With all due respect I suspect that you have no practical technical
experience with subwoofers capable of 120+ dB @ 10 Hz with low
distortion.

Certainly true in my case.

Look at the Fletcher Munson curves and reasonably extrapolate them to 10
Hz. Note what the approximate threshold of hearing is at 10 Hz.

True enough. However I'm wondering how often this is needed for music. I
can see that some organ notes may require high levels below 20Hz, and
perhaps some special cases like thwacks on big drums. But beyond that is
it
more likely to be a 'requirement' for the bangs and thuds of film
soundtracks than mere music? The lowest bass guitar notes I know of
off-hand is at about 30-35Hz IIRC on a Little Feat album.

Not just Little Feat, Jim.

A five-string bas guitar with standard tuning has the lowest note
B(0) at 30.8Hz. Such instruments are not particularly common.

On the four string bass guitar, standard tuning, the lowest note E(1) is
41.2Hz.

Of the instruments of the orchestra, the harp has the lowest range.
Most orchestral harps with the exception of cross -strung instruments
are tuned diatonically with the lowest note at C(0) 32.7 Hz


So I wonder what type of music Arny can be referring to.
