I suspect that some setting in the receiver or sound card or windows is cutting off the low frequencies if the right channel and left channel are running together. On the Soundcard page, the output and input devices should look like this. Another reason is poor contact in the microphone-sound...

To figure out how the subs interact with each other and the subs with the main speakers, you must take measurements of each participant in the sound creation separately and synchronize them in time with a loopback, or acoustic reference source. The second option is simpler. Because this...

If you are analyzing excess group delay. In your example, it is not clear which group delay graph is shown.

I didn't have this card. Looking at the specifications, it should be enough.

Better yet, don't use an amplifier. For any purpose related to impedance measurement, an external sound card with 2 inputs and 2 mid-level outputs is sufficient.

In the measurement window on the right, in the options, try using one of the last two lines.

FSAF file length is 35 MB. The delay appears with all three tabs with which REW was closed. But on the SPL and Impedance tab there is no delay indicator; a small window appears and disappears very quickly, the text of which is not visible. There is a delay indicator on the FSAF tab; it starts to...

Settings for three tabs.

This only happens the first time after running REW. All subsequent openings of the slowdown window are not present. Should I take screenshots of the settings of the three tabs?

There was once an issue that the measurement window took a long time to load due to the FSAF setting, even if the FSAF tab was not used. In the latest versions, the measurement window does not allow me to do anything for 10 seconds after opening. Similar to what it was before.

The level in the Measure window and in the Preferences window was -9.7. I installed them before calibration. Just in case, there is a video.

John, after the second impedance calibration step, the level value becomes -3.01 dB. Although before that I set -9.7 dB in the measurement window, and took the first calibration step.

I thought the same thing. Listen carefully when the sweep sounds. If you specified in REW that the sweep should be from one channel, for example, L, somehow the sweep goes to both L and R. The receiver may be doing this because it is performing some kind of setting that is not disabled. Windows...

In beta 113, the display is correct in this place. But elsewhere it is wrong (In beta 118, the display is correct in this place.).

Wrong in both cases, with EXCL and without EXCL.
