How to Accurately test a Re-Cap ?

[nniemiec]

Replaced the caps in my EPI speakers - I used Audyn 10uf caps. How do I know that the tweeters are doing their job proper? after I plug everything back in- I assume I can use a tone generator on my phone connected to my amp & play a tone?

this is all new to me - hoping someone can give me the down & dirty so I know I did it correctly. I did a terrible solder job realizing now i need a real iron vs. the 18v piece of **** that didn't get hot enough. oh well....can always go back and clean that mess up. stupid.

Cheers,

The holes on either side of your head cannot be beat.

As F1nut says, your ears are the best tool. For confirmation, use your treble tone adjustment to verify that the tweeter responds accordingly.

If you are concerned that your soldering job was not up to par, either redo it or use wire nuts. There is nothing wrong with using wire nuts to connect replacement caps in a crossover. My 45 year old KLH speakers have their original wire nuts and they sound great.

Generally, a cold solder joint results in a bad or high resistance connection. Your tweeter output will be greatly reduced or non-existent in that case. But if you can hear sound from your tweeter and your whole speaker sounds good, you can safely assume your soldered connections are good.

Knowing the crossover frequencies is helpful. Use a tone generator. You shouldn't hear low tones through the tweeters nor high tones from the woofers. Most of my recaps resulted in cleaner sound and better imaging.
