From the scope plot there's still some kind of EQ curve being applied, i.e. the kind of effect that gets labelled "rock" or "jazz" or some such.

How does this look for a sound card calibration? Tom

What are the two lines?

Would rather see the graph from 0Hz-20000Hz after you do the calibration with the small axis...

I think I've got it. I was about to call it quits last night so I waited till this morning to try it again. I got a flat line for my sound card calibration and did a measurement of the sub under the desk for the computer. I hope this is what it is supposed to look like. Tom

Good.....

Yep, except for a couple of suggestions.

Use the standard graph axis we all use here of vertical=45dB-105dB and horizontal=15Hz-200Hz. These values are entered into the Graph Axis button popup and recalled at any time to return the graph to these standard value.

When you measure a sub, you do it with the mains turned off and the crossover turned on so it will match that target line on the graph (hopefully).

Calibrate the REW target to 75dB when you measure.
