Do you mean delay between different subs of 40/50 ms? If the difference in distance between map and the subs is a couple meters, it would normally be 3ms give or take.



You’re comparing rew generated filters vs mso? Another approach I’ve been trying is just set the delays and run audyssey. It can do pretty well, not as good as a good pre-eq but surprised me. It gets the delays wrong a lot with subs. If you have two channel output on avr then it will eq separately but even so it gets the distance wrong, maybe due to reflections I’m not sure. Tweaking the distance post audyssey using rew pays off here.



When you use one output from avr for subs with different distance audyssey definitely gets confused, I usually set it after and then do delay (before and post audyssey) in minidsp. I don’t know if any of that really answers you but it’s thoughts based on what you said.
