Inverting subs...

[Nirvalica]

whoever said reverse the + and - is wrong too

you only do that if one sub is inverted and the other is normal

it is still going to be the same wiring

Well then why don't we all just wire our subs in reverse polarity regardless of if it's inverted or not? when you reverse it w/o reversing polarity, you risk canceling out some of the frequencies that may cross with the midbass.

I have not had any problems of this sort with mine the polarity is reversed look at my vids

No, no. What I'm saying is when you invert the sub, you should reverse the polarity. If you don't, it's like reversing the polarity on a sub mounted regularly.

like I said if you have one sub in and one sub out THEN you reverse but otherwise it still the same

but do what you want I was taught wire it the same

If you invert the sub, you reverse the polarity on the speaker terminals. Otherwise the sub will be out of phase. Whether its one sub, 2 subs, isobaric, whatever. Whatever sub is inverted will have its wiring inverted (if you want to look at it that way). Any subs mounted facing normally will have their wiring connected normally.

As said before, the only exception to this would be if you had a 180 degree phase switch.

Anyone who says otherwise doesn't know what they are talking about. I love how misinformation spreads like this.

What would the problem with subs that are out of phase be? (and I mean out of phase with the rest of the system, not subs out of phase with each other). Can you hear a phase difference between a sub and a tweeter or does it only have an effect between bass and mid-bass?

i inverted my sub yesterday w/o reversing polarity and the "kicks" to the song seem missing which i believe are the mid bass frequencies...canceled out i guess but it do sound "heavier".

edit:going to flip it back

Yes you can, its called Time Alignment. Just having the subs mounted and wired normal, there are still time alignment settings that can be done so the sound from the rear speakers and the sound from the frontstage reach the driver at the same time.

If you have a sub inverted and wired normal, the audio signal (sine wave) will be out of phase with the rest of your system.

I couldn't agree more, this thread is full of it.

Very cool, thank your for the answer. I have never messed with anything but normally mounted subs and would have never guessed you can with time alignment and phasing between front stage and subs. Learn something new everyday! I guess this is why some amps have a phase knob that allows you to pick from 0° to 180° rather than only 0° or 180°.
