  • Simple tweeter solder technique

    For those that solder leads to the tweeter terminals, I started doing this simple system a while ago and thought I might share.

    1) Fold the leads through the hole in the tweeter terminal loosely.
    2) Pull them back and tape with painters tape to the back of the tweeter.
    3) Optionally compress the wire onto the terminal a bit with needle nose pliers.
    4) Solder.

    Like so:

    It has worked well for me, and just makes life really easy.

    Placing an alligator or crocodile clip on the terminal between the wire and the terminal mount will act like a heatsink and not overheat and possibly desolder the tinsel leads to the diaphragm.

      Excellent point, I forgot to mention that. I haven't used that trick myself, but I keep the solder time short. Once the solder melts I count to 8 or so. I have heard horror stories of destroyed tweeter tinsel leads by soldering.

        Or a bit of wet paper towel. I count to one.

          What temp's do you guys solder at?

            Somewhere I read at one point 500 to 550 is good for most common solder so I tend to stick with that. I am actually not sure how accurate that is, since I can't recall where I read it.

              The avionic techs I know all say 700 degrees.

                I'll need to post pictures of my technique - but here's a quick decription:

                1 - I use an old solder iron that gets hot enough to melt plastic, but not solder
                2 - Push the solder iron hard against the terminal, in an attempt to get enough heat transfer to melt solder
                3 - Notice plastic frame has melted
                4 - Burn fingers holding terminal in place until plastic cools (needle nose pliers should always just out of reach).
                5 - Pray voice coil lead hasn't de-soldered itself from the terminal.
                6 - Get decent soldering iron and try again.

                    At about 1,000,000 degrees Fahrenheit. Well not really, but I like a good hot iron that allows me to get it done quickly. I hate having to heat the whole thing up, potentially risking the melting of plastic or something.

                        That's hilarious!!! ...and yet true.

                        Of course heat depends on solder type. The Silver stuff needs more heat. Standard 60/40, I use enough heat to do the job without it being slow. Generally, this equates to about 480* for 60/40, and closer to 500 for the Silver- or more.

                        Oh yeah- I use a BlackJack Solderworx RoHS compliant unit. I really like it!

                          Also use an old roll of tape to set the tweeter on so as not to damage the cone. I also like to tape the leads to the tweeter magnet when done to add a little more support.
                          If we all reacted the same way, we'd be predictable, and there's always more than one way to view a situation.
                          What's true for the group is also true for the individual. It's simple: Overspecialize, and you breed in weakness.
                          It's slow death.

                            After a first-time effort with the tabs getting too hot and releasing themselves from their mounts, I started using Wolf's suggestion of a small alligator clip below the little wire hole on the terminal. Some of those small Audax and Tang Band tweeter terminals at .110 size were a bit tedious, but a small alligator clip did work quite well. I've taken to using that method when soldering to capacitors also. Although I don't use more heat than necessary, a little extra step with the clip has kept me from loosing the tabs and/or tinsel leads ever since. Taping the wire in place is also a great tip.

                              Good stuff Chad

                              This is a timely thread after I recently destroyed two DTA-2 amps due to my soldering butchery. 3rd time's the charm tho!
