Is There A Moveable Base To Easily Voice Speakers?

On carpet, one way I've found works really well: set the speaker (without the spikes of course) on a heavy piece of fabric (like a canvas drop cloth) which extends all around the base of the speaker abour 4 feet or so. It's then quite easy to pull cloth (and the speaker) across the rug in any direction.

On hard floors, you can place a (3' x 3' or so) piece of carpet sample upside down under the speaker and slide it around easily.

One of my audiophile fantasies is to have my speakers move by remote control. Imagine being able to adjust, in tiny increments, forward and backward, side to side, and toe-in. With precise coordinates captured at all times.

On carpet, put the speaker on a piece of MDF cut to fit inside a baking pan. Works for even the heaviest speakers.

How about not putting on the spikes at all, dialing in the speakers, and putting tape in front of the two corners of the speaker?
