Looking for speaker base suggestions

I have a pair of black ATC SCM19A speakers, 68 lbs, which sit on a moderately deep shag living room carpet. The speakers came with long spikes but they sink into the carpet, such that the bottom doesn't clear all the way around. I'm looking for not so expensive, but reasonable looking ideas for a couple of bases for better isolation that raise the speakers, with or without the spikes, no more than 1"-2" and are roughly 14" square. Wood blocks that I could paint black are one idea. Isoacoustic stands, which I use under my desktop speakers, are neither very attractive nor low enough. Other ideas? A photo of the speakers is at  (http://atcloudspeakers.co.uk/hi-fi/loudspeakers/entry-series/scm19a/). Thanks,
