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?

I do this with my Rel Strata III down firing sub. I flip it over so it is up firing, put a nice thick piece of wood on top of the now upward sitting feet (I use a large 1" thick maple cutting board) and put something heavy on that. I also recommend getting it out of the corner. You will have to turn it up a bit louder but with both of these changes you will now have something that is absolutely faster sounding with better overall pitch definition.

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.
