I am planning to use my Wharfedale Diamond 220 on a Speaker stand. The floor is hard (marble). The speaker comes with rubber feet (shown below). The speaker stand comes with metal Spikes. This speaker is bottom ported and there is a plinth at bottom for better bass. Now I need your valuable suggestion on right usage of spike/rubber-feet for both Stand and Speaker.
