I bet there's a peanut in there instead of a magnet.

That looks very similiar to a Tang Band spec sheet by the smoothed graphs and type set.

The phase plugs look like they came off an Audio Nirvana.

I was thinking the formatting was oddly familiar. Good eye.

Quite.

Paraphrasing / condensing my reaction on the aforementioned UK forum...

I suspect they're probably out of the OEM factory that produces the Audio Nirvana range in Taiwan; cones, frames, magnet, copper-plated aluminium phase plug & spec. sheet is all consistant with many of their base FR products.

On the face of it, it doesn't look too bad; assuming they're accurate (big assumption -heavily massaged plot etc.) the basic balance of parameters seems sensible, and it's got some features that appeal to a lot of buyers -cast aluminium frame, pretty phase plug, nice quality paper for the cone etc. However, I do have some fairly major reservations. For a start, what on Earth does a 4in driver require a whizzer for? Not too sure about that roll-surround either; combine those features together & off-axis performance won't be fantastic. I don't like the neo. motor either; they're generally done for drivers of this kind either for cost or marketing purposes, and this is obviously no exception, the probable only real benefit being less disruption of the air-flow to the rear.

Still, the final arbiter is the ear, and at ~40 for a pair, it might be worth a punt. But I rather think the Fostex FE103En; Mark Audio CHP70 / EL70 or one of Tang Band's better 4in units would quickly show why it's worth spending the extra. One way to find out of course...

Right indeed, Scottmoose, they are said to be made by the manufacturer of Audio Nirvana. You know what, they sell it on Taobao for a lot less! Something like USD$14 for each unit! The cast frame looks great but there's no vents for the spider. The neo magnet is too small for my taste.
