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 .

Actually looking at this again and getting the factory to do some more maths I can get the MOQ down to 1000 which is more doable I guess. Price to the end user would look to be about $38-40 a pair. which is about £1100 for a pair of Dave's mock ups above. We'd need 18 people to make that doable.

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.

@Scott,

Is the nostromo(large) also doable with the port on the front?

 

[chrisb]

So, New Zealand, then?

So, New Zealand, then?

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.

Any listening impressions yet from Dave or Stefan of the new drivers?

 

[planet10]

Not me, i intend to, but 4 surgeries in 8 weeks is slowing me down.

Hang in there Dave and know your buddies are pulling for you,

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

 

[planet10]

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?

 

[planet10]

Vintage Coral driver from the Japanese era of the generic 4” FR.

I think i have some downstairs.

Thanks Dave, it would great to know the cutout dimensions before your guy got in touch.

 

[TimbreAudio]

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.

 

[orangeart]

I did look at that at one point but it was a bit of a pain. Still might have another go at some point.

 

[planet10]

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.

Yes, CHR-70 with Eminence Alpha 15a woofers. Lots of fun. I imagine the new drivers will do much better, but like other said, with helper woofers.

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.
