Soldering tweeters.. how to do safely?

Uhhhhhh? These?

An externally hosted image should be here but it was not working when we last tested it.

Putting a hot iron to those requires an entirely different process - and if I got into exactly how to do it properly I'll get sinbined until at least 2100.

Hi, just read this thread ands saw comments that silver solder does not have much benefits. I think it is forgotten that silver containing tin/lead solder is mechanically stronger than the version without silver. Sonically I can't hear a difference.

How am I supposed to solder those tweeters then? If you won't tell me how to use them? What good is it?


Hey, kid. Stop bothering that man.

Seems to be the consensus here. Good to know.

LMAO!

You could always use these if you're unsure.

For anyone that wants to do DIY electrical soldering:
Go out and buy two or three diameters of 63/37 solder on 500gm reels.
18g, 22g and 24 or 26g would be a suitable starter kit for most future uses.

Crimps oxidize at the contact points over time. I recently took apart a pair of speakers and cleaned up the contacts with Cramolin. The speakers returned to sounding like they used to. It really improved the sound. I want to use sealing solder as to avoid this oxide built up over time.

Hi everyone!

Anybody know how this cooper foil is soldered to aluminum foil in the picture below in tweeter diaphragm?

 

[vacuphile]

You can solder to aluminum using the right flux.

This one works and is cheap

Solder Flux "FNA" for hard soldering aluminum, steel and nickel parts. 25ml | eBay

 

[AndriyOL]

Thanks. But I think it's done here without a flux because it's covered by paint to avoid oxygen contact

Tweeters are manufactured with standard spade terminals and due to their delicacy I always use spring loaded terminals, no advantage to soldering and the chance of damaging the tweeter is high.

You didn't understand me Javad. I didn't mean how to solder these diaphragm connections to the tweeter, but in what way the cooper part of the diaphragm is soldered to alu part. There are two white dots on the picture which are the coop and alu soldering joints.

That is easy to address with some dielectric grease and some sealing heat shrink if you're really concerned about it.

Andy I wasn't replying to your post specifically, I don't know exactly how that's attached, my guess would be solder and the white material is a sealing or insulating agent.
