Question about using floorstanding speakers with a sub
So I have RTi 12's, and I have them setup to be "small" since I have a Polk DSW Micro Pro 660 sub. I guess my question lies in wondering whether or not my rather large RTi 12's are really being used to their fullest in this kind of configuration? I mean looking at it, the RTi 12's have 3 subwoofers built into them. If I have these speakers setup to be small, does that essentially mean that the tweeter/mid-range are really all that's being utilized and the subs are somewhat dormant? I know there is a crossover which I have thought to mean that the subs do have some stuff going through them, but am I right in thinking that a rather large part of my rather large floorstanding speakers really aren't being used?
I guess part of the reason why I ask this is that I've been entertaining the thought of going to bookshelf speakers in my living room, and if a significant part of the floorstanding speakers aren't really even being used, it may accelerate my decision. I do a little bit of everything with these speakers; music/movies/gaming/tv. TV doesn't really bother me either way because I usually tend to be underwhelmed at compressed TV audio.
