Several speakers and (very sadly) several cats ago, I had a pair of MG-1s. For a couple of weeks after setting them up, I sprayed a bunch of rags pretty heavily with the stuff that supposedly smells repellent to cats (can't remember the brand name), and used them to surround the bases of the speakers. For those weeks, the house looked a bit like an early scene from Close Encounters of the Third Kind, but I ended up never having to spray the speakers themselves, and the cats stayed away from them for years, despite their fondness for demonstrating creative woodworking and upholstery skills on the rest of our furniture.
