i see a few people before talking bout out of phase well what does out of phase mean and how do you know if your speakers are or how can you even tell

i have searched and didnt find much info so i was just wondering those questions

like in a comp set shouldnt the tweet and mid all be hooked up pos to pos and neg to neg right

thanks

180 degree phase is out of phase......it is where one speaker is pushing out when another is pushing in, thus causing cancelation

how do you know if it is or not

and just on a normal comp set in stock loaction the mids are and the tweets are like 4 inches above the mid i have all pos to pos and all neg to neg so how do you know if you are out of phase

typically someone accidentally swaps a + and - on one of the speakers......

A good listener can tell by listening. There are also phase detectors. Just be carefully to mark all pos and neg wires correctly.

It's worth noting that electronic phase does not always corespond with actual phase. Many things affect the actual phase of drivers in a car, including how close to or far from the other drivers they are.

You will sometimes have to wire out of phase to actually get everything in phase. I'd also like to mention that every 12db adjustment in your crossover will flip phase 180 degrees... so by swithching from a 12db slope to a 24db slope may require a reverse in polarity.

Experimention is the key.

You are talking about the difference between perceived, relative and absolute phase. Alot of people confuse their differences.
The term "out of phase", by definition, implies relative phase. (ie: one speaker is out of phase in relation to others)

My terminology may be a little off, but was anything I said untrue?

It was pretty hard to understand, and i already knew what you were trying to say //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

well, all phase is relative.

absolute phase is nothing more then relative phase, where one signal is deemed to be "the reference". eg, it might be "the signal recorded on the CD", or "the input to the amplifier." by selecting a reference to measure phase, phases can be easily compared. This is helpful when you have more than two signals that need to be compared.

to be outta a phase dont u have to have muti amps?? or is that un tru im wondering myself.

my guy is gonna be using 2 kicker 300.1s on 2 crv 12s can this mean there could be a phase issue???

no...you can swap + and - on one speaker and it will be 180 from the other
