Dual Subwoofer Placement

To those asking about my setup, I will be setting up two Martin Logan 1100X subwoofers with a pair of Martin Logan ESL 9’s. I’m estimating my crossover will be around 60-80Hz. I have about 10’ from where the speakers and subwoofers will be placed to the listening position (longer if I measured at the actual angle from the placement to the seats). The room is approximately 30’ wide

WOW! I really appreciate the detailed response. Unfortunately, I live in an apartment and don't have the space to go with four subs, my neighbors will already hate me having two. I was in the process of getting a house, and then setting up my equipment, but that has since gone out the window and now I'm trying to make the best out of a bad situation. Not having the correct spacing for everything definitely makes it a little difficult but, if done correctly, I think I can still turn the space I do have into a solid listening stage, thus why I am asking for experienced feedback while trying to plan out my own layout. Again, thank you for taking the time to offer your advice.
