...and I should also add that my measurements on 5 Harmony acoustics aren't
scientifically sufficient to conclude that *all* Harmony acoustics are
bass-deficient. My guess, however, is that Steven most likely boosted the
level of the first harmonic of the string bass, thereby giving the
impression of more realistic sound. That, plus the contextual (i.e. expected
acoustical response by the listener) filtering we are so adept at employing
probably resulted in a satisfying experience. What 's usually missing is the
"floor" of these instruments (i.e. the fundamental), without the sound still
remains distant from reality. Finding and amplifying this floor for the
brass bass on the aforementioned Coon-Sanders Nighthawks recordings
immediately brings life and a sense of reality to the sound. However, if
bass data are not present on a recording, then no amount of restoration will
improve that part of the spectrum.
