I recently installed Auralex SubDudes under my KEF Reference 104.2s to replace spiked hardwood planks, the spikes of which penetrated fairly thick carpet covering a second story floor. The bass seems tighter and extended a bit, and for some reason, the depth of sound stage is increased. The SubDude under the Velodyne HGS-15 is very effective in eliminating the boom and extending the bass, so I thought I'd give a pair a try under the mains even though they had no boom. I'm pleased with the result.
The SubDude under my sub is larger and industrial looking whereas the units under the mains are 15" square and covered with a black material so they look attractive.
