Dead Tweeter

[---k---]

Is it possible that my less than amateur soldering skills killed one of my tweeters? I have two new Seas D26NC55 tweeters sitting here. I didn't test either prior to attempting to install them.

The first one is dead. Because the terminals are so small, I attempted to solder some 14ga wire directly to them. I hooked the speaker up, with the crossover and nothing came out from the tweeter. I unhooked the crossover, and attached the leads directly to the wire, no sound. I unsoldered the wires and hooked the leads to the tweeter, no sound. I get absolutely no sound from the tweeter, no static, no hiss, no nothing.

The second one, I put the leads on the tweeter directly, and played some music at very low volume. It sounded fine.

I also soldered the wire directly to the TB W4, and it seems to be okay. So, I can't be all that bad.

So is it more likely that I damaged the tweeter or I got a dead one from Madisound?

Have to tried ohming out the bad tweeter?

I don't even know what that means.

Do you own a volt meter?

On a hunch that means to measure the resistance of the tweeter, the good one measures 4.9. The dead one doesn't give a reading. There is a disconnect somewhere in the tweeter.

It shouldn't measure as an open circuit.

If you have a magnifying glass look to see if you can see the little wire, it's smaller than a human hair. If there's no wire then the tweeter can't play.

On occasion I've been able to repair the tweeter if the wire was just broken and bent off to the side.

Well Ryan, if by any chance you need one I have a single new/unused D26 I'd sell ya.

I really doubt that you damaged it by soldering.

Unless you were soaking the connector in a total excess of heat, but it would take a lot of heat to damage the tweeter like this.

Thanks, I guess my lack of confidence led me to assume that i had damaged them. But, it sounds like I need to give Madisound a call and get a replacement.

Measuring across the terminals should provide some resistance, no? I'm not quite sure what you mean here.

Correct. Open circuit is infinite resistance, meaning no closed path.

[ThomasW]

Yes there should be some resistance. An open circuit = zero ohms.

duh. yeah.

Madisound will send you a new one. No worries.

Ryan,

Check the very fine wire leading from the terminals to the voice coil. It sounds as if you applied too much heat and the wire has come loose. I have done this once. Since then, I've never soldered the internal speaker wiring to a driver and never will again. Quick connects from Madisound are too inexpensive to ruin a tweeter.

This is what I was referring to in my first post

Yeah, I think I see the wire. I can't tell much difference between the two. But, it is barely visible and partially buried in glue. I have no doubt Madisound will take care of it. But, if I was sure it was my fault, I would just buy another one.

Jim,
I agree with you about the disconnects. I have a whole bag of 1/4" ones that I used on the Khans. The Seas and TB driver just use much smaller disconnects, so I didn't have any and figured I would just solder them.

You can get the smaller disconnects from the auto section of Fleet Farm. Nice gold ones too. Not expensive. Though I pushed one on a Seas tweeter once and bent the terminal down 90 degrees cause I wasn't pushing straight down. Just be careful

[---k---]

Farm and Fleet! Hahahaha I live in Chicagoland. The nearest one is about an 45 minutes away. Same with TSC. I've looked before.

I ordered the smaller disconnects this evening along with a replacement tweeter. It was really about just not having them in the house.

Actually an open circuit = infinite ohms. A short = zero ohms.
