Can't find polarity markings on HF driver in Klipsch Forte IV upgrade kit

[Stubb]

I got in a pair of Forte IV upgrade kits, PN #1070334. Installation is going fine, but I can't find polarity markings on the HF drivers. Is there a way to distinguish which one gets the green (+) vs black (-) wire?

 

It's labeled:

 

K-107-TI W/HORN

Any pics?

There's no color dot or marker of any kind near one terminal? Is one terminal wider than the other? I would guess not as you wouldn't be asking. Lol. As mentioned, a pic might help.

if you're looking at the magnet   left to right ,    green wire goes on the  left terminal  ,  black wire goes on the right terminal  ,

Here's a picture of the driver. I'm unclear how you're associating left and right. Turn it so the leads are at 12 o'clock, then green is the left terminal and black the right? Thanks!

 Can you flip it upside down and take a close up of the terminals? Usually there's either a "dot" od paint for positive or a sometimes hard to see "+" indentation.

Thanks for looking! Here's a view from the top. Is the little dot on the left the (+) mark? I didn't notice it until I hit the terminals with a flashlight to make this picture!

I feel a bit better looking at the other driver—I'm not seeing a similar mark on it 😉

Yes, dot positive.

Interesting—on the driver that's marked in my set (link), the dot corresponds to the terminal with the black wire in your picture 🤔

In your picture, I'd say that both terminals are on the right. I'm clearly missing something.

ok  , so here's how we'll do it , take the tweeter magnet facing you , with terminals facing down at 6 O"clock  ,  left terminal  is green , right terminal is black

Has anyone else gotten this kit? Did you have obvious polarity markings on your HF drivers?

 

I ask because one of my drivers appeared to have a polarity mark (white dot), the other one didn't, and that mark contradicts the wiring picture from @OO1.

If this is the same driver, doesn't this pic make it obvious?

Connections are obvious on that pic. It's the mark on one of the drivers that came in my kit (pic below) that makes it a head scratcher.

That doesn't, to me, look like a specific marking. Do they both have the same mark? I would tend to connect the same way as the ones that you took out.

No, only one has a mark like that. The installation instructions say "The tweeter positive terminal will be marked with a (+) symbol, a dot of paint or a colored sticker" so I thought this might be the dot of paint. But odd that only one is marked in this fashion, so maybe it isn't?

I've installed mine the way @OO1 suggested and asked Klipsch support for confirmation. Would be easy if this was a woofer: connect a battery and feel which way the cone moves!

Marvel is correct. Just follow the lead from the one that is marked on the unmarked one.

And finally after all this, if a tweeter sounds out of phase, just reverse the wiring.

[Stubb]

I used a speaker polarity test app on my iPhone and verified that @OO1 is correct on polarity for my drivers. I posted a picture earlier in this thread showing a mark on one of my tweeters—that mark ended up being where the ground wire got connected 😬

 

Trust but verify!

You know this but now that you have this done, get some red finger nail polish from your wife and mark them.  I have learned that some flows too easily (probably because she gives me what she doesn't want) and some puts a nice round dot. 

 

Works great as a breakable thread locker too.
