nooo... they all fire into a central point and then out of the port facing you using the two horns as 1 big horn.
If it sounds like a gorilla is trying to escape, turn it down.

a bit like the 70's trouser flapping design but...... the back two now have a longer horn path. To get this to work all 4 horn paths would need to be the same length, and all four cabs would need there own horn not shared. It would work by allowing all four to couple once the sound has left the box....

well, wots done is done... get your measuring gear out and lets see what youve created Dr Frankinstien. and if you can delay those front two cab just a tiny tiny amount... theres only a few cm's in it but im sure it will make a difference.

Defo delay will be needed. Not sure how to rescue this one other than using electronics

i recon a tiny amount of delay will "cure" most problems.... just hook it all up and give it a bit of real-world testing and tweaking. but as on AB test stack 4 ES's beside it mouth coupled and listern for any difference in depth/punch...sorry kick... and play with the bandwidth a little too. you never know it may cure honkyness from being played to high. either way you already got the foreplay out the way you might as well go balls deep and see what its capable of!

Which will at least have the positive effect of making it easier to decide on throwing whats left of the cabs out 

To the O/P do you mind if i ask,  what are the other speakers in your setup? not sure if its just how there stacked or a trick of the lens but the left part of that wall and the ones on the top of the right stack look like they also have chopped fronts or a spikey bit sticking out? sorry not sure exactly how to explain that. Just wondered if thats so and are they your design?
