Desingers, no matter how talented, can be of a certain mindset and nothing will sway their beliefs. Like Milpai said, try a nice sized section of tile or wood to rest the speaker when upon the carpet. It could very well be that the designer tried all manner of footings and found the best solution (doing all the homework for you).
By the way, unless you have the proper depth and know what you're doing, I wouldn't drill into the bottom of any speaker.
All the best,
