In Reply to: RE: How do you calculate BIB enclosures? posted by Eldragon on January 01, 2015 at 11:09:02
Line length = (speed of sound)/2/Fs
Folded height = line length / 2
Vb = 20*Vas*Qts^1.25 (Vas in ft3)
Sm = Vb*1728/(Folded height)
Depth = sqrt (Sm * sqrt(2)) (internal dimension)
Width = Sm/Depth ( " )
zdriver = Line length*.217
a-b-c = Depth/2

grindstone .... depending on driver, is there a easy way to calculate the low frequency, not just by length? I don't want to take time to do in HornResp.
Thanks, Zene
GM is the alignment formulator so if he's around perhaps he can comment if you post your driver stuff. Otherwise, maybe check the fullrange board at diyaud -- there are a couple BIB threads that he may be subscribed-to or perhaps someone there would model your driver for you.
Grindstone... thanks for quick reply. Will do follow up.
