Everybody wants their "highs" a certain way. Sound quality systems demand clear highs with an "airy" quality. Some people want sizzling highs (you won't find any bugs in their cars). BOSS makes tweeters to handle the high frequency requirements of any system, including smooth-sounding silk soft domes, micro dome tweeters for easy system add-on, killer bullet tweeters, and even chrome tweeters, for a touch of metal.
