I got the Pedestales awhile back and am just trying to switch the rollers for spikes and I can’t get the roller off the insert. I think it is screwed into the insert that is mounted in the bottom of the speaker. The roller swivels and so it doesn’t unscrew from the insert. Anybody who owns a set of Pedestales faced this issue and solved it please let me know. I have tried to find the same insert so I could just remove the existing one with the roller attached and put a new insert in, and then screw the spikes into the new inserts, but I can’t seem to find the same exact insert online.
