Location of speakers in the room in relation to your listening position will have the biggest impact on volume of each speaker. Same answer though, use REW signal generator, level of each speaker can be set independently in the miniDSP, or use the volume balance slider in the Wiim Pro config...

Need more information. What is the "stereo system"? How is EQ being implemented? Usually speaker level and EQ can be adjusted independently. For example on an AVR, you would simply implement the EQ, then use the SPL meter at listening location to adjust the level of each speaker, most AVRs have...

For anyone interested, I reviewed the J-Box III speaker measurement system here a little while back: https://www.htguide.com/forum/missi...ment-tools-techniques/957531-j-box-iii-review This is a great piece of kit, providing the means of completing impedance measurement and acoustic measurement...

John is quite right, amplifiers that used a bridged output cannot be used with this type of measurement jig. Easy check would be to run output from your audio interface directly to the amp, turn on the Generator in REW with 60Hz size wave. Check the amp output terminals with a multimeter, from...

Why?

I don't see anything changed.

My car makes a noise, what's wrong with it? What is your sound card / audio interface? What have you configured in the measurement window? Are you using EXCL device in REW preferences? Share a MDAT file of a measurement? There's not much to go on with what you've provided.

Amplitude16 is a power amp, what's the audio interface between your computer and the amp?

Try the overlays window.

I use a Motu M4 and Line Audio Omni1 for my measurements. If you already have a nice USB audio interface, why are you looking at USB mics? For design a loudspeaker, it involves combining the response of multiple sources from multiple measurements, which requires accurate phase relationships...

I don't recommend usb mics either. I did just review the J-Box III, a great all in one speaker measurement kit to get started with speaker design, with a loopback timing reference. https://www.htguide.com/forum/mission-possible-diy/development-tools-techniques/957531-j-box-iii-review

Thank you John. One other minor thing I noticed recently, is that the frequency limits noted on the measurement thumbnails have a limit of 20Hz min and 20kHz max, so they will show 20Hz-20kHz even if the measurement was completed from 0Hz to 48kHz for example.

Is there a possibility for a higher resolution for burst decay waterfall or spectrogram, like 1/12 oct bandwidth?

FireWire died years ago, go with USB interface if you want to be able to use it easily with any modern computer.
