Most full-range speakers can benefit from adding a subwoofer (ideally two - one each for the L/R channels). You will definitely get increased bottom end, greater ambiance, and improved soundstage. The trick is blending them with your mains - you really don’t want to know they are there other than hearing the perceived benefits. This takes some time and experimenting to do it right (phase/low-pass filter/volume). Worth the effort. Jim Smith’s book/DVD “Get Better Sound” into the details/process very nicely. Good luck!
