This is your only solution... and maybe you can find someone near with one. Been there, done that with numerous drivers and any arbitrary enclosure is a wild stab in the beginning & a second guess in the end because without proper specs you won't even know what type of enclosure is suitable, much less the size range. You'd be surprised how far off many common drivers are found to be.
I expect that the OP might ask to have it tested by someone near if they have one. Not sure how you twisted that into purchasing.
When I first saw that site some time ago, I thought it was going to be the next best thing since sliced bread, that's until I realized they use manufacturer stated specs, not tested for actual.
It's cool. I seriously doubt most will buy one even in this hobby where they will spend twice that amount on a single driver. A shop might have one... never know until one asks around.
Not sure.. I mean, that is the exact reason I bought my first Dayton WT(2,3?) some years ago. This was before Elemental Designs started blowing out their EQHS woofers. One of the key things I remember while getting a grip on driver parameters & applications was that many manufacturers don't give accurate specs. The woofer tester confirmed that and became a highly effective tool when using inexpensive drivers... the biggest culprits of erroneous data.
