Speaker placement: Rug in front of speakers vs Rug underneath speakers

My room has hardwood flooring. I can get a rug large enough to go underneath the speakers, or one that ends just in front of the speakers (so, speakers on hardwood). This is for a 2-channel set up. Speakers are Sonus Faber Aida (with a downfiring infrawoofer) if that makes a difference.

Is the answer obvious? Or entirely room dependent?
