[QUOTE="squeak9798, post: 2203708, member: 555320"] It's there for general use. There is no one specific scenario. Atleast, I wouldn't think it would be there for any one specific scenario. I guess I'm not the designer, so I can't say for 100% certainty what went throught their or IA's mind on why to include it. But, you can use it for general purposes and it does not need to be used in any one particular scenario. In some installations, reversing the phase of the subwoofer will acheive the best performance (blending best with your setup, etc). In which case, it's simply easier to flip a switch/turn a knob to do so as opposed to swapping wires. Also, to clarify....it doesn't really make the sub move "backwards"...it reverses the peaks and valleys in the signal, thus "reversing" when the sub excurts outward and inward in relation to the original signal on the CD and also the other speakers in the car.
