As a general warning, the graph on that page is incorrect. The Japanese distributor appears to have accidentally attached the wrong name to that graph (which is not for that drive unit) on his blog.

Scott, Stefan, are there spec sheets for these new drivers - or any others - ready for official prime time release? I’ve seen something for the PHD that differs from the FR curve posted by sk971 above, and that in the link in my own prior post. Too many cooks?
Freddi - that’s probably one of the data points that would be nice to see on a table of comparative specs for all models in each weight range.
Keep in mind that the type and shape of conducting material in the voice coil is only one of many constituent parts/materials that can tailor the net sound of the drivers - hell, even the amount and stiffness of adhesive attaching the dust cap to the main cone can matter.
I think the Seven PHD will sound very much like its intended market wants, and not only due the cone being paper rather than metal alloy.

That looks more like the correct data. AFAIK it was largely created by (and for) a number of Japanese enthusiasts with quite specific requirements, so is more of a specialist interest unit for its target market rather than for general appeal.
Glad they are continuing with a conventional surround+spider suspension for those of us who wonder about longevity.
Hi Chris
Here is someones test of the 7phd in which he comments it doesn’t match the graph he had seen , at least that’s what I get from the translation ( which can be quite unreliable , often talking about bile ????) . Looks perhaps llike a CHP70.2 but less extreme shelving.

I have both pairs 10.3m and 11ms now. it's easy to write about strengths of 11ms, but there are negative sides for me. 11ms sounds a bit more "thin" and "dry" then 10.3m. less ...magic.
@V0x can you share any more details or info. Is the box comparable (and what is it?).
From what we found comparing the 7-7ms, was a bit more distortion (no spider?) and slightly less power handling (cone shape?). I wonder if there is any correlation with the 10-11ms.

I am comparing pairs 11ms and 10.3m now on small primitive plywood panels without boxes (still looking for plans). All drivers were warmed up. 10.3 about 150hrs, 11ms about 20hrs.
I think these "a bit thin and dry" for reason of lower distortions of new driver.
To be fair 11ms have much more advantages. Better resolution, more spacious soundstage, better separation of sounds, bigger images size, it rocks with excellent dynamic. And more "open" (in your face) sound i don't know how good or bad it is depends on your system and preferences.

In the photo it looks like the voice coil diameter is larger on the MS11. Looking at the specs for both drivers there is no VC dia stated.

As I recall it will be (speaking off the top of my head as I'm not at home and don't have any data sheets to hand), but then, the 11 is about 25% larger than the 10.
OK, how can I get my hands on a pair of 7PHD??? I might still have some Navy buddies living in Japan; is that the ONLY place they are available? I love my 7P's (modified by cone doping) but, of course, they are not perfect. I keep saying and hoping I'd love to see a second generation Alpair 7P or maybe a totally new driver; an Alpair "8P" or something along those lines. I tend to prefer paper cones over metal or other materials as a general rule.
AFAIK the 7P-HD has an overall frequency / amplitude response akin to the CHP70.2 and completely different to the Alpair 7P; it was designed for the Asian market, and largely voiced by the Japanese distributor and a number of his key buyers to suit their specific requirements. These may not suit what other people want though.

Send me an email. These will be rare outside of Japan after the rest of the world got a taste of this flavour with the CHN-70

Just a couple of photos to add some meat to the bone of some of the discussion above.
These just arrived today. The first sample drivers for the new Pluvia 7 HD, Pluvia 7 PHD, Alpair 5.3 and the CHN50. I'm looking forward to all of them but am actually most excited about the CHN50. It should be really cheap and as it is so small could easily be used in line array projects. We don't see too many of those as lots of drivers quickly gets expensive. I should be able to keep the costs of these low though. I'd expect the first deliveries in about 2 months all being well. We probably won't stock the PHD for reasons discussed above unless folk really insist.

An externally hosted image should be here but it was not working when we last tested it.

Glad to know you have these (my) having just now learned they existed; can't wait for the reports! The Pluvia 7P-HD really has me curious. Again; I need to have a super-tweeter always so if it rolls off even starting at 5 KHz; that won't bother me one bit.
The same set is awaiting me at the Post Office (A5.3 by a different route).
The CHN50 would be even more insteresting with a rectanglar frame that would allow closer spacing and mounting on a set of parallel rails. Imagine a stack of 25.
