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!

It's not just a question of whether a 7" driver can produce 20Hz, it's surely a question of at what level.

BTW, 3 x 7" = approximate surface area of 1 x 12" driver.

Despite multiples of 7" or 8" drivers having the same radiating surface when calculated mathematically, there's something about a 12" or larger that just sounds better.  Designers went to smaller drivers to make speakers narrow, for ergonomic and stylistic reasons; there's something really special though about a wide baffle speaker that can accommodate a big woofer on the front.

Yes, excursion distance before bottoming out is another factor to be taken into consideration.

This is whole thread shows why I find the Raidho (and similar) philosophy totally unconvincing.
