[QUOTE="Kip Conner, post: 26689, member: 445"] Re: Crossover Polarity Question To clarify- if you reversed the polarity on the back of the amp you will hear no change (unless you have a FFT built into your brain). At this point you have flipped the HF driver with it. You would notice a change between the monitor and the PA or other wedges on the stage since you have reversed the Polarity (not phase) of the box. If you flipped the polarity of a driver after the passive crossover than you are shifting the response of that driver backward a slight amount (think delayed). It's going to be such a small amount that you wouldn't hear it. You're only going to hear the change in the region where the drivers interact. So if you're passive xover is crossed at 1kHz then you should listen from 800 to 1200 cycles. That range of 400 is somewhat arbitrary because it's based on the slope filters used on the PCB. For instance if a 12dB per octave filter set was used than than the number would be larger than say a 48dB filter since that filter would be tighter. [/QUOTE]
