Kodomo, 
 
A brief post about concerns. Feel free to discard it. 
 
LF modules – are you sure that you want to go with ported solution? You can model your boxes and use any good drivers but sonically with port you will end up with bass that would hardly please you on a long run. In so many words – it is known that I am only for sealed or infinite baffle but that is me. Also the location of your bass channels. They need to be outside, not between your horns. You can very easy to test it yourself. I am sure that you will say that your room does not support it – well, welcome to the club of very many people…. Anyhow, do try finding a configuration when bass channels are outside of your main speakers. 
  
A large glass window behind the horns is a bitch. Deal with it somehow. Also, on the photograph the horn is sitting very close to the back wall. I know that it is contra- intuitive but this type of horn topology is super sensitive to the back walls. Try to move the horns for a good 5-6 foot toward to the center of the room and you will see how dramatically the sonic presentation will change.  BTW, if you move the horn for 6 foot forward then you will clear the entrance door and will be able to move your right channels all the way on the right… gaining more width and enabling to use bass channel to be outside the horns. 
 
More about the requirement of bass channel to be outside. If you did not make your boxes for bass then think again. The selection of TAD 1601b is fine but they are 16” that would require a front baffle to be at least 20”. If you go with smaller driver then you will be able to make narrower your front baffle. I understand that larger driver is better but this will be not sub 20Hz woofers but bass module that do 100Hz and they need to be geometrically at right position. The Supravox drive in the upper bass horn: introduce another crossover point at let say 60-80hz. There is no reason to have LF signal to bombard the driver if the horn will not produce it. Your sound from the upperbass will improve then. 
 
Ok, need to run to deal with baby. Sorry did not say anything positive, not because your setup does not desire but juts do not have time.
 
Rgs, Me
