Hi sushi,

Ah, spoken like a true scientist. My only comment is that people hear what they expect to hear. . . If you put an acoustically transparent but visually opaque screen in front of two speakers, one on spikes, the other on rubber feet (or no feet), you'll hear, um, er, nothing or rather, no difference!

Spikes are fine for stability on a carpet.
