Yeah it' very similar but I'm a lil bit confused with hornresp since I'm new at it so I was wondering if to just try building one and see how it goes but more work also..
Each driver has the recomm. volume and port size for a bass reflex ,I am not sure if it will work positioned like this to minimize distortion.

ah, a strange kind of "ripole"
mind you
its pro sound "subwoofer"
doesnt go so low, but instead louder
not really a domestic hifi thing
more in the party disco techno direction

look up ripole, which is a folded dipole

another "variations" is H-frame

plenty info on those

That zip file is damaged.

Anyway, it's only a horn above 100hz, probably has a nice peak between 150hz~200hz.

"Thanks,but I need translation,haha"

You didn't give a port dimension in your first post. I figured it out for you, 10-5/8" tall, 3" wide, by 8-1/2" deep.

Use a 40hz high-pass filter, with a Q=1 if adjustable.
