Cone area?

[JoshC 10+ year member]

So from what ive comprehended more cone area = more output. So what im trying to figure out is would i get better overall output with 2 8's or with a 12? How would i even go about calculating that? Either have 600 to throw at even. so 500rms 12 or 2 250-300rms 8's

If i get a 12 im pretty set on the sundown SD12

As for 8's anything i can find a pair for 150 that makes 4ohm load. New or possibly nice used stuff

Depends on efficiency, box.. Specs... Use pie x radious squared to.measure cone area, like for the 8s, 2pie4 squared, the. 12pie squared and see.whst comes.up.

Cone area is just: pi*r^2

Where r is half the diameter of the sub (roughly...specific cone diameters are not going to be exactly 8" or 12" etc...)

8's=100.53

12=113.09

So the 12's have slightly more cone area. 8's box would be built to spec sealed, 12 box would be 1.15 sealed. Both wedge type boxes, 8's possibly a rectangle

Saw thoughs daytons for 145 a pair shipped here.

8s ported over 12 sealed

Well im limited on space 1-1.5 is all i really want to give up, plus ive had port noise so far since im in a single cab. Havnt tryed a aero port yet though

do 2 sa 8s with 6in aero port

or just round the ports inner edge out and make sure you have it secured well.. im running almost 3k to a single 15 and i have none..

A 6" would have to be like 3 feet long to get a decent tune for a pair of 8's.

Although the 12 has a slightly more cone area, the 8's more than make up for it in motor force. With 1-1.5 cubes, it's a no brainer. Do the pair of 8's.
