The speakers should do well as they are. Cone/Spike Decoupling Gliders will very most likely improve the sound though, compared to using just the spikes alone. If the carpet is very thick and spongy, you might have a little more potential wobble than you would like because the Salon 2s are very tall with a narrow footprint; if so, Giant Cone/Spike Decoupling Gliders would be a better option (or Giant Fat Gliders without using the spikes at all).
