I'm not sure which setting to set these at so here they are. Polk Tsi 400s for fronts,Polk CS10 for center,Polk Tao 100s for rears and Polk PSW 12 for sub. I have them running off my Pioneer VSX 823 K receiver. Im not sure what to set them at small or large and what level should my low pass be set on the sub? Any help thanks
