It's a good thing most (if not all) speakers weigh considerably more than a stick and are constructed much more robustly, obviating the need for a Podium to keep them still enough to be listened to and enjoyed with less costly devices.
There's a point to where such isolation is unnecessary (and even overkill), allowing one to spend much less and still get great results. This kind of reminds me of all the isolation and LIGO discussions one member used to bring up, ad nauseam.
All the best,
