I don't know if its worth the time to cut the free carpet to size or not. Probably not.
I'll bet that if you played sine sweeps through your sub you'd find that at one or more frequencies the sub rattles around on the Travertine floor on those spikes. It might even dance!
Rubber feet from a home improvement or hardware store will address that.
There is a good chance that your room is overly reflective and needs acoustic treatment.
