Measuring all speakers at once

[Snuff Daddy]

I don't understand why REW doesn't let you measure all speakers at once. This would be very useful for setting the receiver's crossovers, and achieving synergy with the subwoofer. For example, my front speakers are run full range. if I see a bump around 100 hz, that's an indication I can turn down the subwoofer's crossover to 80. But I don't know if that bump is there unless I measure the fronts and the sub at the same time.

REW doesn't allow this directly by design, but you can do it manually via combined measurement.

You might find REW’s alignment tool useful to help examine the response of subs and mains and the effects of delay and relative volume changes on it. Saves a lot of time vs trial and error. Requires that the sub(s) and mains are measured separately, with the XO you wish to examine in place. Also requires measurements to be done with a timing reference, either loopback or acoustic.
