The method to move such speakers (which works provided they are not the very tall, thin and fragile spikes) is to "walk" the speaker. You lift three spikes off the ground and pivot around the remaining spike, moving only a few inches at a time, repeat until you are where you want. This works fine on carpet but will leave marks on wooden floors if that bothers you
Alternatively invest in some furniture gliders from a hardware store to put under each spike and move it then tilt to remove the gliders
