Heavy difficult to move speakers- how do you deal?

Many people here have spoken highly of these Herbies Gliders.  Not only do they make it easy to move speakers, several have experienced significant performance improvements and they’re relatively cheap.  Win win win.  Hope this helps.

I use a hand truck with a blanket to protect the finish and it works really well.

Can you put casters on Sonos faber speakers? amati g5

I am an advocate of alternate positions, alternate toe-ins, especially related to Imaging for one or two listeners.

I move mine frequently

Furniture Type Dual Wheel Caster's Axels are firm, single wheel axels, even high quality, wobble. 

3 (not 4) Casters. will always be steady, no shims needed anywhere you move them. More downward weight (+33%) per caster.

An apron/skirt (my current speakers shown below) concealing the casters automatically prevents tipping.

Rear Anti-Tip blocks. 2 casters up front, 1 rear center caster, no apron/skirt: you need to prevent tipping.

Put 'anti-tip' blocks in the rear corners, just a little shorter in height than the casters, they only touch the floor if the speaker starts to tip. 

Lastly, tilt: aim the tweeters at seated ear height (see the unfinished pine 2x4 above my front casters, lifts the front 1-1/2". The upward tilt also alters the angle of reflection off the floor and ceiling
