I thought I'd post some pictures of a few potentially useful modifications I've made to both the 570s and the 550p subwoofers.
SVS makes these dandy upgraded subwoofer isolation feet (SoundPath) that work to replace most any stock speaker feet. The 570 towers are a little too short in placing the compression driver at seated ear level. I modified these feet to give me another 2+ inches of lift. The down-side is that the 570s are pretty tippy due to the weight of the speaker drivers loading the front baffle, and the fact that the front feet are recessed too far back. I've also included a photo of my California earthquake (or small child) remedy--this is a hook screwed directly into the subfloor with a bungee attachment to the speaker feet. The SVS feet are definitely not the best solution for stability on carpeted floors (the spikes probably are), but for those of you with hardwood floors this will be a BIG improvement over the stock feet.
Without starting too much of a war over the merits (or lack thereof) of decoupling the speakers from the room, I can say that I’ve eliminated some pretty annoying resonances with these feet (fact). I have room treatments on the way that I hope will address a few other annoyances. Not fact, purely subjective: It may be the placebo effect but I think I’m enjoying tighter bass as a result of the isolation feet compared to the spikes. Wife and kids make a double-blind test impossible, so you can take that with a grain or two of salt :-)
Again, for some of you with hardwood floors, this may be an interesting option.
