Down firing sub tweeks

I use a down firing sub on a carpeted surface. Are there any specific tweeks available to better disperse the bass ? For example, would a product like Auralex sub dude make any improvement, or is that just to reduce the bass below the unit? ( Like in an apartment setting). Anyone use a "base" of some type, or is there is there an isolation base surface known to be better than carpet?

PTM, this is interesting as I'm always looking to experiment. Is the sub simply sitting on the floor or did you fashion some type of feet?

Just sitting on the carpet in my room, so it doesn't scratch.

I have a 3 inch thick maple cutting board. Think I'll give it a try.

I decided to try and experiment with sub bases. I made them out of (2) 3/4" thich MDF glued and screwed together. I then glued on 1/2" oak plywood for a 2" total thickness. I wrapped the out side edges with aspen wood all stained to match the componet stand I built previously. Not willing to spend big bucks on cones at this point I used 3" x 5/16" brass screws that extend 1" below the bottom for spikes. Once the 5 coats of gloss clearcoat set up I will try them out and report on any impressions.
