Joe, it's not really new...and to each their own... but the general thinking is to set even speakers that are physically large to the "small" setting, as the sub is still the best speaker to handle the bass. Plus, the subs' amp takes a good load off the receiver, which now doesn't have to push watts for those lower frequencies.

Personally, I have my Denon receiver to send bass to both the M60s and the sub, because in my poor acoustic environment, the more bass sources, the more even the bass response.
