I've allready read some of it. I read a norwegain guide as well, I downloaded the calibration file for my radioshack and checked the c-weighting box, but It didn't help much. I tryed again and set the start at 0hz. The graph shows that my fronts has a peak effekt at about 20hz
But why is the meter on the radioshack's screen jumping up and down when playing a rising tone from 0hz to 500hz? Shoudn't it be rather evenly rising? It's because of this I don't believe that this has anything to do with the software settings.
