Evan,
I have a similar problem whereby my large speakers (Avantgarde Duos) have to be moved forward from the back wall every time I listen to music. The solution I settled on was furniture "Sliders" I placed under my speakers. They are 1/2 thick and round, come in various sizes and have a sticky side that is placed against the bottom of the piece of furniture. They are teflon coated and easily glide over all surfaces including carpet. I bought them at Home Depot-- very cheap. No drilling into the speaker or otherwise permanent damage is necesary. Enjoy listening.
