Hello everyone, newbie here, albeit a happy one!
Music only system (no AVR) with flex digital, 2 subs and 2 mains.
Question is: how to set up correct acoustic time reference measurements? For subs only  measurements, I choose L ref output in REW, high pass the L speaker as to not interfere with the subs and everything goes well! But how can I set time refyfor the right only speaker? Do I have to change the ref output to this speaker, and if so, will this be comparable to the left time reference? Thank you in advance for any input!

What I do is keep exactly the same acoustic timing reference for all measurements (e.g. left main speaker) and then adjust the signal routing so that the right channel can be used for each other speaker I want to measure in turn. I only have one sub so in my case it's just swapping if the right channel is the right main speaker or my sub.

Thank you very much for your reply. So how do you avoid measuring the Left speaker while doing measurement of the Right speaker? I guess that both outputs L & R must be active at the time of measurement!

You separately define which speaker is being measured and which is being used for the timing reference, like this:
