Put it on springs. Much better. Nobsound springs if you can only afford $30, or if you want the best then Townshend Pods or Bars. Pods are virtually as good but cost less and I think look better, as in you hardly see them.
The curling stone is maximizing vibration feeding into the floor, walls, and ceiling. Vibrations travel through all these setting the whole room ringing. A lot of what you think is bass response or room acoustics is really the sub exciting the walls turning them into speakers muddying the bass and everything else. Travels into all your components distorting them as well.
Springs eliminate all that, allowing the speaker to radiate into the room sound waves not sound waves plus mechanical vibrations. The improvement in clarity is not subtle, not if you go Townshend anyway. But even Nobsound will be a big improvement from what you are doing now.
