Nipper1 mentioned a tacky adhesive treatment, would have live in a completely dust free environment, or they would start to look awful after some time.
Fortunately, the cones are the color of dust ha ha! I really wanted to dope the back side of the cone but that's not an easy thing to do; small, tight geometry. This is the same tacky adhesive they use on cloth pleated woofer surrounds and some linen or other "cloth" dome tweeters. It really did clean-up the sound so well worth the effort. I'm glad to see the new Pluvia 7 P HD; it appears this newest design may "fix" all of my concerns and complaints about the Alpair 7P. I'll find out eventually as I am going to get a pair of the P7PHD's .
What the hell. If we could get inter-hemisphere shipping sorted, or find some other creative solution for delivery to the UK antipode, I'm happy to sign up for 50X.
NZ, give or take a few nautical miles. If a group buy actually started to look viable, I could come up with alternative delivery locations in US or Taiwan. While I doubt we can get numbers, I'm serious about the prospect.
Nor me, I've just been stacked out with work. I'll try and build some Frugel-horns for the Pluvia 7P/HD next week. I've not figured out what to do with the little CHN 50 yet
I am going to put the CHN-50 into a set of uMar-KenPlus flat-paks i have.
Stefan, you might get a mail from a fellow in NL looking for FH3 for a set of Coral Holey baskets.

They'll go in FHL too of course.
Cheers Dave, I can't seem to see the dims for those drivers anywhere. You got a link or a document?
Vintage Coral driver from the Japanese era of the generic 4” FR.
I think i have some downstairs.

It might be hard to make look nice without painting but I always thought the FH's could have drop in flush baffles for specific drivers, same CNC cabinet, but you just buy the baffle cutout you need, would make swapping drivers over a bit easier.
I did look at that at one point but it was a bit of a pain. Still might have another go at some point.
We shipped some FH3 with removable baffles, and all the FH-Lite flat-paks we did. I have a client that didn’t like the look of an sB so made the add-on baffle full height.

I am also running CHR-70s OB with a Goldwood 10 inch "OEM" as a helper woofer. I had to pad the MA down some to match the woofer's lower efficiency but I think it sounds really nice in this application. I am considering some sort of Alpair 7 for another project (sealed or possibly PR) largely as a result of my experience with the CHRs. I just need to figure out which version is the most apropos.
