These bass blocker capacitors block BASS and MID RANGE frequencies to go through the tweeters, and allow your tweeter to handle more power, with louder and more cleaner high frequencies.
You need these capacitor crossovers specially when your tweeters pop, distort or buzz, when you turn up the volume.
Using these capacitor crossovers , in series with the positive terminals of the tweeters, you protect your tweeters from being damage because of bass and mid range frequencies pass through the tweeters.
