The measurements are almost the same. There are no obvious signs of defects of one of them. They both have a problem with HF. You must listen. If you don't like something in their sound, to understand. Measurements can show something, but may not show any problems.

BL and MMS almost coincide with factory parameters. What can affect the mismatch of other parameters is an inaccurate measurement of added masses (you need accurate scales with two signs after comma), too high measurement voltage (the dotted lines of the model on the peaks of impedances do not...

You must meet all the measurement conditions that the manufacturer had in order to get the same results. You won"t even be able to know about it. But it is possible to get similar results. For example, if the manufacturer has Qts 0.33, you can get 0.39, or 0.42. Try changing the sensitive...

In my screenshot, your measurement of the Y-519I-R was delayed by 6 ms regarding your measurement X-R. At your screenshot, all measurements at one time point. If all 4 measurements are Main+Sub, then nothing can be appreciated. There must be separate Main and Sub measurements to understand what...

It is not visible. All 4 graphs seem to be the same in delay.

TFL can be moved to the right by 3.5 cm, and C to the left by 3.5 cm. If the delays do not allow the speaker to be repositioned by a very small distance, it is possible to physically move the speaker. The peak of the sub"s impuls will be slightly shifted from the rest. It seems that on your...

I looked. For L, R, you need to install a delay of 4.83 m, or 15 ft 10.2 In. As for the side and rear, we will look at them later. At the same time, there is a small problem on the 35-60 Herz section, so it’s better to try 3 or 4 order of the filters. At a frequency of 75 Hz. This is the average...

I did not quite understand. You should work for some time in REW, each time listening to what happened. If the final result does not suit you, publish the MDAT file with measurements with acoustic synchronization of all your speakers. I will see which delays are better suited.

If you hover over Ref, the vertical line will indicate the time of the maximum peak. In your case, Ref indicates a negative peak. Align with positive peaks. It happens that Ref indicates a positive peak. There are impuls values at points on your chart, but there are no impuls values between...

To align the impulses, you should look at the peak of the impulse after the first rise of the graph from the zero level. Therefore, the highlight should start at one peak at the top of the zero level and end at the second peak at the top of the zero level. If you have multiple acoustically...

Usually, to determine the time of the shift of the impulse graph of one speaker relative to the other, it is better to open both graphs in overlays->Impulse. The goal is the match of the positive peaks of the impulses.

I was referring to the way this line is written: "Sensitivity -12.34 dBFS". Now everything is clear to me. Thank you.

Thank you. Do you have an example of correctly designing this line in Cal File?

If I know Full Scale SPL, is it possible to specify this in the microphone correction file, as the sensitivity is indicated?

Thank you. I double-checked the files, now everything is as it should be.
