I think sticking with Rule 6 is important, as one of the aims is to see what can be achieved with modern components and methods. If we set out to have something that won't go as loud as the original then we're losing our way. It would be good to have something that could be fairly compared with the original.

it will be better than the Gales, but the ultimate 8" for your size is Scan Rev.
I obviously agree on the Beyma but that Vifa TC9 only does 83dB 1W/1m and runs out of thermal power capacity at 97dB assuming no power compression.
Scan 12M Revelator midrange and Scan D3004-660000.
possible xover @380-500hz and @2500-3500hz.
But 12M does costs nearly twice as much as the 5" BMS I suggested and was dismissed as too expensive.
Similarly the D3004-66000 at £105 +VAT might be a tad too dear.
And again the 8" Revelators start at £163+VAT and none seem have a Qts high enough to work in a sealed cab.
A Scanspeak Revelator stuffed box would come to about £500 (Aus$ 910) per speaker without tax or postage.

As far as the cost of drivers is concerned, what is readily affordable for one DIYer may be out of reach of another. This is why I proposed that we eventually sort the drivers everyone suggests into 3 groups ("Phase I, Phase II or Phase III"). Personally, I'm unlikely to build a Phase III, but I don't wish to deter another person from doing so. When & if we get to constructing something, I'd like to see a build log from each group.

There are few reasons :
1. Available in Australia (through WES)
2. I've worked with 12M and heard the D3004 and Scan 8" Rev
3. None of the 8 can work within his volume limits without EQ, when we apply EQ, the power handling drops significantly, hence we need woofers with stronger motor and more xmax (have a look at my simulation)
this is the ultimate version of Gale inspired speakers. I'm pretty sure there are few dozens of combo out there.
Another GREAT candidate is
1. SB26STCN
2. SB15NRX
3. SB23NRX
with EQ, in room response prob go down to 30's. again i've worked and heard these drivers, and they are absolutely excellent for the price.

1. Fair enough as I obviously have no idea what's easily available in Oz.
2. I've no doubt that they are good drivers, just a bit on the steep side but as Brisso said 'Phase III' candidates.
3. According to MrMag and my own simulations the Beymas do 50Hz without eq using factory data.
The GS401 is a W-MT-W 1978 speaker. Awards
The Sony SS AR1 TM-WW is a 2011 speaker. Awards
A great exercise would be to compare the two designs using the same drivers. How much sound quality do you give up for style?
"1978 style layout" versus "2012 performance layout"
Absolutely nothing wrong soundwise in the original design and layout if used in the correct orientation so SQ is always my priority. Or have I misinterpreted your statement.question??
Brisso There are so many 2Ohm stable amps around these days I don't see the need to it being a dedicated Tri-amp speaker and would have liked the option of helping design a passive XO when the drivers were selected
Has anyone considered the middle of the range Vistaton 200mm woofer W-200-S??
Available in Australia and despite the Fs of 30hz and the Qts of 0.33 it should work reasonably well in a sealed box, even if the F10 is higher than absolutely desired

Thanks for pointing that out, yes it does look workable with or without EQ.
good price too 🙂

with EQ it won't have enough power handling to keep below its xmax.

Hi Moondog55
As far as designing a XO, you're very welcome to chime in as we go along. Perhaps we could have some (including myself) choosing to triamp, and others (including yourself) choosing to go "hard-wired". I don't see a problem in developing the two options.

Doug that's all I really need at the moment.
"Another" project LOL
Crikey it takes me ages to just overcome the inertia.
With regard to -henrys- objection how loud do these actually have to go?
10mm nominal X is actually quite a bit as X-damage is at least +15% on these woofers so how much low bass boost were you thinking of henry??

GS401a Chromed Stands
For anyone who may be interested, I found a reference to someone who has (in recent times) manufactured a number of replica chrome stands. The stands have been bought by many Gale enthusiasts whose Gales were not sold with the stands. (They were options.)
Anyway, here's the links

the xmax is 3.5mm 🙂
Visaton W200S-8 8" Woofer with Treated Paper Cone 8 Ohm
According to the Visaton website the W-200 is +/- 10mm and I'd say that was accurate from the one sample I handled
BTW that link is dead; at least with FF

its either the rating is for point to point, or its not linear xmax rating.
from PE specs :
3.5 mm of Xmax and a ±10 mm excursion limit means you can use this as a subwoofer
i can trust PE specs, as they are proven to be honest enough 🙂
