snafu Posted May 6, 2012 Report Share Posted May 6, 2012 Um-k . . . the switch you refer to is designed to reverse the phase of the connected subwoofer(s) at the line level. It's two most common uses are: 1. For SQ systems, this allows you to quickly reverse the phase of the subwoofer(s) so that you can get them to integrate better with the front speakers. Keep in mind, in such systems, it is not desirable for the bass to sound as if it is coming from the rear of the vehicle. In some cases, reversing the phase can be the ticket so that the location of the subwoofer(s) becomes less detectable to one's ears. The net result is that the subwoofer(s) will integrate better with the front speakers and the transition from low bass to mid bass is smooth - although each is produced by different drivers in different locations. 2. For high-powered woofer systems with pairs of strapped mono amplifiers, the switch is used to invert the phase of the amplifier used to drive the negative (-) half of the wave form.

SmallTruk Posted May 6, 2012 Report Share Posted May 6, 2012 Some audio bahns have flames on the casing. I've also seen it on Memphis m3s they have Ms on the back. What the hell does that have to do with anything? x2! x3 wtf?? @snafu....ive always wondered why the phase "switch" on some amps was variable like the gain and other controls vs just a ON or OFF, do you know? when it comes to phase the only experience I've even personally had would be to swap speaker wires to accommodate subs that were mounted inverted Quote Link to comment Share on other sites More sharing options...
ALPINE408 Posted May 6, 2012 Report Share Posted May 6, 2012 Snfu is 100% correct best explantion there is For the varible adjustment on the phase has to do with the sq part of what sanfu was saying in order to blend the subs to the front stage a full 180 does not allways work just more tunning options to dial it in more for yur system Quote Have you ever had your woofers blown?

SmallTruk Posted May 6, 2012 Report Share Posted May 6, 2012 Cool. I honestly never knew it was variable, I just assumed it was an alternative to switching wire leads so it was either in or out of phase. Thanks for the lesson guys! Quote Link to comment Share on other sites More sharing options...
Guest Posted May 6, 2012 Report Share Posted May 6, 2012 If your speakers are not mounted inside the box but they are magnet out then the phase 180 allows it to still sound like they are inside the box. lol you're an idiot. inverting subs doesnt have anything to do with phase. they dont "sound" any different if the motor is outside or inside the box. if i remember correctly, the last time you posted had an absurdly wrong answer.

He must have phase confused with polarity.

I thought reversed polarity is what caused a driver to be out of phase? Quote Link to comment Share on other sites More sharing options...
Guest Posted May 6, 2012 Report Share Posted May 6, 2012 (edited) I think he's confused with more than just that... I thought reversed polarity is what caused a driver to be out of phase? it is. if you have a speaker wired in reverse phase and you test it by putting a 9v on the speaker leads, it will suck in. right away a dead indication of reverse phase. all you'd have to do is fix your wiring. usually a + wire hooked where a - should be. correct phase will have the speaker pop out when hooked up to the 9v. you have to reverse the polarity on a sub if you have one mounted normally and the other inverted. just wire the inverted one out of phase.

SmallTruk Posted May 6, 2012 Report Share Posted May 6, 2012 Yah, thats what ive know. So what will the driver do if that phase pot is only partially turned, not at 0 or at 180? Quote Link to comment Share on other sites More sharing options...

In simple terms, polarity refers specifically to the wiring or the motion of the cone. phase is related to the actual sound waves. polarity effects phase but they aren't the same.
