Small drivers vs big drivers


Hi,
I have a question that is always in my mind recently. I see some speakers with small  drivers (5-9 inches) that is reviewed to be able to throw out big sound stage and go down to 18hz-20hz. Some other speakers with big drivers (10-15 inches) though are commented to have 'big sound stage' but can only go as low as 30-35hz. 

To make the situation more complicated, some speakers have small drivers but there are many of them. Can many small drivers be compensate for the size limitation?

I don't know which specs determine a wide sound stage and the ability to reach low frequencies.  What is the pros and cons of each design?

Thank you!

Huy.

The lower bass response of a speaker is so incredibly fungible. Room gain and placement matter a great deal, so best not to read too much into the spec itself.
I will say that good room acoustics can make a speaker sound bigger, deeper, and tighter. A good 2-way speaker in such a room can be very satisfying.

I own 2-ways with 6.5" speakers. They sound great, but they'll never have the deepest bass, and dynamic range of 15" woofers. for my apartment lifestyle, that's kind of irrelevant though.

Line arrays may make up for the displacement, but their real benefits come from imaging, wide sweet spots, and reduced room interactions which yield better clarity and imaging.
Adding to @twoleftears :

The 2.5 way speaker is a little miracle of efficiency, space and capability.

Two 8" drivers are still only the radiating surface of a 10" or so, but the increased efficiency, and reasonably extended bass output make them superbly enjoyable compromises.

Best,

Did you mean sound realistic, or feel realistic?
I ask because I am always curious how much we actually listen through our skin than our ears.
