I decided not to listen to any of you folks and replaced the screws on my RSW-10 with $2.00 < worth of Klipsch spikes.
Here is how they tuned out:
I can now knock the pictures off the downstairs bathroom wall with the sub turned down 4 clicks from where it was set before. Quite an improvement eh?
Seriously though, my carpet is not all that thick and it did help sharpen the bass notes and I have less echo in the 45 degree corners (help, I have two 45 degree corners, one is a 4 fireplace and the other is a 2 whatever. I get an 8 db gain in the 2 corner and its on the opposite wall and going through two full length couches and a large leather chair.). From my listening position the sound is less muddy will watching The Two Towers as it was last weekend so I guess I will keep the mod.
