I was wondering if any horn designers could whip up a quick and dirty design ?
I wish to use 2 drivers as a center channel drivers in middle angled in abit tweeter in the center ...with the horn mouths on the right and left ... as the cabinet will be laying on its side underneath a tv.
Dimentions are 29"x 16.5"x 6.5"

I was hoping to have it "port A11 tweeter A11 port" [] OoO []

is this a doable configuration or will the cancelation be a factor

thanks for helping if you do I never have had any luck with the hornresponse program Im not very good at numbers I guess so im asking for some help here.
