Speaker Polarity?

Speaker Polarity?

Hello again. I have been doing some fresh calibrating AGAIN and I came across this in all of my searches.......

"Now, play the non-correlated pink noise test signal out of both (front) channels simultaneously, and confirm the level goes up about 3 dB to 86. That's an indication your speakers are in polarity with each other".

This is from the Bob Katz site and when I do this my level still stays at 83db.

So,should I assume that my KrK 5's have a polarity issue or could it be that my room is not treated as good as it should be?

If it is a speaker issue,how would I go about fixing it? I am using 1/4" balanced TRS cables from my mixer to my monitors.

I have a hard time imagining that your monitors are out of polarity, everything you listen to would sound quite odd if they were.

A quick test would be with a kick drum sample (with lots of low end). Make sure both speakers go the same direction, hopefully outward, when the kick hits. If one goes out and the other seems to suck in, then yes, one's out of polarity.

More likely you're doing something funny in your DAW, or the test file isn't correct.

If you discover that one is out of wack, try another set of cables (or switching them, to see if a cable is wired incorrectly.) If you use one cable to test one side, and it's fine, but the other side is 'sucking' then that speaker is possibly wired incorrectly.
