REW measurement of 2.1 system - would you EQ and where/how?

[JohnPM]

The response looks typical of one where a measurement is being used as cal data. You have selected "Use loopback as cal and timing reference" but from your system description it doesn't look like there would be a way to have a loopback cable connected, which from your selections would need to go from the right output channel to the left input channel. You haven't made any device selections in REW, leaving them as the Windows defaults, so can't tell what you are using for output or input. If the input is a USB mic you can't use any loopback timing options.

Thank you, not sure how I managed it. Really frustrating thing is I get the chance to do this once in a blue moon.
