That only makes that guys post even worse.We are taking about square woofers by the way. But ya that was a horrible attempt to find surface area of a cone by the other dude.
you would need to give up a lot of room to properly fit four 15's...ok here's another thing im considering and need help with, i found 15" kicker cvr's for 98.00 american, now what if i did 4 of these?......so 4 15" cvr's vs 3 12" L5'S or 2 15" L5'S.....yeah i know the cvr are only 500rms each but with my amp doing 2000rms i could run 4 of those 15's.....what you think?
(3.14)(radius^2) for a circle.I'm not getting how 2 15's have more cone area than 3 12's...2*15=30 3*12=36???
