not really, larger subs tend to have decent efficiency and bigger displacement moves more air

hey, it's true

take DDaudios subs for example

the dd9500g specifically

10" = 87db

12" = 89db

15" = 93db

18" = 94db

or the JL w7

8" = 82.7db

10" = 84.3db

12" = 86.2db

13" = 86.3db

and yeah I'm sure you can argue with a good setup a 10 can beat a 15 and what not but...general terms an 18 covers more area than a 10, it will move more air if played to the same type of sub 8 inches smaller

And sure, box dimensions are like 80% or higher of the sub output, and can completely demolish the need to even look at efficiency, but we don't need to get into that

your using data from stuff under 18 inches. There is a reason above 18inches is rare. its because after 18 mores law comes into play

I can't find anything on mores law online except computers and morals

could someone link me or explain?
