Has anyone worked with this driver. I’m thinking 2-way, but not sure. WF223BD01_02

I’ve been drooling about the WF223BD and the WF275BD for a couple of weeks now for future projects. They look exceptional, at a pretty reasonable price.

Just be aware that the graphs changed from 2015 to 2023 - be sure of what vintage driver you purchase by asking for the date of manufacture from the vendor - very different break-up modes.
This one is from 2015 → Wavecor WF223BD02 - 9″ Woofer 8Ω
Yours above is from 2023.
Same looking impedance though . . .

Some guy over on HT Guide tested the WF223BD01 version,
Thank you,

Mr ling Gowa, I am currently working on a SW223BD01 + GRS PT5010-08 + AMT3-4. “working on” may be stretching it, I have the drivers, done some measurements, done some crazy simulations and even done some CAD designs, but then somebody switched on summer. And - gosh darn it - currently working on a small pair of speakers for my sister (hopefully ready for the - fingers crossed - CSS event). I hope that the sw223 pair will be ready for inDIYana2027. Stay tuned.

None of the BD02’s parameters changed when you compare Wavecor’s PDFs from 2015 and 2023. They only added some “after burn-in” parameters in 2023 that were blank in 2015. It’s strange the SPL measurements would change then. Looking at Wavecor’s SPL files, I would tend to believe the 2015 results (blue) over the 2023 results (red). The 2015 version looks more like an infinite baffle response from a driver with Qts under 0.5. You could ask Wavecor.
