I have used a variety of footers under speakers. The ones I got the best results from were Outriggers and the various Black Diamond Racing cones/pits.
Unfortunately, there is only so much that can be learned from reading about these kinds of products, since their effects on the sound are very system/room dependent. So, experimentation is the only real way to know. Good luck.
