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 added 2" Star Sound threaded brass cones to the feet of my RELs for a considerable improvement. Tightened it up and generally improved it.
I added a home made platform under my sub and it made a great improvement. I spiked the platform thru the carpet into the floor.I also added spikes between the sub and the platform. Much faster and more room filling.
Great timing for this question as just yesterday I put a piece of porcelain tile under my REL sub. Still evaluating but initial reaction is not favorable. I think the tile is too thin. Also, it's just sitting on the carpet.
I think I'll look into Stanwal's idea.
RELs come with spikes according to the manual but I bought both of my Stadium subs used and didn't get them. If the Star Sound are too expensive I would experiment with lesser spikes to see if they help. I have forgotten the exact thread size.
