Metal with black finish. Very well made. They have (4) screw-in rubber feet per stand that can be used between stand and floor or between stand and speaker. I don't have the floor spikes, but they are easily purchased on Amazon or Ebay.
Top plate is 8" deep x 7" wide
Base is 12" deep x 9.5" wide
Mine have a few small marks, but still look presentable. Both are a little dusty, but should clean up nicely.
Asking $ 110 for the pair - OBO.
