The reason there isn't much scientific research about this kind of thing is because our measurement equipment isn't as good as our ears. Maybe in the future we will have test gear that will be able to measure more subtle effects that right now are only detected by humans.
Spikes versus Rubber on wood floor?
I am awaiting a pair of new babies, the Von Schweikert VR4SR speakers. They will be positioned on a wood floor over trusses. Anyone have an idea if spikes or some rubber isoproduct will give me a better sound? Any brands of either that you would recommend? Thanks.
