Tweeters are loud speakers that are designed to reproduce high frequencies. In car audio, you will typically find tweeters either mounted coaxially in the middle of mid-range car speakers, or you will find them mounted individually in other locations throughout the vehicle. Component speakers will include a mid-range driver, a tweeter, and in most instances a crossover to filter lower frequencies from the tweeters to prevent damaging them.
Tweeter Styles and Designs
Car Tweeters come in many different sizes, depending on what range of music you are trying to reproduce. A one inch tweeter will usually reproduce notes between 5,000-22,000 Hz, which is the common spectrum of vocals, drum symbols, and guitars. These high frequency drivers come in designs such as Horn, Cone, Bullet, and most commonly Dome tweeters. A dome tweeter will have a very accurate reproduction of music just as the music producer had intended, while horn and bullet tweeters are designed to pierce through large sound pressure levels and be heard over the top of subwoofers and mid-drivers. People using horn tweeters are usually looking for volume out of their car audio system as opposed to a good quality setup.
Why Do You Need Tweeters?
Almost every standard sound system has a set or two of tweeters mounted in the doors, pillars, or coaxially with another speaker. They are very important for maintaining proper imagery and for adding the effect that a band is right in front of you playing each song. Without tweeters music will sound very muffled and bland, as if you were cupping your hands over your ears. If you don’t think you have tweeters in your vehicle currently, there is no need to worry. They can be added fairly easily and aren’t terribly expensive. Different materials that the tweeters are composed of will make your music sound slightly different, and it all depends on your taste. If you aren’t sure what to look for, go to your local car audio shop and listen to some soft material tweeters such as silk, as well as some brighter sounding materials such as aluminum with music you are familiar with.
