Don't confuse more bass with lower bass frequency. A good Sub shouldn't ADD bass to the sound, only reproduces the lower frequencies your speakers can't handle (in your case anything below 37 Hz, which is not a lot and hardly audible. You feel it rather than hear it).
A lot of cd's these days just don't have a lot of bass in them and sound lean. That has nothing to do with your system and if you want more bass, than it will def. reduce the microdetail of your bass responce in case of a sub that's been adjusted to ADD bass. If you adjust the sub correctly it will not add, but just reproduce the frequencies below your speaker's bounderies. It could very well be the case that your speakers roll off at 40 or 50 Hz or something. Most speakers don't go nearly as low as told, in which case a good sub could be a solution.
But don't expect your lean cd's to sound full of bass all of a sudden. It won't happen.
Hope this helps.
