0 Reply #11 · Jul 23, 2014 some threads just need aging, like fine wine.. #12 · Jul 23, 2014 lol, no kidding, didnt notice this was ultra-necro, lol. 0 Reply #14 · May 26, 2021 Sorry for resurrecting this old thread. But I recently purchased a BOSS Audio crossover BX55. It comes with a Bass Knob that has a Q next to the knob and digits 2 (low side) and 20 (max side). I'm thinking this is the Q factor setting. The other knob is labelled Min and Max. I called Boss Audio for some information on this knob as I wasn't sure what exactly it manipulates and if it's an extension of any of the knobs installed on the BX55 unit itself. All the information I got from Boss audio is that the Q knob is the 'Bass Boost' and the Min/max knob is the input level adjustment as in it adjust the input volume from the head unit to the cross over. From experimenting it seems that the remote knob does not correlate or cancel out any of the knobs built in to the BX55. I gathered that the min/max knob indeed adjusts the volume from the headunit to the BX55. But the Q knob seem weird. With the Q knob at the end labelled 2 the bass is loud and boomy, but at 20 it's low and barely heard or felt. Based on what I'm reading on the thread, I'm assuming 2 would narrow the bass frequency down to the Bass boost frequency I set on the cross over, so it should be less boomy, right? 20 on the other end should expand the bass boost to some of the adjacent FQs of what would be set on the crossover. But it's like the opposite is happening, is this actually how the Q factor works or did BOSS audio screw up the knob? maybe it should be labelled 2 to negative 20 (-20). It's just odd, cause i'd think turning the knob right would increase Bass FQs and left would decrease...just as you do with the Min/max knob or....any other knob. And like I said, the controls on the Bass knob does not corelate or cancel out any other knobs so, I can actually continue to crank up the bass boost on the BX55 even though I set the remote Q knob to what I perceive to be max with a lot of bass. Also with the other Min/max knob on the remote set at max, I can further increase Subwoofer output gain on the BX55. So the knob seemingly adds more functionality to the crossover rather than a convenience feature. Attachments
