I posted a few months ago about putting shims (quarters) under the front of my M60s because they were leaning forward. Well, they're doing it again. I realized the cause is all of the weight being on the front of the speakers. The forward weight is compressing my carpeting/padding more on the front legs than the back. I would think spikes would rectify this, no? (Of course, I went to look for them on the web site and I can't find them. Did Axiom stop selling them?)
