just play some movie or some music at a loud level and, with your hand, touch lightly the sides of your main front speakers (mine are M80s) and you'll very easily feel the vibrations;
vibrations usually translate as sound and that is why cabinets are braced (sometimes heavily) to keep the sound clean, uncorrupted by cabinet vibrations. cabinet vibrations translate as distortion.

one usually can have quite a good idea of the amount of bracing in a speaker cabinet by listening to the sound when you hit it with your knuckles. ideally, it should be "dead".
