Hi All,

I just got new speakers and was measuring both to make sure they were all okay and equal. During the sweep of the left speaker I heard a rattle as the sweep began. I swapped out the right speaker at the same location and same amp channel and there was no rattle.

After some research I found that the stand's uneven legs were causing it. (I had kept the speakers on the same stands and swapped out the whole set).

I do however want to make sure that there aren't any minor rattles, resonances or vibrations still happening that I can cure and want to know how such aberrations could be traced and found using REW? Any input would oblige please. (the more detailed instruction the better).

Also, for convenience I have doing measurements from files I created in REW and streaming them to my WiiM Pro from a Plex server on a MacBook Air. Would there be any advantage in accuracy in running a cable to the amp from the MacBook Air earphone socket. Any input would really oblige.

Thanks!

On the signal generator Sine panel there is a "Frequency tracks cursor" box. If you select that you can set the generator playing and drag the cursor along the graph to change the frequency, that lets you explore the frequency range to see if there are any odd behaviours.

Measuring from file is fine and avoids any issues with electrical noise pickup you might encounter using a wired connection.
