Do casters make a difference in sound?

It can. The cab will try to move in opposition to the cone motion. This motion can have an effect on low frequencies. One of the reasons for Hi-fi enthusiasts for using spikes. Though casters can reduce mechanical coupling with the floor. If you have casters, better if they lock. You can experiment. You can put the heaviest thing in the house on top of the cab (ask her first) and see if it makes a difference. If you don't notice a difference in the low end with and without casters, nothing to fix.
