But I thought the locking casters would be cool, and would also help in
transmission loss... since the 5 casters only touch in small points on
the floor, less shock would get transmitted into the booth from a stomp
or footfall in another part of the building.
so basically, to caster or not to caster, that is the question... BRBR

Well, it may help you or it may hurt you, but you will also have a resonant
chamber under the platform when raised on the casters. I think it will be
pretty boomy with that air space under there.
