Heavy difficult to move speakers- how do you deal?

Really terrific ideas.

Speaks to a serious need for speaker manufactures to consider what people are having to go through and offer solutions in line with how they've created their speaker feet.

Townshend Audio Seismic Podiums do an amazing job of cutting the transmission of vibration between speakers, floor and your system. Difference in my system compared to casters was startling (200+ lb speakers).

Because the isolating springs are in housings above the rubber feet you can put sliders under the feet with no harm to sound quality.

I have a pair of Paragon Acoustics Regents. I am not sure how much they weigh. I have heard 150lbs, to 185lbs. These are lead lined and very heavy. I move mine with a cloth covering them with a furniture dolly for more than 10ft. I use furniture sliders for less than 10ft.

On most our heavy speakers castors are built into the stands, one you have the desired location, spikes on outriggers lift the speaker off the castors.  https://pbnaudio.com/mr-777/
