Whats the point of speaker stands?

[Macca]

Here's a thought - I wonder if a lot (most/all?) of the improvements reported from using speaker spikes is just that the speaker has been raised and there is an air gap between speaker and floor. Nothing to do with spikiness at all.

Almost certainly. I used some dice to raise a floorstander up off the carpet once, it was a change of sound and an improvement. All the coupling/decoupling business with spikes is classic bullshit baffles brains.
