CorNut Posted September 17, 2018 Report Share Posted September 17, 2018 I have some Infinity Kappa 60.9cs 6.5" components, I've had them in my truck for a few years now. Out of curiosity, I took a tester to them and both tweeters say they're reversed polarity. Is that normal? A lot of the Infinity options were 2 ohm, this set was 4 ohm. I'm assuming I didn't wire them both wrong & they're designed to run at 4 ohm by running the components in series? The crossovers are buried in my dash, it'd be a lot of work to make sure they're wired correctly. If it were just 1 of the tweeters, that'd be one thing but since it's both I'm assuming I didn't make a mistake. Is my thinking correct? Link to comment Share on other sites More sharing options...
mothra Posted September 18, 2018 Report Share Posted September 18, 2018 polarity of a tweeter mean minimal. cancellation is likely to not be heard since the cycles per second is so many. if nothing changes, nothing changes You don't know what you don't know, till you don't know Link to comment Share on other sites More sharing options...

The passive crossovers use 2nd order filters. What this means is the polarity of the signal becomes reversed at and around the crossover frequency. This same effect can be countered by reversing the speaker wire polarity of the tweeter when it's a 2-way crossover. The reason to do that is to prevent a dip in the response at the mid-woofer + tweeter crossing frequency. Link to comment Share on other sites More sharing options...

If you are into time alignment, phase is VERY important. And with time alignment, Yes ... There will be a BIG noticeable difference in sound placement. To The Op: change your polarities to the passive crossover, not the tweeter. Depending no how you listen to your music will determine if there will be a noticeable difference. I would always run normal polarity unless a need for a change to set up accurate phase. Hope this helps ...
