I just purchased a used set of lsi 25's and they did not come with carpet spikes. I called polk and they gave me the number to the Canadian rep. The Canadian rep says they aren't available anymore. I have checked on parts express, and am not sure what type of thread they use. hoping someone can lead me in the right direction. Or maybe polk can step in and send me some spikes :D
they are a little tippy on my carpet.
