I have been very confused by this for some time. I have LSi25's as my mains, LSiC as my center and LSiFX's as my surrounds. Right now, I have my mains set to "large" and everything else set to "small". Is this correct? I assume it is since the 25's have a powered subwoofer and so have the full frequency response range. However, others have told me that ALL the speakers in my setup should be set to small. PLEASE HELP!
