Z-Driver calculation for iBiB

ziocalepino · 12th July 2011, 09:55 AM

Hi all, I would like to build inverted BiB using ZiIllaaudio calculator. Looking at this argument in other threads it seems overall dimensions of cabinet are the same both for ordinary and inverted BiB. But Z-driver value cannot be the same of course. I've found a value of 0.416 * line length Can this work fine? Or are there other calculators for iBiBs?

Thanks a lot

Thanks for link. Another important, for me, question is: is there a real advantage to build inverted BiB instead of normal? A part no dust into cabinet...

If your driver doesn't warrent a long line, your BIB is going to be too short to use the ceiling effectively for loading. Then it might be better to invert. Also for some it might be an opportunity to get the right driverhight without resorting to tricks and compromises.
