I own the Auralex Subdude which raises and decouples subs from the floor. I can verify with my Velodyne SMS-1 that it has NO effect on the Sub output or frequency response. What it does do is cut down on vibrations within the room from other objects that may also be on your floor and therefore "energized" by the sub's output. If you have people below you or hear many things rattling in your room when the sub is active, then I would say it is a wise choice.
