I have a dali E 12F subwoofer on a tile, with spikes under the subwoofer.

I would like some feet under my tile or under my subwoofer(mabye both) instead of the spikes.

I have seen the sonic design feet where the feet for cd's amp's where recommended to me(don't know if they are high enough) for a okay price (only need for 1 speaker not a set for 2 speakers which cost twice as much)

I could also buy some deflex superpods, although i think they are a bit expensive, live in denmark so delivery isn't free(have ordered the small ones for my 2 small amps that i am wanting to see/hear if they make a differnce) http://www.mains-cables-r-us.co.uk/equipment-supports/625-deflex-audio-superpods.html.

What would you recommend me, feet under my tile and use the spikes on my subwoofer?

Feet like the sonic design or superpods under my subwoofer (if they are high enough)and nothing under my tile

Or the last option feet under my tile and subwoofer? (would use the same ones, only difference would be the ones under the tile is a version that can handle higher weight, then the ones under the subwoofer)

Have heard that something like the sonic design and superpods feet are often better then spikes
