CFB, I have to say you've been in rare form this week:~)
And now back to the subject matter at hand. I own the Velodyne HGS 15 and use to have it sitting on my carpet. I know what your thinking. Energy is escaping through the bottom of your speaker. It was recommended to me to use spikes and load some weight atop the speaker. About the time I was shopping for spikes I remembered having an amp stand in the closet. That's when the light came on! (The closet light). I set the sub on top of the amp stand raising it off the carpet. IT WORKED! I have not loaded any weight yet but will experiment with that this year.
