Hmm, Newton said something about every force creating an opposite force...
A washing machine on spikes would wobble out of the house.
Itïs easy to test. Put your fingers gently against the speaker to feel it resonate. Now switch from spikes to damping feet and do the same. The diffrence is huge.
When listening you will notice the bass tighten up and your neighbours will thank you. Because the whole construction of the house is not playing along with the music.
No need for further discussing. If you want to know the physics about it there is plenty on the net.
If your speakers sound better on spikes, then great. Thatïs whatïs most important.
Maybe, but you won't hear much detail from your speakers as they are flapping about in time with the music (3rd law remember). To be positive, your post does raise the point that the way the room interacts with your system is critical. Ideally, you live in infinitely rigid box, with decor appropriate to the design of the speaker. In some ways, if you have a suspended floor, then you will never truly hear what your system is capable of, because either the driver can operate properly (set up as you prescribe) or your floor gets overly excited and colours the sound. Like most things, real world is about compromise.
Actually a speaker placed on damping feet will move less. Thatïs the whole idea. Itïs not the bass driver on the speakers that causes the largest movement, (even though it is the source) it is when the speaker and floor starts to resonate. It will resonate on damping feet as well, but at a very low frequency.
Now if you push the speaker with your hand, it will sway. But thatïs not relevant here.
