Will you care? none of us can say. Will it technically degrade the sound? Absolutely. It will allow more motion of the entire speaker assembly, which modulates the transducer. An ideal speaker would have zero motion. Castors are wheels. With bearings. Which move.
Consider that some people go to the effort of placing speakers on spikes; and some manufacturers suggest that you fill the stands with shot.
In fact, if it were feasible, the way to overcome the castor problem would be with strategically placed mass so that the (lack of) resistance of the floor thorough the castor would not matter.
But if you need to move them regularly (say, out of the way for use of a living room and out for listening), then the benefit may greatly outweigh the loss.
Happy 4th.
