    Crossover question.

    Post  ch46eseaknight on July 3rd 2010, 10:24 pm

    I took the crossovers out of my Paradigms and used a volt meter to measure the resistance . When I measured the upper posts for the highs I got no reading. (by the way, the tweeter has its own board, and the woofers have their own boards) The lower post for the woofers gave me about 4 ohms. So I took the tweeter out and measured direct and got just over 3 ohms. I then measured the wires coming off the crossover to the tweeter and got about the same reading of 3 ohms. I plugged the amp up to the upper posts for the tweeters and they work, but I can not get any resistance or continuity from the posts. I also tried under the posts where they are soldered to the crossover input. The only place I get a resistance or continuity is after the crossover on the wire leads to the tweeters.

    Next I check for continuity on the all the components on the crossovers for the tweeters. The white square blocks i assumed were resistors? They all checked out. Then I checked the cap. I could not get a reading on the cap. I tried the cap for the woofers and it gave me a reading. But not for the tweeter cap. It looks like they used Benin caps. Not sure of the spelling. But should I not get a reading?

    After I was done with one I checked the other speaker, same exact thing. But I did notice a difference on the board. The first crossover I took out has an extra resistor (White Block) soldered to another resistor. Please correct me if i'm wrong but should both crossovers be identical????

    To my knowledge, they should be the same.
