I am thinking to add a subwoofer to my system and played around with REW to figure out best placing of subwoofer(s) in my room. I found that the best location would be center on the back wall and a second center front would help but not by much. I think all these simulations assume a pressure driven subwoofer design (my preference for that would be closed). I am also intrigued by the Ripol subwoofer design after reading about it almost 3 decades ago but never heard one. I understand in contrast to standard subwoofers which act as a monopole Ripol design has a semi cardioid pattern so normal subwoofer placement advice maybe not applicable. I did not find any good advice on Ripol placement even by the few companies which produce variants commercially. More design discussions I find here but in the pictures I see the placement is close to the wall and main speakers but I am thinking there should be a relationship between the out of phase back wave and wall reflection.
So I would appreciate any insight into Ripol placement and interactions with room and main speakers (mine are on wall design).

Forget ripole. Its too much filtering, eq required. Build proper closed box with proper woofer, lots of bracing inside.
Best way to find sub placement is to place the sub in the listening position first. Than move around the room and listen where it sounds best. Place it there.
