I have made measurments of the left and right channel (With left being the time reference output) in REW to time align the two speakers (I have some imaging problems)

The problem is that the 'System Delay' off my time reference channel (Left) is not zero, so I'm a little bit confused.

From what I have been reading the System delay is relative to the reference, so the system delay here should be zero and the right channel should be negative or positive delay/distance.


This is the system delay of the right channel (left as timing reference).

What could be going wrong?

The documentation on REW website says that For speakers the delay estimate is based on the location of the peak of the impulse response.

Considering that my speakers are 3-way speakers, could it be that the peak impulse response happened at the subwoofer instead of the tweeter (The driver from which acoustic time reference is played)?

Considering the data i provided, what should be the delay between the two speakers?
