best way to save my wood floor


What is the best way to protect my wood floor from the speaker spikes. I have been using the sound anchor coasters. They are great, but too high off the ground. I have also used pennies, but they are too soft and spike can still get through.
what is thin and sound good? Thanks in advance.

I don't mean to be a "punk" or anything like that but what are the spikes for? The reason we're using them for is to help stable the speakers? release the un~wanted vibration energy to the floor? If you're try to put something(moveable?) under it I don't think you'll need to use spike?!?!? .02, Rute.
Those low profile cups used w/ Audio Points: can't be much taller than 1/8" maybe less. These are the FastPoints available from AudioNut in Phoenix. Set of three FPPD's are list $21, they sell them for $18. (877)944-5505. The cups that come with BBC cones are also very low-profile; I use them under my speakers & including the BBC MK2 cones the whole thing raises only about 3/4".
