Downwards firing sub woofer on tiles: practical solution to stop the jumping sub

[Radar]

I have a downwards firing sub, and when volume levels start rising, so does the jumping height.  This seems to be due it being of a tiled floor.

What practical solutions are there to resolve this ?  I understand a cone of sorts placed under it may help, what about lifting it by extending the legs somehow ?

Are there locally available solutions to this problem, or is it a DIY job ?

Please share your solutions.
