Platform stand for Cube Audio Jazzon speakers

Clearly the Townshend Seismic Platform is the best option, but it is very costly.  Does anyone have any suggestion about a reasonably-priced platform for the Cubes, particularly one that will accommodate Gaia footers? Note that there is no way to affix the Gaia footer directly to the bottom of the speakers as they are entirely open; hence the need for a platform. Thanks for any recommendations.
