i did my big 3 and lost my settings. i need to set the Q factor for various hz.low is 40-80-100-160.my options are 2N-1N-1W-2W.what do these stand for and which gives higher output at any given volume.before the big 3 my bass was heavy and full at all volumes now i cant hear it w/out uping the bass on the amp or using the loud button.i think this is the problem (q factor)wich is more toward quality and which is more toward sq for any given frequency?the 4 choices again are 2N-1N-1W-2W.CAN CHOOSEany 1 of the 4 for 40hz 80hz 100hz and160hz.thanks for the help .
