Hi,
I got this pair of woofers for free when I did a deal about its sibling P17WJ.
I say sibling because they are more like distant cousins than brothers Except the magnet system NOTHING is the same... WH has a stamped basket, feels like a little thicker membrane and the dust cap is as soft as concrete, way stiffer than the membrane, made from thick polypropylene maybe twice as thick as the membrane, you can't push it in even one little bit. The membrane is also s lot flatter and the dustcap is probably 2" wide, yes just the dustcap. It looks like it has a 32mm voice oil as WJ but that is all I can get out of them...
The driver also a lot shorter than WJ when standing on their magnets.. makes me think about auto sound...
Anyway i was wondering if anyone have any information about them? A datasheet or measurement would be great but right now anything helps in finding out what to do with them...

The "H" is for 25mm voice coil where the "J" is a 32mm voice coil. It might have a similar motor to the P13 which is ø74 where the P17WJ is ø90. Other than that, I have no info.
You may want to add some pics.

As said before here, Vifa has produced hundreds of varieties of the 17cm driver. The badge says almost nothing. And it could even be that it is a fake Vifa.
There is nothing similar between them than the magnet system. Believe me on this.. WJ feels like a 500$ driver alongside the WH. If you check the WGversion out it is kind of similar to my WH, stamped frame but with WJ cone.
The WH is a completely other animal.
Is it the bass mid on this photograph? That is the right unit, the link above refers to the right datasheet.
