Second, 18LW1400 is not a bad driver, it is pretty much same thing with the RCF 18P300 that is one of the recommended drivers for the Rog's scoop.
Now it is outdated for sure, but for a moderate spl job it should do just fine.

Hmmm, i dont see anything wrong with the box.
Maybe its the scoop sound that you are not use to.
As you can see almost everyone are using them with a kick box above.

I know and love the scoop sound. I am missing the pressure the kind that makes you want to run from the speaker.

Well I would have thought this would be a good indicator (Considered along with TS params)of power efficiency but it appears your saying its irrelevant, so it doesn't really matter that I thought that the PD was more sensitive but also its Irrelevant that the Void is, as it has to sit in its own specific design like all subs. As far as I know there's not many people that use Void in scoops.Cheers

Sensitivity is always averaged from the pass band way out of operational range. In most of the cases 100-500hz.
For subwoofers you need to look at other things.
QTS, VAS, BL X-max.
Heavier cone drivers will have more x-max and thus shift more air.
Will need more power, but that is not relevant because we are after the max spl, not the 1w spl.

The size of that throat is enormous man, and a strange up angle panel, imho

so its probably down to the design

i aware of the top heavyweight scoops buildwith large-ish throats

No solution Dub? Or suggestion of such? Patiently awaiting Lev's response.

I've got a few scoops/and I'm comparing and thinking the same as you Dub SP the up angle panel sits low it should be more acute this design will play low freq I cannot see how your going to have your cake and eat it. Will there be any consideration to bracing in the horn mouth, is their any reason why horn plans on here or others (established) minis weren't considered first
