heavy...
Made sense to Young Guy.....

While we're on the subject, it's also worth understanding the difference between fundamental frequencies and first, second, third and fourth order harmonics;
