All that unwanted movement can colour and distort the sound. We do our best to prevent vibrations by adding bracing to the cabinet, but that doesn’t really help with the movement.
The HMS Series is considered to be Audiophile level by many and incorporates a significant increase in mass loading capacity and designed with very high quality speakers in mind such ProAc and other premium manufactures.
Furthermore, in accordance with Newton’s third law of motion (each action has an equal and opposite reaction), whenever the speaker cone moves in one direction it will try to push the speaker cabinet the other way.
The theory is that the mass and spring characteristics are chosen so that the resonant frequency of the combination is well below that of any frequency they’re likely to be asked to isolate. For example, if the lowest note a speaker can reproduce is 30Hz, then the resonant frequency of the supporting platform needs to be well below that — perhaps just a few Hertz or less.
