DIY! Get some "fender" washers from any hardware store. These are like regular washers, only with much smaller holes. Get enough of them so when stacked (and glued together with JB Weld) each spike sits in the hole but does not touch the floor. The spikes may settle in slightly so use one more than you think you need. I pimped mine out completely by spray painting them black to match my spikes and speakers.
New Soliloquys with spikes and hardwood floors
I'm a newbie so don't laugh. I just bought a pair of 5.3's and at 80lbs apiece, how do I keep them from burrowing into my livingroom floor?! On hardwood floors, should I use the spikes or something else to isolate them? Any help would be appreciated! Thanks, Mike.
