Clearthinker— Mc is always wrong. Instead of asking questions about the floor, the speaker, or is a sub, he just blurts out garbage.
It all depends on the flooring and what does the speaker manufacturer recommends. For Tekton speakers, springs or spikes won’t make any difference, but ask Magico what they recommend and you will get the m-pod choice which works great for their speakers. Same goes for Wilson and others. Me, I would look at Isoacoustic pods for the speakers if on a plywood/joist floor or spikes on a carpet/concrete floor
