I guess it all depends upon what you consider a very large room. After considerable experimentation and measuring using calibrated tones and an SPL meter, I found that about eight feet out from the back wall provided the most neutral bass response in my 25' long room With the U-1s.

Only when you do not have an appropriate amount of diffusion. I use a forest of bass traps to further flatten the bass and to minimize that issue. Further, I have fake ficus trees flanked on either side of the stats to address the first reflection points. The stage I get is both deep and precise.

As a minimum. The rule of thirds applies in all directions in order to minimize room modes. I would be curious to see pics of your arrangement. Mine are available in the gallery.
