dougdrake Posted May 8, 2001 Share Posted May 8, 2001 Can't help you with the break-in period, but the 0/180 switch refers to the phasing of the subwoofer in comparison to your main speakers. As you know, you need to hook both your mains up the same (right to red, left to white, or the other way around -- it doesn't matter, as long as both speakers are hooked up the same). That causes the speakers to be "in phase" with each other, meaning they both "push out" at the same time. Out of phase means one is pushing out while one is retracting (pulling in??). When they are out of phase, they tend to cancel each other out and diminish the sound. With the sub, it can interact with the bass produced by your mains to either enhance or cancel the bass frequencies. Moving the sub's 0/180 switch changes the phasing of the sub in relation to the mains. Set it for whichever setting gives you the best overall bass sound in the room. Good luck!

Ray Garrison Posted May 8, 2001 Share Posted May 8, 2001 just to expand a bit on what dougdrake said... Sound travels at about 1,100 feet per second here in Connecticut. That means that the wavelength of, say, an 80 Hertz signal (think that's about the second D on a bass guitar ) is about 14 feet long. If your subwoofer is 7 feet away from the closest speaker, it is exactly out of phase at that frequency. Playing an 80 Hz signal would result in the sub and the nearest speaker cancelling each other out almost perfectly. (The sub's probably too far away from the other speaker for the phase relationships to matter as much, what with all the reflections from the walls and such.) By flipping the phase switch on the subwoofer from 0 to 180, it would be IN phase with the closer speaker. (At 80 cycles, anyway.) The real situation is much more complex, 'cause music is never just a simple tone at a constant frequency (at least, interesting music tends not to be ). As doug said, try both positions and see which one sounds better. Ray Quote Link to comment Share on other sites More sharing options...
dougdrake Posted May 8, 2001 Share Posted May 8, 2001 Uh, yeah, what Ray said...(to quote RVTaylor). I couldn't have said it better myself. In fact, I couldn't have said it at all. Thanks, Ray!
