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!

Forgot to include this: One area in which a vertical array of multiple small woofers has superior room interaction relative to a single large woofer is in the floor-bounce dip. The multiple small woofers will have their floor-bounce dips at different frequencies and so they will tend to fill in for one another. The single large woofer won’t get that benefit, though its dip will be smeared out a bit compared to a single small woofer, and therefore will be slightly less deep. The ear/brain system is fairly forgiving of the floor bounce dip because it occurs naturally all the time, but minimizing it is still beneficial.

I can’t think of anything to add as Duke knows a lot more than I ever will!!

We are lucky to have such knowledgeable contributions!

Agree 100% everything Duke said!
