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.
