This block of four picks up 2.5dB at 50hz (graph from EAW KF940).
 
Of course the stack will handle 6dB more power too, so a stack of four with four times as much power can play almost twice as loud (8.5dB).
 
 


You have just got to love that EAW document, marketing people had a field day.
116dB half space, but 'To achieve specified performance, the listed external signal processing with EAW-provided settings is required'

Appreciated djk, but maybe not fair to say that all horns will exhibit the same trend as shown by the plot you posted.

 

A horn with a vastly under sized mouth will to varying degrees make up for the short fall when many are coupled or the radiating conditions change. Also horn length will play its part in the final gain of added enclosures.

Rus,
 
A fairly tight driver will work well in those Z bins.
 
Aim for a Vas of around 180L and a Qts of around 0.3
 
A higher QMS > 9 will also help here.
 
The big question here is.......... should I have put a wink after the line above.

That is a single bin measurement though k.
