On a concrete carpeted basement, springs (like Nobsound) would work better than spike, rubber (or silicone) cone/feet, granite, concrete slab, ...?
Nobsound springs (4 of them) support up to 40lbs, but I guess it is pretty limited. Most full range speakers will weigh more than 40 lbs.
I’ve never tried springs. I thought spikes work best. I might try springs on my subwoofer. It rattles too much on high volume.
[EDIT] I see that it supports up to 66 lbs (or 30 kgs). The would cover most mid size speakers.
