dap audio mb15

Hey People.
I've got a pair of MB-15 Woofers from dap audio laying around and thought about building some enclosures for them. however i can't find the more specific specs that most enclosure calulators require anywhere (like Equivalent Volume (Vas), Free Air Resonance (Fs), Total Q (Qts) and so on).
Has anyone worked with these drivers before or knows where to find out the parameters? Keep in mind, that im almost a complete newbie when it comes to building speakers and i propably don't have any of the equipment needed to measure these.
Driver maunal (at least the one i could find) in the attachments 😉

Cheers
