altec 515 and hornresponse

patriz · 20th August 2007, 04:29 PM

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.
