Notwithstanding as to how well the S38s sound to my ears after calibration, should they ideally--if not initially--be configured as "large" or "small" speakers in the receiver setting? When I set them as "small" in my Sony DA4ES receiver, the bass output is very minimal--almost as if the speakers were functioning as small satellite surrounds; however, when set to "large" there is noticeable bass output. This finding sorta flies against the given rule of thumb that only tower speakers should be set to "large". Given that I am also running a sub and will be using my HT setup primarily for movies--should I configure the S38 as "small" or "large"? Just wondering, since I reckon that if I set them to "small" in my particular setup I wouldn't be making best use of the S38s as far as acoustical output is concerned... On a similar note--would the JBL S-Center be considered a "small" or "large" speaker? Thanks!
