Good question, Mapman. AFAIK, the casters are affixed to the plinth base, so you get both. I asked Jay if the plinths sat flat on the floor, since my basement floor (carpeted) is not completely flat. His response was that they come with casters, so an uneven floor shouldn't be an issue. I guess I'll find out when the speakers arrive.
Question for Ohm Walsh owners: Do the Ohm Walsh speakers require a perfectly level horizontal set-up to sound their best? I know other speaker manufacturers are adamant on this point, but perhaps, because of the Walsh design, horizontal leveling is less critical?
