I bought this sub for cheap and I'd like to make better enclosure for it. But I can't figure out what model this is (tried reverse image search and one reddit post but no conclusion) and I have no way of measuring the t/s parameters now. So can someone identify this or tell me how can one measure the t/s parameters for cheap.
Or the not best option, could someone say what could be good ported box for this based on the sealed that it came with?
Thanks

The basket/magnet/back plate look like the Eclipse 871214 shown below. Maybe it was reconed, and the magnet cover removed?
Image also has basic Thiele/Small parameters written on it, but I didn't try to confirm their veracity.

That could be plausible, but what I can see the cone if so different that those t/s parameter probably are nowhere near the real ones
Do you have any test equipment? Multi-meter that's accurate across the frequency range you want to measure, signal generator, etc.?
A couple links that cover measuring/calculating parameters with older methods:

Alternatively, are you interested in learning how to use REW?

Well my dad has multi-meter lying around and said he would give it to me and I have no clue how accurate it is. Signal generator if my hz generator on my phone counts yea, if not nope. REW would be cool to learn but I have not gotten around to learning it, now is probably the best time because I have reasons to do so.
On the multi-meter, you have to be careful since many aren't accurate when they get much away from 50/60 Hz (AC line frequency). With a subwoofer it's less likely to be a major problem, but it is something to be aware of, and it's worth looking up the specifications of the meter if they are available.
