I would think more control would be had with multi surface treatments rather dependent on covering an area with one large surface. A large rug will absorb only high frequencies. In order to increase the bandwidth I would highly suggest a felt rug pad. They work well, ime.
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?
