Birch plywood is excellent and not too expensive.
I'd avoid solid wood as it's less structurally stable.
Thank you for further clarifying your position and apologies if I unintentionally misrepresented your thought.
My intention was fundamentally to express agreement on the fact that system and crossover design are the more important factors.
I respectfully disagree that those psychoacoustic tests are conclusive enough on the matter.
But "close enough" for most (statistically speaking)... sure.
What CNC shop are you talking about? I have been looking for such thing for a while.
Randomly searching on Taobao that states 3D wood CNC capability.
There's at least 3 with short search last time so I think there's quite a few shops capable of doing the work.
Not sure how the final product quality would be though...
Btw, is there a lot of Taobao choice in Taiwan as well ? would be wize though to CNC local with local trees and local short distance transportation for some evident reasons.
I think shop in Taiwan seldom sell on Taobao. However I do try to find CNC shop / enclosure manufacturer here in Taiwan before.
Enclosure manufacturer that can do more complex shape has high quality...but the price is also much much higher compare to Taobao.
The CNC shop doesn't reply after first few conversation...
So I was surprised to find shop on Taobao that's willing to accept the order. But it seems this kind of shop (capable of 3D CNC) is quite occupied.
I ask as the beginning of May and the shop owner said the following 2 months is fully occupied. Let me to ask them 2 months later.

..China CNC:
1. Make sure the wood milled doesn’t use nasty glues.
2. Make sure that the shipping cost is reasonable for the project.
3. Make sure that their machines will accept your CAD file of choice and generate perfect g-code from that file.

Nothing is ever conclusive if you don't want to believe it. But suit yourself.
I agree with all that.
Having spent far more than the norm in China it was not always easy to deal with. But last year I had the chance to make a very large order of glass chandalers directly from China and once everything was clear on both ends (and that is certainly getting better) the prices, customer care and workmanship were all excellent. You just have to remember that things are not always understood in the same ways.
It took me a second to understand this, as I thought you were speaking of all compression drivers, but you mean the 4003, 2002 specifically. Right?
IME modern PA drivers, including compression, have mostly been pushing the power handling specs. Drivers handle so much more power than they use to. Does that make them sound better? Yes - better than a blown driver. 😛 But when not abused I haven't found a lot that sound better than good 1950s drivers.
Perhaps. But having heard lot of speakers, including yours, I have my doubts. A lot of people don't notice much - in audio as well as in general.
If anyone wishes to clone/approach Yamamoto Soundcraft's 1" horn (SS-300) which is used with the B&C DE500 in the YS-500 2 way (open back)...
Docali's 1" Neile horn is definitely a cheaper alternative and just as good, with wider dispersion > 90x40 versus 70x30.
Prototype with Faital HF108 (the horn has since undergone improvements):

Yup, no reason not to go with China as long as you get what you need at an overall good price unless it's something that's under (product category) a heavy import tariff.
Here's a strange import for me recently:
-looked around local and US for a good hobbyist welding table-top, cheapest *decent solution in the US was about $390 (including tax + shipping) and taking a couple of weeks to arrive. Checked International sources (China was a no-go because of shipping) and believe it or not I ended-up with a slightly thicker (better) top from England that was around $270 shipped AND it included my State's tax and currency conversion. Yeah, ENGLAND - and it arrived within 5 days. How can my local source with minimal shipping expenses be almost double the cost of what I can get from England, while also taking longer for me to get it?
*it's all about table-top thickness and bracing to achieve a flat surface that won't warp from the heat while also being thick enough for standard tool/clamp inserts; most of the cheap stuff is worthless cr@p.
-anyway, just a weird little tangent to this thread.
Lals uses customized drivers that are manufactured locally. According to a Chinese website, the diaphragm of the 1" is formed from ultra thin (0.02mm) titanium.
It's not about belief. It's all about the details and what the tests actually prove and what they don't.
