If you encounter an issue with measured distance between speakers during the measurement process, this guide provides tips on what to check for a successful measure process.
In this article:

- Direct monitoring

Fine-tuning the distance manually after measuring
The distance can also be adjusted manually, after taking the initial measurements. If the inaccuracy in the measured distance is less than 20 cm (~8 inches), this can be easily fixed by adjusting the distance by entering the correct value.
If the measured distance exceeds the actual distance of your speakers by more than 10 cm (~4 inches) then you should repeat the measurement and make sure that the direct monitoring is turned off (your microphone input isn’t routed directly to your audio interface outputs).
For more information on this, please refer to this article.
Microphone distance from speaker drivers
If the software has measured the distance between the speakers incorrectly (error margin exceeds 10 cm), please make sure that you hold the microphone close to the midrange driver. It is recommended to hold the microphone 1-2 cm (less than an inch) from the driver.
Problems with additional hardware in the chain
When measuring your speakers, we recommend removing anything unnecessary from the audio chain to avoid affecting the signal or potentially adding latency to it. After the measuring is done and the calibration profile is created, you can revert to your previous setup. If this is not possible, please make sure that if anything is between your audio interface and speakers (monitor controllers, mixer, etc.) that the signal is correctly routed to the Left and Right channels and is not affected by tone controls, phase reverse, mono switch, etc.
Correct stereo image (panning)
Same as with analog signal, if your audio interface has a control software, make sure your speaker output channels are correctly routed in the software, panned fully to left and right channels, and are not altered by any DSP processing if your audio interface has native DSP effects.
Problematic room modes
Sometimes the precision of the measurements can be affected by unordinary reflection in your room. The standard microphone locating signals are set to 1 kHz - if this frequency is particularly problematic in your room, try using the B and C locating signals available in the speaker measurement software Settings.
