Helmholtz resonators and tube resonators are very different. A Helmholtz
resonator will isolate a single partial (there may also be a frequency related
to the neck of the resonator, but this is normally inconsequential), while tube
resonators are harmonic.

True, but there's not a huge difference when an inharmonic
timbre is used -- the frequencies corresponding to the overtones
of the resonator will die away quickly after the initial strike (in an
exponential decay with time constant on the order of the length of
the tube divided by the speed of sound), leaving only the
fundamental, and any near-harmonic partials, to continue to
resonate . . .
