Caps are used in crossovers as part of a filter circuit with resistors and inductors. Used on tweeters alone as protection from low frequency signals (The cap becomes saturated and keeps current from dumping through the tweet if the signal is to low).
Think of it this way, Caps and inductors act as opposites. Caps eat low frequencies, Inductors/Inductor circuits eat high requencies. By combining the two you can control what frequencies can pass through to each speaker and the amplitude
JBL n28 crossover mod?
i know this is an old thread but I have a pair of JBL N28's that I am planning on using inside an old stereo console and replacing the old hardware with nice 70's pioneer receiver and TT. I am pleased with the sound but was looking to get these speakers to sound better!
Could you share what exactly you did? Maybe a parts list? I am pretty hand with a soldering iron and really eager to learn about modding crossovers. From what I've read, most speakers could use a nice boost with regards to the quality of crossover components. My problem is, I know what the parts look like and generally what they do....but definitely wouldn't know where to start in getting the correct parts or what I would look for to upgrade a current crossover.
Any help with this would be greatly appreciated.
