Anyone have the Unibox database parameters for a Shiva 12 inch? If so could you e-mail them to me?
Thanks

Download all the ZIP files together with the Unibox program. Then import all the (unpacked) files. After having appended all files, sort on name. You should be able now to find the Shiva in the list (just before the Tempest). Sven.

Thanks so much !!
Those are a big help and confirm that I got the right data when I was digging data out of the Shiva white paper. But the program call for a bunch of other data points which I can't find or don't know the meaning of. Maybe they are not important to running the program?

Here is the onlything you should fill in:

Driver Parameter Box:
Fs
Re
Qms
Qes
Sd
Vas
Xmax peak
Nominal Power
(Le, Le2, Re2 optional)

External components--set to 0. (you won't use it)
...exception: set Rs=0.1ohms (approximates the series resisance in the cabling)

Closed box:
qtc
Physica Vb
(Qa and Ql are set with the dampening/leakage drop boxes)

etc....

as you can see, you only change the blue ones. the red are calculated. Some of the blues you change using drop boxes. some of the blues you leave alone at 0.
