How do you move HEAVY speakers with sharp spikes without lifting?


I have large (175 pounds each) speakers with sharp spikes placed on carpet. I would like to be able to move them a few feet by myself to tweak their positions but lifting them is obviously not an option (I can't even lift half their weight).

I currently use a convoluted method involving tilting them over about 30 degrees, slide a board under spikes on one side, and then repeat on the other side. The speakers almost toppled over the other day which would damage them.

I'm aware there are non-spike alternatives but do not have the money to spend on these options. Any clever moving methods out there? 

Thanks!

The method to move such speakers (which works provided they are not the very tall, thin and fragile spikes) is to "walk" the speaker. You lift three spikes off the ground and pivot around the remaining spike, moving only a few inches at a time, repeat until you are where you want. This works fine on carpet but will leave marks on wooden floors if that bothers you

Alternatively invest in some furniture gliders from a hardware store to put under each spike and move it then tilt to remove the gliders
I bought some Herbie’s Gliders to go under the spikes and protect my wood floors. They aren’t expensive and work well.

Yup...I had to do that with mine.   Go to Home Depot and get "SuperSliders"...  they come in a package of 4.   There is one kind for hardwood flooring, and another for carpet.  Put these under the spikes of the speaker....I would put protection between the spike and the slider.  Move the speakers slowly and carefully, but you will be amazed and how easily this is accomplished....(a little grunt, but very doable)
