Speakers On Wheels?

get advice from caster specialists

make sure you can return them, until you get the right size/type that works for you.

if sized right, they stay put, until you push hard enough to get them moving. no brake required if sized right.

believe me, you want 3, not 4, more weight per wheel and roll them anywhere no shimming or wobble. add anti-tip corner blocks if needed.

hard floor material: soft wheels

soft floor material: harder wheels may be needed.

mine came with my JSE model 2's

caster central

IF you use a plant stand/dolly, I still recommend modifying for 3 wheels, so look at the bottom frame: something solid underneath, across the back edge to mount a rear center wheel? then solid corners for two anti-tipping blocks?

@bondmanp Funny, two nights ago I was dreaming about a piano mover bringing my speaker through the window. It may have been raining. But no, I’ll have to recruit a friend to help me bring them up the stairs on a hand truck.
@elliottbnewcombjr I would have thought four wheels are better than three. I still don’t understand why four wheels would create a problem. Anyway, I can put these dolly’s together myself so customization won’t be an issue.

If your floor is perfectly level, four wheels should be fine.  If not, three gives you a better shot at your speakers being stable.

I don't know how heavy your speakers are, but in my experience, if you are going to make a dolly of your own, just be sure to correctly size the casters so they are robust and can easily take the load.  Years ago I built a stereo component rack using stained shelves with threaded rods on casters and "cheapened out" on the casters.  Needless to say, I found myself having to replace them with ones more suited to the task. Avoid the headache and do it right the first time.
