thanks!

6.5" = 33.18sq. in

8" = 50.27sq. in

10" = 78.54sq. in

12" = 113.10sq. in

15" = 176.71sq. in

18" = 254.47sq. in

that doesnt take into effect the size of the surround so those numbers should be a tad smaller

The numbers above will be used in most cases. Unless the sub is square.

im talking about the exact figures......not generalized ones......for an exact figure tho you'd need dto subtract the area of the surround

16% - 20% more...I think.

Guess you could go by the Sd...http://kicker.com/ShowPage.cfm?filename=TS_SolobaricL7_4Ohm.html&menu=SUBWOOFERS

Just convert to sq. in I guess.

The subwoofers Sd is the T/S for cone area. Each sub varies, just find the Sd.

Sd =

Area of loudspeaker cone

T/S (Theil Small) Parameters =

A subwoofer's Theil-Small specifications are technical parameters that an engineer refers to when designing a speaker enclosure. The main parameters are known by the letters F,V, and Q. These letters are followed by the either of the two subscripts: "s" for the speaker operating in free air without an enclosure, and "c" for operation in an enclosure of some sort. F refers the speaker's resonant frequency. Below this frequency, the speaker's response drops off sharply. Fs is the resonance frequency of the speaker in open air, and Fc is its resonant frequency in an enclosure. refers to a volume of air. Vb is the amount of air volume in a box. Vas of a speaker is the volume of air that would have the same springiness as the woofer's own elastic suspension. Q refers to the "quality" of the resonance. Keep in mind that optimal values for the Theil-Small numbers vary depending on the type of speaker system.

the sd of a 15" XXX is 74.4 in^2

is that rigth??
