Aurios 1.2 under Velodyne F1800X Sub ?

Has anyone experienced an improvement from floating a Subwoofer with Aurios? I have a Sistrum SP4 stand that tightened up the bass output and was wondering what the affect of the Aurios would provide.

Just a follow up, I tried the 1.2's briefly (an improvement) and then upgraded to the Aurio Pro's which tighened (almost deepened the bass), especially with the 25lbs of #7 lead shot sitting on top. I had to turn the sub down to 2 it hits so hard now.

Seems to have made an improvement. Would you describe it as significant; more particularly, was it work $350?
