[Gula187 10+ year member]

how do you guys determine the cone area of subwoofers?

like four twelves vs three fifthteens

LOL, it really is pi(r^2). radius = 1/2 diameter

take the radius, square it and multiply it times 3.14159265358979323846

for instance 1 12" subwoofer has a 6" radius so 6*6*3.14=113.04 sq inches of cone

1 15" 7.5*7.5*3.14=176.625

so 4 12"s=452sq in

3 15"s=529"

how would i figure it up for a square 12" sub

considering squares are supposed to have 16-20% more cone area

which would be 1.92-2.4 inches added to the 12 correct

Go to google and type area of a square formula.

B*H

aka base (times) height= 144

how old are you that you don't know basic area calculations?

thanks guys i was getting confused i got different answers from the guys attha audio shop ther told me to multiply the number of subs

you would have to. you only figured out the area for one sub.

once you have area of one, then you multiply times number of subs

 

[squeak9798 5,000+ posts]

Sd = (3.1416 x D^2)/4

where "D" is the diameter of the cone [the actual cone itself, NOT the subwoofer's diameter] plus 1/3 of the surround (or 1/2 if that be the case)

You can not simply take the diameter of the subwoofer and use that to calculate cone area as has you have to account for the surround. Wider surround = less Sd.

If you want to compare the cone area of various subs, just look at the Sd in the T/S parameters.

the way he explained it three 15's will be 45sq in. and four 12's will 48sq in.

the guy at the shop is a tool, a retarded product pushing monkey, I could go on and on about stupid dumb mother****ers who push this garbage on paying customers.

No one needs to be MECP certified anymore? who hired their retarded cousin to sell subs. OMFG!
