Spikes or rubber feet.

I've got a nice pair of tower speakers that are new to me. They weigh 65 pounds each. They sit on hardwood floors. Currently they have hard rubber feet that screw into the bases. They also came with spikes. Spikes are a no-go for the hardwood floors but the spikes also come with metal disks that sit on the floor and that spikes sit on. There is a cone shaped dimple in the disk that the spike fits into.

Is there likely to be any appreciable benefit to the spikes sitting on disks compared to the hard rubber feet? They are obviously easier to move around with the rubber feet.
