Did i say "throw"?
We were not talking about artillery, were we?
What i was talking about is the significant combination of high spl and strong directivity for which horns are generally capable of delivering percievably louder sound at a distance, rather than reflex cabs.

Did you manage to get any measurements of the siniai paraflex?

sorry for off topic...

Imho sbh is absolutely NOT the best bass horn design, on the contrary it can be one of the worst bass horns one can choose to build. It's massive, heavy as f***, tricky and expensive to build.. and the results doesn't pay back: it has a really uneven response, a big dip at 50hz (where most dance music basslines hit) that gets a bit better only with more than 6/8 cabs per stack.. it seems the designer tried to reach lower frequencies, but sacrifying the overall performance. No surprise they're mostly used in freepartyies, where sometimes sound quality isn't the primary goal, and even there most skilled crews get rid of them after some time. I wouldn't even compare it with the CV L36, which is an old commercial product but definitely performs better in its range (Cerwin Vega is STILL working on that old design for their cabs).
To be brutally honest, i understand you like the look of them, but speakers are made for hears, not for eyes.. well, even the back plays a big part so believe who said you can get much more from that air volume, and spare your time, money and backpain for a smarter design.

How many have you listened to? Or measured? It’s your money, wood and time, but myself and others would be looking elsewhere.

The Skram has very detailed plans here:

And it's quite forgiving on driver choice. Not technically a horn, but very optimised. Hornresp 'max SPL' plots are not trustworthy in general - it's a linear acoustics model, and has no idea about distortion thresholds or cone load - but here's an example of the response shape of various drivers at their Xmax limit:


Hornresp inputs are:

But make sure to use the complex semi inductance model. Click Le so it goes green, and put the data in, Google it for a guide on finding it from TS parameters.
