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?

I just took a look at your system and all I can say is WOW, nice setup! Are you asking this question because your 801s are too big for your tastes or room or just curious about an alternative configuration? Your question has been one of the ongoing debates in these forums. It's not a dumb question at all and should inspire some great responses.

There will be those like myself that use monitors with a sub because of the great soundstaging capability and ease of placement of small monitors combined with the versatility that a movable/adjustable sub bass system provides.

On the other hand there will be those that prefer floorstanders because of the potential difficulty of tuning a subwoofer to match monitors seemlessly or they may feel that full range speakers offer a more coherent sound.

I've never had floorstanders in my system so I can't offer any valuable insights into their setup. I enjoy small monitors because of their ease of placement and because I can own more than one pair for about the same price of a good floorstander.

So is a monitor/sub combo as a good as a floorstander? I think it depends on what you're comparing and how well each is setup.
