If your current speakers are Paradigm Reference Studio 40s, they aren't anywhere near flat to 50 Hz. Tom Nousaine measured them for Sound & Vision several months back, and if my recollection is accurate, found that they started rolling off somewhere around 70 or 80 Hz.
Given that they provide you with, in your words, LOTS of bass, I don't think you have to worry about other bookshelf models falling short.
(Also, you shouldn't take this as a slam at Paradigm. All speaker manufacturers exaggerate bass performance. And the 40 is an excellent bookshelf speaker.)
