WinISD reduce my SPL every time

[infinia]

i went to Solen yesterday and finally i bug higher gauge for inductor. I talk about efficiency and inductor resistance with him and an inductor with no efficiency reduction will cost me a legs and will be gigantic (compared to speaker size). So i go for middle solution. I will have between 1 and 1.5 db drop instead of 2.5-3db..

You mean ohms not dB. I found the most cost effective way to to minimize Rdc and still get good bass is to use medium gauge wire with much less turns using laminated cores.

[About WinISD, except rare case, in cannot save the new drivers settings because winISD math don't fit with all drivers specs. How can i get precise simulation if i have to delete randomly few variable to let it guest the real value ?

The software said one or more value are wrong but not which one so maybe i delete the only good one and let it calculate from others wrong.

Re WinISD Alpha
I think that is the same reasons I went Unibox instead. I really like Unibox charts... Xmax versus freq and port air speed.
I still use WinISD beta for quick box size and tuning.

I believe the results of SPLs (1W/m) are very accurate in Unibox, but it is difficult to verify absolute levels with cheap microphones. We really just care about matching the relative levels to other drivers anyway.😎
