reinke Posted December 22, 2008 Report Share Posted December 22, 2008 i want to invert my subs. instead of having the motor inside the bax i want it on the outside. i have always been told that when you do this you have to reverse the polarity. is this true?

audiofanaticz Posted December 22, 2008 Report Share Posted December 22, 2008 No, its not true. You should only have to change the polarity is if your running say 2 subs normal and 1 inverted, or 1 sub normal and 1 inverted. Then you would change the polarity on the inverted sub, or you will have phase issues with 1 sub canceling out the other. Quote Link to comment Share on other sites More sharing options...

Doesn't matter really. As long as all woofers are in phase. Quote BigPimpin91's Banging Music Link to comment Share on other sites More sharing options...
Noobtastic14 Posted December 22, 2008 Report Share Posted December 22, 2008 do both, see which sounds best. you also need to be as in phase as possible with your fronts -Drew Quote I am a United States Military Arts and Crafts Professional.

audiofanaticz Posted December 23, 2008 Report Share Posted December 23, 2008 You also got to remember that inverting your sub(s) will raise internal box volume and will change tuning slightly. Quote Link to comment Share on other sites More sharing options...
reinke Posted December 23, 2008 Author Report Share Posted December 23, 2008 caddy-that would be ok. i built my box a little on the small side so i would not have to rebuild it when i get my new amps. and if i did the math right it would raise my tuning to 41 herts from 38. which is also fine it would help on the mic.

reinke Posted December 23, 2008 Author Report Share Posted December 23, 2008 noobtastic what do you mean by you also need to be as in phase as possible with your fronts. i thought that as long as you wired the speaker/subwoofers carrectly they would all be in phase.

aznboi3644 Posted December 23, 2008 Report Share Posted December 23, 2008 its case dependent. In my truck the sound sounds A LOT better and louder the with sub 180 out of phase with the speakers. With the sub in phase the output drops by atleast 4db I have no idea why though. Quote Link to comment Share on other sites More sharing options...

Infinitely adjustable phase is nice but sometimes just a good old 180 phase switch can work wonders. Generally flipping the phase won't change your burp score on the meter a single bit, but it can have a massive effect on your midbass, as mentioned here. Quote 10.x volts fo' life!
