It's likely 60 cm stands (about 2 feet) would almost certainly be for the consumer market, especially
if the stands have an upward tilt, suggesting intended floor placement. However, some smaller, short stands may be made for table/desktop placement.
As the OP notes, speakers should be about ear height for the midrange and tweeters. I have a pair of Event 20/20bas -- very heavy powered boxes (the specs say 30 lbs/13.6 kg apiece but my cognitive distortion would have put it at 35 or 40 lbs
) -- on top of a pair of composite stands. The stands were hollow square columns so I filled them with sand. I'm not too worried about losing bass 'traction' in this case.
While every force in Newtonian physics has a equal reaction in the opposite direction, we are talking about a cone and coil (the only pertinent moving parts) that weigh a few grams versus the far, far greater mass of the enclosure and any amps. We are talking about a ratio of probably several thousand to one.
It's my thinking that the movement of the cone/coil is of minimal significance in normal circumstances and operation.
