I started a thread a while back with similar concerns, and opinions were all over the place, as it seems they are here.
Most opinions were against the notion that phase and time were important when setting up a sub, or multiple subs for 2-channel music.
All I can say is that I’ve had the opposite experience using subs with my Dunlavy speakers. I’m guessing this thread will morph into a discussion about using multiple (4) subs in a ‘swarm’ arrangement, as the panacea for most bass evils, and I accept that in principle the swarm should work well. But I haven’t had any success with it in my system and still prefer a single sub placed with attention to phase and time integration to multiple subs placed with the golden ratio principle.
I wrote about this experience in more detail here https://audioresurgence.com/2020/02/subwoofer-swarm-with-aerial-sw-12s.html
Good luck OP!
