Missing TS Parameters for Hornresp

Hi all, i have a load of old woofers sitting around and ive been studing hornresp for a few weeks now, issue i have is that my subs appear to be cookie cutter chineseium and are missing a bunch of the parameters needed for hornresp.
I have a DATSV3 and that, also, doesnt give me the parameters i need.

My question is, given that ive designed a horn that im reasonably happy with (96-100db from 26-80hz), is this planned response then irrelevant without the driver parameters, or will be be close, but not accurate?

I have the SD and the LE from the dats, but virtually nothing else and i need SD, BL, CMS, RMS, MMD, LE, RE.

Thanks in advance,
Adam,
