Well, a bit more than that. My PCs playing up a bit. That Vas seems very high for a little 3in driver though -anyone got any measurements to confirm the PE data?

Godzilla,

Im in Spain right now, but I get online for a couple minutes to check my email, but I dont see any pictures of my BIB on your website, do I have to wait until I finish my BIBs for pictures?

Save us all, they couldn't be much more different if they sproted wings and called themselves mushrooms.

Try a line length of 67in, Zdriver 13.5in & terminus area of 25in^2

Apparently the Excel 2K I posted isn't backward compatible, so here's a more flexible version:

Maybe I'm wrong, but an Excel seems incorrect.
How can you summ Sm in sqr inch (C8) with baffle thickness in inch (C9)?

My 0.2

D=depth of enclosure
W= width
H= height
t= baffle thickness
d= depth of throat

Sm = W*d
D= d+t
H=L/2

d=sqrt(Sm*sqrt(2))
W= Sm/d
D= sqrt(Sm*sqrt(2)) +t

All dimensions are internal.

p.s. Maybe I'm wrong or not

im sorry i tried searching but....im challeneged, and its summer holidays, so i was wondering if someone coudl be ncie and answer a quick question.

How do i find out how far the baffle goes from the bottom of the cabinet? i calulated it so that at the bottom of the baffle the SD=1/2 sd of the throat. is this right? i remember someone saying they put it like 7" from the bottom....but im not going to build these going by what i remember.
