I would double check your data inputted into abec, it predicts better, but also is very unforgiving, if your data entered is slightly off...
 
it also looks like some sort of cancelation is going on.
 
there is a small closed group I belong to on fb, were only abec is discussed, and we share open ideas. and problem solve.

In akakak you have set the drivers position, and in general the Physical dimensions and positions of the elements in the box? ... maybe you did not consider some refractions .. i use comsol integrated with inventor to have no doubts regarding geometries
Anywai abec3 is a vary  great simulator, especially from those who like me come from akabak

ps:since you're using a good 3D model, you may already analyze a phase plug so ridice the front volume of the mid-woofers and increase the top respose and control the directivity  .... or  you use a coaxial driver?
