Can too low of a frequency damage my speakers?

Distortion,distortion,distortion ! Common sense will go along way here.Overdriving and overdriving to distortion levels with any speaker is a crap shoot with it's voice coil.

Best advice ever but try explaining it to someone. Telling them "its when the sound starts to distort" does not always sink in and especially with younger people and their music. Most of them seem to strive for it with their booming car audio systems.
