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!

I use a four 18"-long 2 x 2s to move my Vandersteen Treo CTs (≅ 65 lb each). I rock each speaker back enough to slide one 2 x 2 under the front, and forward enough to slide another under the back. You move them by (very carefully) pulling each pair of 2 x 2s in the intended direction. This has worked for me on a rug and an bare floors.
+1 Herbies gliders. My speakers are 220lb.s apiece w/spikes and i move them anytime no problem ....on wood floors.He can tell you if they will work on wood floors.
Use ceramic tiles, tip the speaker over just enough to insert one tile underneath the two lifted spikes, repeat the procedure for the other two spikes, and the speaker can be moved on top of ceramic tiles to make the -fine- adjustments. After that just remove the ceramic tiles by reversing the procedure. 
Here is the real question is why you would want to?

Normal setup protocall is to move the speakers without spikes, you can use carpet sliders or felt pads to slide the speakers on carpet or hardwood.

Then once you have located the correct position, apply blue painters tape to outline the speakers flnal position, then carefully lower the speaker on its side and reinstall the spikes, level and done.
