Spikes or Spikeless

How heavy are your speakers? How thick is the padding and carpet? Have you tried your speakers with and without the spikes?

Spikes couple and allow vibrations to transfer. I realize that many theorize that spikes decouple by reducing the contact area between the bottom of the speaker and the floor. The reality is that the small contact point creates a very large psi value that in effect bolts the two components together. Vibrations travel very easily through spikes in both directions. Spikes are used with speakers to create a stiff, no rocking stance. All speakers are not the same so many times you have to try different things to find which works best for a given situation.

Mine is a tad different still. Just berber carpet glued to the concrete floor, no padding. My Paradigms need the spikes to sit solidly and they sound better with the spikes, no question. My Aerial 10t, with the Sound Anchor stands mind you, sound the same no matter if spikes are used or the heavy rubber feet. My horns are too big to care. In fact, the bass horns were designed to acoustically couple with the floor so they need to sit flat.
