Aball, how do we know what our ears are capable of measuring if we can't measure their capability with instruments. What instruments are we using to measure the fact that we can't hear sounds at 40kHz?
If there is any effect from speakers systems 'moving' 0.1mm due to vibrations, that effect cannot be detected by the ear and in any case would be smaller than if your ear (the measurement device)moved a similar amount.
