Plato and others with heavy speakers,
You might find a dolly to be a very worthwhile investment. I bought one and padded it with round foam pipe insulation wrapped with duct tape, and many layers of duct tape on the flat bottom part that goes under the speaker.
For really really big speakers, an appliance dolly is called for. That's one with the strap that you can tighten to hold the speaker in place.
