Is There A Moveable Base To Easily Voice Speakers?

With larger speakers, especially with spikes, it is very difficult to effectively and easily move and dial-in a new set of speakers. Particularly if it's just one person. Get up. Sit down. Get up. Sit down.

Is there a device, or a special moveable base, or any method to easily dial-in and voice a new set of speakers? A dolly, a carousel, 2 pieces of plywood, etc? Thanks.
