A speaker's characterstic doesnt have to relate to its specs, although it often does. Dont worry if you dont understand all the technical sides of the hobby, you will eventually if your really insterested in it. Of course no speakers sound alike, but I had a set of speakers somewhat like yours a few years back before I really got into the hobby, although they had a real tweeter rather than a more cone type that you have. The difference in sound quality, detail and smoothness is astounding.
What axioms do you currently have and what reciever? If your happy with what you have now then theres no reason to talk yourself into buying something new, but if you do. Like i said i think you will be impressed.
