The title say it all really. What I'd like to know is since the center channel arguable works the hardest in a surround setup, is it possible that a more dynamic presentation could be had by adding a sub to provide a low frequency boost to, and lets face it, the vast majority of rather bass light center speakers out there and thats not discluding my own (see sig). Has anyone done this already and found it next to useless or a worthwhile to-do. Obviously I don't intend to pair a Servo15 to the center channel but rather a small and compact sub, such as a REL Quake or BK XLS 200. Cheers for any input.
