Default altec 515 and hornresponse

I want to design a 80-200hz horn but I can't find the Altec 515B Thiele and Small number to put in Hornresponse, .
I have found those:


but they aren't the one nedded by the program,
Does anyone know where to find Altec 515B BL, CMS, RMS, MMD, LE ?

Patriz, as far as I know, Hornresponse will calculate those values for you ( except Le). You do need voice coil Res, cone area, Vas and Qms and Qes. Just double click on the parameter you want in the horn response screen.

'Le' on my four is around 1.4 mH.
