With all this talk of architecture and now stainless and other metal boxes do we have some budding Frank Gehrys on the forum? Might make some interesting open baffles if he was involved!!!!

Thanks for that Aengus, I do periodically get my chemical abreviations wrong, weve had some interesting quotes at work, as you can imagine.

Formica is providing laminates with textured metal surfaces:

I have a sample #4788 called Matte Aluminum Dots II. The dots are convex. I wonder about any positive effect on diffraction.

I was going to use Laminex's ragged copper for some cabinets, then I found out the price was $300 per square metre, not per 1200 by 2400 sheet. Real metal is cheaper.
You could use punched steel screen to get the golf-ball effect.

Some interesting laminates, I'll have a look at UK prices.
Right back to the build.
Fistly filling the voids behind the deflectors with foam. The voids are covered with some hardboard tempory covers to contrain
the foam so it fills all the gaps and increases its final density a bit, also act as a pressure release valve. I'd rather do it
this way when I can control the volume and pressue instead of when the sides are glues on, as this stuff can be vicious.

The final lining scheme, after a few variations, this seemed to give the best effects. The holey braces are lined both sides with the light wieght wadding, a method described by Dave (Planet10) on another thread (sorry cant remember where) where as the wadding with the holes absorb higher frequencys. (not the best description)

It wasn't till I took these photo's that I got a real
appreciation of how large these baby's are. I've always been
close up working on them and have never realy sat back and
looked at them as a whole unit, then when taking these shots
my beloved walked past the speaker, and seeing how the speaker loomed over her, put into focus the size. (That and the collective hernia's I,m developing carrying them in and out of the house).
So now the fun part, finishing. I am tempted to veneer the hour glass shapes on the sides, double bookmatched, ie mirrored both horizontally and vertically around the centre lines, the more I look at it the more I want to do it, its just cost of veneer.

Forgot to mention, I've wired it up using 4 twisted pairs of CAT5 cable, after much deliberation, this gives me the most scope for trying different schemes and different wiring combinations, when (if) i reach a final scheme I can get rid of any excess runs.
Wowie zowie! The Curvey Chang is a very cool design. Where else can you find a speaker of that size, design and performance for less than $5k or more commercially. Great job!

Yea very nice design! Has anyone compare it with a BIB?
Or there is not a complete version yet?

I actually see very little reason to square the upper and lower rear deflector panels.
Its bacially a BR port firing into an expansion. If you needed extra support then vertical stringers would work.
As far as looks ( i am NOT qualified in this subject), i think just following the 45 degree angle on the cab sides and building a floor standoff with a supporting platform would look better and be an easier build.
At least thats the way i would do it.

Like this Ron?

Or do you mean make it 14 inches taller delete the top and bottom panels so the 45 degree panel meets the floor at the front edge?
Gychang built the uncurved version with a Pioneer driver. Sounds good but no measurements. Marce, you should put something on it for scale, a soft drink can, coffee cup or something similarly recognisable.

Thats what i am talking about. It appears to be a much more "friendly " design. You dont have to make it taller.
What i see in in room waveform sims is a directly centered response thru the bass reigons thru the upper frequency regions.The whole point is actual positioning of the LF wave in relation to the mids and upper. Its a balance that is not afforded by having a singular mouth, but having the beam spread gradually reduce as the frequency increases, but it is coming from a ever reducing area as the frequency increases, so its a singular point, or the effect of a singular point thru the frequency spectrum.

Hi All,
was thinking there's nothing to realy get a referance of size, will sort that this weekend, should hopefuly have a pic of both fully glued up, and some undercoat on.

Hi Ron and Mike
In think that one of the things about the design Scott and yourself Ron, have created, is its versitilty
it can be tweeked to fit with almost any style of design. The combination of a sweeping curve with angular
features means you can feature one over the other or both equaly to tailor the CC to your own tastes.
Its bringing out the artist in people, and I for one am looking forward to future interpitations of the
design.
I was pondering on the styling possibilites of the basic design of the Curvey Chang and the Turner prize
for contempory art last night, (dont drink cider Kids!) and thought that instead of the usual collection
of bisected calves or piles of rubbish, a ring of Curvey Changs (representing different aspects of contempory
design styles) focued on a central circular seat, would be quite cool, each could be wired up to a PC,
and thus the sounfield could be controlled.
Ed, Had a lokk at some of that formica, very nice but between £150-200 per sheet.
