I agree...put a sub on springs is ridiculous at best.Maybe good if your trying to bounce around like a pogo stick.
Subwoofer Footing - Connect or Isolate?
What is considered the best way to "foot" a subwoofer, should one try to connect it with the floor or isolate it? I have a REL 7i that I have firmly coupled to my wood floor with the weight of a 42 lb curling stone, mainly because it looks cool. Would some sort of isolation be better and reduce resonance from the floor, or could the connection with the floor help "drain" resonance from the subwoofer cabinet?
