@buellrider97 , Appreciate the comments, at least music and wine are legal vices!
The sliders are nothing special. I just ordered a round set off Amazon that had a diameter just slightly larger than the podium feet. The feet are just sitting on them. The weight and lip on the slider keep them in place when moving the speakers.
It will be obvious but make sure you move the speakers around by pushing on the podiums, not the speakers. If your speakers are tall it helps to have another set of hands to steady them when moving.
One other suggestion, if you don't have a simple bubble level you might want to pick one up on Amazon as well. Don't need anything special but for a few bucks it is very helpful for leveling the speakers on the podiums.
Hope everything works out great for you...
