Does subwoofer + bookshelve=full range speaker?


I am sort of new to this hobby so this may seem like a dumb question.
I always wonder if add a good sub to a bookshelve speaker do you get a same performance as the large full range speaker.ie if you add a subwoofer( assuming a good one) to B&W 805 or Martin logan entry level model . do you get the same performace as N801 or prodigy or more because the subwoofer in many instance will go even deeper than the full range speaker?
if not why not?

"the same performance"?

From the perspective of soundstaging and image control, you may well get BETTER performance. I would have to pay a LOT more to get what I currently have with my Nautilus 805s and my REL Stadium III Sub. I personally do not find the 805s to be all that light in the 30-50 Hz range (partly because of the amp I use) I would like to lose the metal dome tweeter, however.

If your goal is to reproduce the cross-over designs of the 3-way, I would expect the answer to be no.

If your question has to do with whether or not you would like what you HEAR with monitors or planars plus sub, the answer might be yes.

In my price range, I have to live with trade-offs, and this is one that personally pleases me.
