Marvel Posted December 12, 2019 Share Posted December 12, 2019 Can't... I actually just opened another pound of the stuff last week. I bought it 15 years ago. 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted December 12, 2019 Share Posted December 12, 2019 Maybe I should have sold it... the price has gone up. 1 Quote Link to comment Share on other sites More sharing options...

This list shows the conductive order of some commonly used metals and alloys, based on equal sizes. Pure silver Pure copper Pure gold Aluminum Zinc Nickel Brass Bronze Iron Platinum Steel Lead Stainless steel Isn't most soldering materials a mix of a couple of those? The melting point of some of those would fry the board would it not? Edited December 12, 2019 by STSOE Quote Link to comment Share on other sites More sharing options...
STSOE Posted December 12, 2019 Author Share Posted December 12, 2019 Deang. Just out of curiosity. What did you change on the crossovers you used to make for the Rf's? Did you make it from scratch or did you just alter the stock ones? Just better materials or did you alter the crossover frequency? You haven't made any for the lll have you?

I posted that list just as an FYI on electrically conductive materials, not really soldering elements. And the first four elements are like splitting hairs on conductivity/resistance values. Most of those elements in that list have very high melting points, which would preclude usage in electric soldering. Silver soldering for example requires a torch and temps > 650 C. Elemental silver has a melting point of 962 C. (1763 F) Any of those elements physical properties can be quickly found on wikipedia. Quote Link to comment Share on other sites More sharing options...

Reading from people with actual experience is another. Thanks for the input though. This thread have been quite useful up until now. I learned a lot none the less. 🙂 Quote Link to comment Share on other sites More sharing options...

High pass caps and resistors get changed, and a mod that adjusts a resistor value in the LCR (not applicable to the ii and iii). No change to the crossover point, just a dB drop in output at 3.5kHz which reduces ringing from the cones. I'm really not interested in doing anymore ii's, and won't touch the iii's. I'm tired of the whining and bitching. 1 Quote Link to comment Share on other sites More sharing options...

And have you heard the lll? 1 Quote Link to comment Share on other sites More sharing options...
