My system is on the second floor. I added some of the mentioned Nobsound springs to subwoofers and noticed my kitchen lights (one floor bellow) don't rattle as much. However, I feel as though my subs lost some punch.
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.
