Does a Subwoofer Make Spiking Redundant?


I just added a REL T5/x to my system, and a question rises up from the depths of my ignorance: Does a subwoofer do the thing spiking speakers is supposed to do? Does a subwoofer make spikes redundant, or do they work at cross-purposes? If it's relevant, I've got the spikes on Herbie's Audio Lab puckies, on a (thinly) carpeted floor.

"Does a subwoofer do the thing spiking speakers is supposed to do?"
Are you asking if it is worthwhile to spike subwoofers? If so, according to many who use them, it is a good thing. I think you're just asking the question wrong. Spiking and subwoofers are obviously two different things. 
Not the subwoofer, the main speakers. Or rather, the main speakers were spiked before I got the subwoofer. If it's true that they're two different things then that's the answer to the question. 
Never use spikes. Use springs like Nobsound, or even better Townshend Pods or Bars. Or the very best, Podiums. I’ve compared and Townshend are by far the best. Spikes, the worst.
