Hi, I'm about to calibrate my SVS PB10.
But my sub starts humming if I turn on my spl meter. If I turn the spl meter to 80 db it hums so hard my ears almost pop.
I also have trouble calibrating the soundcard. If I measure and the sweeping sound comes it only measures about -78db fs. But almost whole my house depresurizes from the sweeping sound. is that to load or to quit?
I'm using the M-audio Delta 44 soundcard btw.
