Cal, you are indeed right on that. I think most phase plug looks like that word too... Except the door knob alternative.
These are made by Gui-Sound. Yes, they are the Audio Nirvana manufacturer.
Guide-sound
The pics in the first page deffinitely look better than what the manufacturer shows. It also has lots of models not listed on the site (strange marketing). Here is a link with lots of models guisound ... I got it from another thread on the site: http://www.diyaudio.com/forums/full-range/128026-fullrange-drivers-china-5.html

Hmmm...
A lot of their products seem to be copies of other drivers...
Fostex 6.5" look alike http://www.gui-sound.com/upload/201041583129614.pdf
Fostex 4.5" look alike... http://www.gui-sound.com/upload/20091215113050438.pdf

Well in fairness, if you wish to make a product to rival / of the same general type as, say, a Fostex 166, you're going to end up with something that resembles a Fostex 166. There aren't all that many practical options available in such cases, so similar requirements tend to beget similar results.
If you'll forgive my pointing this out, there's nothing new about white / off-white cones. It tends to be the natural shade of most brands of paper employed. If we're going to play that kind of game, then Fostex should be accused of copying Lowther, who were producing cones of a similar colour ~8 decades ago, and continue to do so to this day. The defunct Coral and Moth also did -were they therefore copying Fostex or Lowther? In terms of current brands, along with the aforementioned Lowther, AER, Lyeco, Voxativ, Seas, Feastrex &c. all have white / off-white cones. There are doubtless dozens of OEM manufacturers like Guide-Sound that do the same. You only get black cones if you add a dye or some such to the proceedings.
Sorry, I can't buy into the 'copying' accusation. If they were copies, they'd have to have the same magnet, the same frame, the same powertrain, the same cone and the same materials in each. What they are doing is producing an equivalent / rival; ergo the results are determined by the requirement.
a/ They're essentially an OEM brand, ergo, they serve a market. For e.g., someone goes looking for a base-product they can have cheaply modified and produced for their own purposes. They want a relatively efficient, 6 1/2in full range driver with a whizzer cone and a stamped metal surround, similar in fact to a Fostex FE166En. With a certain inevitablity, we see said OEM brand producing just that, as a base model, which can therefore be quickly & easily modified to the client's needs -even down to a pale cone that can if needed be dyed to a different shade.
b/ A basic fact of engineering is that form almost invariably follows function, and the same engineering solutions are going to be employed to answer the same engineering problems. When Ford introduced the Fiesta in the 1970s, Vauxhall did not rush a 30ft long monster that runs on ambergris and diced crocodile penis to the market: they produced the Nova. Direct rival, looks similar, similar engineering. Yes, perhaps they could have done something more radical in engineering terms, but why would they? They weren't trying to make a Bentley or a statement product, they were trying to produce a small, budget car, cheaply. In the same vein, if a far-eastern manufacturer wishes to produce a relatively high-efficiency wide-band drive unit cheaply, to rival an existing product of this type, then it's going to be similar. There isn't a whole lot of choice in the matter.

Scottmoose, you're right that white cones had been around for years, but there are other things that made me believe the Guide Sound speakers had copied Fostex. The 4 incher's appearance is almost identical to FE103E, with the same inverted cloth surround, same dust cap, etc. Yup, white cones are popular among full range speakers, but I dunno why they are almost non-exist in woofers.
hola! this is my web site and sourse isn't Gui-sound only. do not identify it as Audio Nirvana, or Fostex please. commonsenseaudio take care about Audio Nirvana.
by the way - I'm just back from China and Gui-sound made order already, based of my individual design. 7" and 8" with wooden cones. I'm realy like it - sounding very good.
I don't think anybody suggested it was.
Nobody has. Your website is not under discussion to the best of my knowledge; just some of the drive units you happen to describe / list.
I'm not disagreeing that they're similar to the Fostex drive units, my point is what else would you expect them to look like? If an OEM brand is producing something to rival a Fostex drive unit, it will by definition be quite similar to the aforementioned Fostex drive unit. 'Copied' doesn't mean 'similar to', it means 'copied.' Unless they are using the same components, or components built to the same specification, it cannot be a copy. In this 4in driver's case, a quick glance at the spec. sheet demonstrates it to be rather different from its nearest Fostex equivalent (the defunct FE107E, per its own spec. sheet). Qt and Vas are higher, it has ~2.5x the linear displacement, a lower Fs, less motor-power, & lower efficiency. That's not a copy, it's a different drive unit, and will need to be employed in a different way.

I like white cones... I also like black cones.
I like bamboo cones and banana cones too. Wonder what strawberry, orange and blueberry cones would sound like?

and crocodile penis shouldn't sound wrong, but you 've stretch it a little. it's funny and good idea, but should you'll test it by analyser, Klippel, or same - you'll see the difference. not just visible - you can even feel it youself. and finaly - get reason to choose.

If it's all the same to you, I'd rather not get that close to a crocodile, never mind feeling it's membrum virile. 🙄
it'd better feel good, 'cause I'm sure it would be one of the last things you experienced (at least in this realm) 😱
of course who knows how the croc might enjoy it
let's get back to the regularly scheduled program ....
