I'm trying to use REW and a digital RS meter to measure my sub output. I've loaded the cal. file and it doesn't seem to change the measurement at all loaded or unloaded, it does however give me another line on the graph (mic/cal line) that drops off from the target line as the hz drop, another forum told me to follow the target line anyway... is this true or is the black mic/cal the target with the cal. added to it.... it other words if i want the target i need to follow the cal. line. And also if the line does offset it self in relation to the target...will it automatically adjust if i load a house curve as target?
