May I suggest Fastenal for springs (or any number of other industrial suppliers). They have literally hundreds of options and they are dirt cheap. Many diameters, lengths, wire size, and very inexpensive. That let’s you much better match your component to the spring as opposed to a few limited options.
There is no right answer delkal, as it depends on your floor and speakers. Those claiming one answer is always right .... and like a broken clock. They are exactly right every once in a while.
Concrete floors and a speaker cabinet not as stiff as one would like, then odds are better to couple to the floor for damping. A springy floor and you likely want to decouple it, but not necessarily. If the cone is going one way, then the cabinet wants to go the other way.
Georgehifi makes a point about sorbathane. It is one of the best energy absorbing substances and absorbing energy you don’t want to turn into sound is a good thing (this is what sand does as well) ... and what the op is trying to accomplish with neoprene. I would suggest sorbathane instead, though more expensive. The 70D linked would be too dense as a set of 4 for almost any speaker. 50D which they appear to also sell or even 30 would be more appropriate.
