Loudspeakers continue to be the weakest link
in the playback system by an order of magnitude and
more. It’s easy to understand why. Driver elements must combat startup inertia. Once in motion they fight
inertia again to stop, continuing to oscillate post signal.
It’s well known that distortion is proportional to diaphragm travel requirements. It’s also true that travel
requirements increase by a factor of 4 with each octave downward, so a speaker’s radiating surface area must
expand with wavelength to keep distortion low and
directivity uniform. Keep in mind the wavelength at 20 Hz is
1000 times greater than at 20kHz.
When a wavelength is greater than room dimensions,
reflections have little phase shift and rooms can reinforce
(pressurize) deepest bass frequencies in a beneficial way.
Without this help, most speakers would be practically
inaudible in the first octave.
However as loudspeakers radiate at slightly higher
frequencies the reflections are no longer in phase and
colorations due to errors in the time domain become very
significant. The multiple wavefront arrivals to the listener
provides an experience quite unlike the original source
material. Furthermore, these reflections cannot be
equalized conventionally without respect to the time domain without introducing further damage.
