I sense Keryn's frustration.
It's quite one thing for a website to say they stock or can stock xyz thickness ply, quite another for it to be in stock, at a reasonable/justifiable price.
Even after calling.
Even though a good chunk of ply in Australia is locally made and manufactured.

Most of the links you posted up are for Sydney or Melbourne stockists, 11 hours and 17 hours each way from Keryn's home town.

I've not been able to find full sheets of 12mm or 1/2" ply with 5 equal thickness radiata plies less than 8 hours each way from my home for years now.
There is 12mm ply available to me locally, but it's hardwood in the centre 5 plies, and 2 thin dress faces, which of course in unacceptable...

What a bummer.

Keryn, let us know what you end up doing. Whether it be finding an acceptable substitute material, finding a local (enough) source of the spec material, or the road trip solution. I thought I saw a couple of the links offered shipping options. But, I wouldn't bet more than a dollar that I actually saw what I thought I saw. LOL

Best of luck!

Thank you for your efforts Seth, I retracted the post after an hour or so as I was called back by a Yard at the Gold Coast (Mister Ply, 40 minutes away) who can supply 7mm Bendy Ply, however it's full sheet only purchase at $264 , I'll take what I can find, thanks again mate.

One yard was certain they had 6mm 3ply, so over I go.. turns out they had 6mm and 3 ply, but they were two different sheets

Good morning Lads,
In consideration to weight savings, these Neo Faital Pros are available locally at $400AU each, I feel confident they're an equivalent to the Delta Pro 12s, however I'd like to check as the site is listing them as a LF driver.

Eminence Delta Pro 12

I appreciate your time, thank you in advance

What are you wanting to put them in, Keryn? DR280?

Yes mate

The way I see it, both drivers are pretty similar specs wise.
I'm not sure if it's a prob for the Faital Pro, but Vas is higher.
And the Delta Pro 12A has higher power handling ability. Don't know why.

The most glaring difference is the rising response above 2K for the Eminence Pro, and that's lacking in the Faital Pro.
That should be kept in mind with the choice of melded or flat array which will have a 2K corner frequency in the filter for it, dropping response from 2.5K in the piezo's as noted in the plans...

Would the 12PR300 be better suited to the 1.2kHz HF horn option?

IMHO Yep.
As long as you can find similarly specced compression drivers in the plans that don't raise cab cost a lot.

I'd still want to know what between the Eminence and the Faital Pro means the Eminence has higher power handling before I jumped though...

Roger, down the rabbit hole I go again, I've given up worrying about the cost of similarly specced anything down here these days man!

That's way above my intelligence level mate, more yours & Seths realm, I'm still at cut, glue, solder..

Shoot, Keryn... I think you give both Grant and myself too much credit. We're all on the never ending audio learning bus together.

It seems a lot of the time, tops suffer distortion well before their rated power is reached. In any case, the difference between 300 and 400 (or 600 and 800) watts is an inaudible 1.3dB. So, the value or advantage is more than likely limited to thermal headroom. The minor Xmax and Vd differences are nearly inconsequential, 0.7dB. Honestly, if it get's Bill's nod for modeling well enough, I'd run them without a second thought. I think Grant may have a really good point about using the 1.2kHz tweeter, given it doesn't have quite the rise in midrange sensitivity of the Delta Pro 12, that the plans say is required.

Also, it may be listed as a LF driver, but with less than 5mm Xmax, it's not really something that would be used in a sub.
