what's up guys perry from rockville here and today i'm going to teach you how to set up your apm 10 active studio subwoofer this is the perfect sub to hear all those low end frequencies in your studio setup now the apm 10 comes in three different colors black like we have right here white and a classic wood finish so along with the sub itself you'll also get an included power cable to power this up now before i show you how to set it up let me show you all the different features on the subwoofer starting with the volume knob over here this is what you would use to set the level coming out of the sub underneath that we have the low pass frequency knob which will let you set the specific frequency range coming out of the subwoofer underneath that we have our face switch here which will delay the incoming signal to the sub over a range of zero to 180 degrees to better integrate the sub wit
