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.
dave
Yeah, maybe, although the square frame is a bit of a pain for those without a CNC machine or a good set of router guides. The frame is actually quite thin so C2C will be pretty reasonable. I've been meaning to build a line array for ages so will hopefully find the time this year.
:^)
You haven’t thot about it enuff Stefan.
A rectangular frame, not square. Take 2 spaced rails, ply would be easy, aluminum would mean tapping 200 holes. Taking care to use lots of closed cel gasket strip, just start screwing the drivers between the rails. Use thinner tape folded over the inside-horizontal baskets joins. Plug that into as elaborate a cabinet as you’d like.
In a line arrary centre-to-centre the smaller the better.

I might be mistaken, but I doubt that will happen. AFAIK this driver utilises an existing basket. I don't think they've got the money to create a brand new square basket specifically for this purpose; the tooling costs would likely wipe out what little profit would be made. I actually made the suggestion of arrays to them some months ago; they should be OK. Yes, square would allow slightly tighter spacing, but it's doable as-is.

Stefan,
Can you put a ruler across the CHN50? Diameter? 80mm?
dave
Dave, they are 102mm.
As Scott said the basket is from another model that was only in Japan that sold thousands, hence being able to make them so cheap as the tooling is paid for already.
Since you have it on an open baffle, any chance I can get you to drive it with a low frequency sine wave and let me know if it is buzzing or not?
Did it. I heard nothing similar to buzzing at 30-200hz on high volume.
Looking forward to hearing them all!
Do we have any indicative pricing?
Line array could be fun.
Not yet, I'll work it out over the next few weeks, no hurry, they will be a while on the slow boat from China

Been posted in various links several times so far. The one labelled P-HD (and the T/S data) is not to the best of my knowledge actually of that driver; the Japanese distributor seems to have made a mistake and published the wrong data set.
I found a dif. set of curves on the 7PHD on a Japanese site; I'll look again; I may have forgotten to book mark it. The HF started to roll-off at about 5 to 6 KHz as I remember which would better fit the intended market. I dig a little deeper later...
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.
Ugh, that spelling mistake. Next you know audiophools will insist that "definitation" is the new frontier of audio.
That CHN-50 looks cool for a small computer speaker too!
