In my experience, adding a sub can really help, but only if it's a good sub and only if you really work at positioning and room treatment...or if you 'cheat' by using a parametric equalizer.

If you're willing to go up to something like the Rel Strata and spend the time needed to set up your system carefully, you might benefit a lot.
