| Re: Why is a flat target response, curved in REW?
The target response is following the bass management curve of your processor, which is typically set to be -3dB at 80Hz and rolls off at 24dB/octave above that. When measuring the sub with the test signal fed via a processor that is the shape the response should have. You can set up REW to yur processor's actual settings using the cutoff control. If you measure with the sub and a main speaker playing, the overall response should then ideally be flat, and you should set the speaker type in REW to "full range".
