I've not raised them off the floor, not sure they'd need that, although a very rigid and massive stand to clamp them to would be terrific, I'm sure..............I have replaced the fuse with a coiled up silver wire, and the other tweeter bar with wire (I had been using several "bypassed" resistors, but once I got my room dialed in, found that the tweeter didn't need padding down after all). I've recently gotten the Vampire spade to banana adaptors, which work well for cables that don't already have banana connectors.
