Is the w7 even parabolic? It looks closer to a hemisphere to me.

Wha?

A hemisphere is a parabolic shape, there, buddy //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

A parabola has exponential growth. The sphere, or half of it is technically a special case that does not display exponential behavior.

Depending on how exact you like to be, you can calculate it as a hemisphere, but if it is parabolic you wont get the exact answer.

That's all I was saying.

I get what you're saying, but I doubt the difference, well, makes any difference.

take a cross sextion of the cone, and you are looking at a parabola. there's no need to get all technical in here with growth, it looks like a parabola on a piece of graph paper.

if anyone said this - i apologize because im too lazy to read that firs tpage.

to get the SD of a speaker, measure from middle of the surround on one side, to the middle of the other.

then divide that in half, and do pi*r^2.

all done. it wont be EXACT. but it will be close enough that it wont make any difference.
