[QUOTE="Jeffdachef, post: 8151466, member: 650438"] How to calculate cone area Cone area = pi x (r x r) pi = 3.14 r = radius of sub One 8" = 50.27 One 10" = 78.54 One 12" = 113.1 One 15" = 176.71 One 18" = 254.47 Two 8" = 100.53 Two 10" = 157.08 Two 12" = 226.19 Two 15" = 353.43 Two 18" = 508.94 Three 8" = 150.8 Three 10" = 235.62 Three 12" = 339.29 Three 15" = 530.14 Three 18" = 763.41 Four 8" = 201.06 Four 10" = 314.16 Four 12" = 452.39 Four 15" = 706.86 Four 18" = 1017.87 On the same power it should be louder with more cone area [/QUOTE]
