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 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.

Any type of spoke should improve it. Make sure the spikes are adjusted so there is no rockIng of the woofer- it needs to be very secure.

I have an old school setup.
Nikko Alpha 2 amp
Nikko Beta 2 preamp
Nikko Gamma 1 Tuner

I run 2 pair of DCM Time Windows 1A
and 2 DCM 10 inch subs.
My set up is in a 12' x 20' room with not the greatest set up as far as accoustics. I will try the cones, but is there any opinion on using say a granite base or the auralex sub dudes?
