The Podiums are, of course, designed to decouple the speakers from the floor, but when speakers are placed on stands, there will be some vibration between them. So even if the Podiums have their intended effect, they obviously can’t prevent interaction between the speaker and the stand.Yes, you’re right. It’s a consideration I have contemplated myself actually.
Laminating a softer material to them can dampen the ringing and also move resonant frequencies outside important frequencies.
@arthur1260 whipsaw has brought up an important point, and I’m likely to try something like https://www.secondskinaudio.com/sound-blocking/luxury-liner-pro and wrap it around the uprights, secured with tape as a proof of concept, before trying something more permanent.
I’d prefer https://www.secondskinaudio.com/acoustics/mega-zorbe-pro
however the white isn’t going to look good for me. Maybe both?
Another approach was to use a corner foam bass trap and cut out for the front leg of the stands and sit it in there to help clean up imaging, as back pressure moving around the stand mount’s bass driver will be reflected from the front edge of the stand closest to the speaker.
To mitigate the seeming loss of bass, because it won’t be transferred through the substrate, using a TMD on top of your speaker, will tighten up the bass, the bass will be punchier and have more speed.
It will require tuning the mass, and playing with the absorber material, however even without precision, benefits for modest cost and time will yield good results.

@audioguy85 - I'll be checking out atabites, I've only used ilmenite also with good results. Cheers.
