b/c you get the suface area of a circle by doing Pie(3.14)r2

so you ahve 2 formulas

3.14(62) x 3 (3 12" subs) = 339.292 in.2

and

3.14(7.52) x 2 (2 15" subs) = 353.429 in.2

you get the formula for the area of a circle by doing: (Pie)r2....or (3.14)r2

r is the radius of the circle...or half of the diameter....so 12 inches is 6 and 15 is 7.5.

so you do 3.14(62) then you multiply that by 3 b/c there are 3 12" subs.

and then you do 3.14(7.52) for the 15" and then multiply that by 2 b/c there are 2 15" subs.


and you come up with:

3.14(62) x 3 (3 12" subs) = 339.292 in.2

and

3.14(7.52) x 2 (2 15" subs) = 353.429 in.2

so there you have it.....2 15" subs have more surface area than 3 12" subs.

BUT.....some subs have huge surrounds which takes away from the surface area of the sub....and they make up for that with excursion. :-)

I think muddy waits for someone to say "would'nt that be more surface area" so he can smack them with the math, I love it!
