Sorry if this has been covered before, tried a few searches but nothing came up that I could see as answering this:
I'm trying to model some enclosures using Ground Zero's PRs, they provide the following specs:
Fs: 30Hz
Vas: 15.46l
Cms: 128um/N
MMS: 375g
Sd: 118.3sq inches
but leave out RMS and Qms-meaning BBpro will not model them for me-how can I derive Qms and RMS?
I've mailed them for the spec, but they just linked to the PDFs already on their site.
Thanks in advance

I don't suppose you'd consider a better box modeling program? For any useful work, you'll also need xmax.

Fastbike1, thanks for the link, I have tried loading in the spec from the woofer and PR, it still won't give me the Qms or RMS:
Fsp' (Hz) 26.66 Vasp' (Liters) 61.40 Mmp' (gms) 475.00 Qmp' 0.00 Vab' (Liters) 133.17 Tuned Fb (Hz) 32.22 Cmp(mm/N) 0.075 Rmp(kg/S) #DIV/0! Qb (Total Box Q) #DIV/0!
I've tried adding mass to the PR, changes all the figures in the pasted section above-asides from the Qmp and Rmp /Qb-any ideas what I am doing wrong?
