Are your 1.2TL's tweeters wired wrong by factory like mine?

But I'm lazy and would rather just terminate the colored wires with a wide blade and be done with it....

Then the tweeters will not work properly.

michaeljhsda2

but then again if i switch the wires in the harness I could spray them with deoxit and freshen them up a bit.

Are you sure Jerry's xover is upgraded to TL. If it is, the largest capacitor would be 27uf. The one standing vertically on the board corner. If a 1.2 model xover, the largest capacitor is 40uf, probably mounted same way.

I'll change the wires over. Thanks a million for your help Rich.

Yes TL upgrade. Ben from the forum did it this year.

Before you change the pin wiring configuration, you should check with Ben. I would think Ben wired the xover exactly as in the 1.2TL schematic, so most likely you have to change the wires on connector. If you do not change wires, tweeters will work but not as designed to.

Will do thanks. Tomorrow (today) i'm gonna take the left channel crossover out of Jerry's 1.2's and see how the colored wires are in the harness...should be the same as the right channel with the colored wires on the positive harness (i'm talking about jerry's 1.2's soon to be 1.2 TL's but it seems l recall that the wires on the left channel were like your's and mine...white on positive position of the harness. Jerry's speakers had all kinds of crazy issues like the label on the back of the cabinet showing blade/blade although his speakers has a PIN/BLADE!!!!...check out the thread if your interested. http://www.polkaudio.com/forums/showthread.php?t=87728

goodnight all

JHC, ya'll are making my head spin.

"OK" I pulled my crossover plates to look at my tweeter connections. all do to this thread. Just to double check.

My 1.2's where modded by Ben as well to 1.2tl's.

The blue,green,red,and yellow wires are on the + side,and white wires to the - and connected to the wide terminal on the tweeters.

And looking at the schematic's mine are correct..

Are you looking at the 1.2 schematic or the 1.2 TL schematic? According to Rich, now that you have the 1.2 TL crossover upgrade you should go by the 1.2 TL schematic whereby the white wires should be on the positives on the wire harness/xover board and then each white wire would go to the the negative (wide post) on each tweeter. This would require a special tool to switch out the colored and white wires on the wire harness plug.

Here is a photo my 1.2 TL harness. This is not Jerry's 1.2 harness.

I am looking right at the schematic's for the 1.2tl's and it shows the white wires on the - neg's


You can veiw it here just scroll down to 1.2tl

That looks backwards to me. mine is B+ W- G+ W- R+ W- Y+ W-


I am sure it is all the same as long as each wire is going to the right place.

Correct. And so is Jerry's 1.2 wire harness. It's just like yours. However, I own a pair of 1.2 TL's (original, never upgraded from 1.2's to 1.2 TL's) and my wire harness is the opposite of Jerry's and yours.

michaeljhsda2

Rich talked about the "trace" of the board and I believe he's talking about the underneath side of the xover board that shows the lead traces. The 1.2 board "trace" is different that the 1.2 TL board "trace"....

Toolfan66

Looking at the schematic's for the 1.2 and 1.2tl the 1.2's would be wired like yours, Whites on the positive. and the tl's would be wired like mine whites on the neg's

If I am wrong someone chime in..

michaeljhsda2

Have you looked at the schematic for the 1.2 xover board? I realize you board has been upgraded to the TL but the "trace" is still there on your 1.2 xover board...the "trace" can't get physically changed but other things are done to the 1.2 board that would make it a 1.2 TL.. sorry I don't know the exact nature of what is involved in doing that but I read that's what is done.

Toolfan66

They are the same board just wired differently.

I don't know eather but I am sure Ben F1nut or Face would know.

If my speakers, the original unmodified TL's, are correct then the wiring is as follows. The white wires are in the positive position on the harness but they go up to the negative post on each tweeter.

I see what you are seeing now on the schematic's. so if this is true then do the tl upgrade on the 1.2's need to be wired the same way?

I'm not so sure about that because Rich stated that the "trace" was different on the 1.2 board compared to the 1.2 TL board. Give me a minute and I'll go back up in the thread and reread what he said about the difference between the 2.

michaeljhsda2

Just thinking out loud Larry but now that your crossover has been modified to the TL, whereby the trace differences have now been resolved by changing values on the board, that now it's just a matter of changing the wire harness to look like my original 1.2 TL harness? The photo in post #74. White on positive on the board and trace up to negative (wide blade) post of the tweeter.

I believe so. See above post.

Yes, I see that. Do you see that the color code for T1-T4tweeter wires is incorrect on the schematic? Look at the circuit. You will see that T1-T4 (+) wires all tie together. The color code shown would tie the (-) together which is correct for the 1.2, but wrong for the TL. Look at yours with the tweeters plugged into the xover. Are the White wires on a pin that is marked (+) on the board? If "yes" then yours are wired correctly and you have TL's to begin with. If you have 1.2's with xover upgraded to TL's, the White wires connect to the (-) pins and have to be changed to match the TL schematic. (If you upgraded, ignore the 1.2 schamatic and use only the TL schematic.)

You could also compare your wiring harness to the TL schematic circuitry in case harnesses and color codes are different. Ignore the color code on the schematic. All the wires from the (+) speaker terminal should connect to a pin marked (-) on the xover board. The (-) speaker terminalwires should connect to a pin marked (+) on the xover board. Post #74 shows a photo of this and shows the correct 1.2TL tweeter wire connections to the pins.

I did not state the trace on the TL and 1.2 are different. I stated I did not know. I would assume both are the same though. (The trace connects all the tweeter pins marked (-) together.) The board was made to be used for differntly designed circuits. Because I do not know if boards are the same or not for different models, I said look at the trace. For Tl's the trace should connect all tweeter (+) wires together no matter what phase is marked on the board. For 1.2's the (-) tie together.

Toolfan66

So what your saying is my upgraded 1.2's to tl's is wired wrong? if this is the case would it not just make sense to swap the terminals at the tweeters and be done?

And another question if wired wrong why do they sound so good?

If DK or Face, F1nut and or Ben could give us that second opinon.

No disrespect to you Rich as it sounds and looks like you are correct in your findings looking at the schamatics my self, But I would like to here from some of the other guys on this issue.

This is incorrect. It is backward. You are only looking at the color code at the pins on the schematic. These colors are wrong if you look at the circuit. For 1.2's the whites should connect to pins marked (-) at the crossover. On TL's the whites connect to pins marked (+) at the xover. And once again, the whites must connect to the proper (-) pin for correct tweeter "firing order." You have to follow the circuit to determine this.

For TL's your wires should be inserted into the connector in the color order shown in post #74 photo.
