What Are Tweeters and What Do Tweeters Do?

The speakers in the car are located near the feet and maybe in the doors and above the boot. Once you switch on the music, the sound fills the space around you. This is all magic of the speakers and tweeters.   

What Are Tweeters?

Speakers are made of different components like voice coils, magnets, cones, etc., that work together to produce the best sounds. Tweeters are small speakers that produce clear treble sounds in-car stereo systems. Woofers create the bass and low-frequency sound, while tweeters are small and are responsible for high-frequency sounds.

These are designed to produce sounds between 2000 to 20,000 Hz and may even be above the frequencies humans can hear. The speakers convert the electric signals into vibrations with the help of magnets and cones. These vibrations are the sound waves that we hear as sound. Tweeters are designed using strong material in different shapes to avoid getting damaged or changing shape with loud volumes. 

What Do Tweeters Do?

The designs of tweeters help us hear the higher frequencies in music known as treble. Tweeters are also essential for the feelings of surrounding sounds instead of keeping them restricted to the direction of the speakers. 

Tweeters receive electrical signals that help the voice coil create a magnetic field area. The magnetic coil leads the back and forth movement of the coil and domes in the tweeters leading to sound waves. The signals may be different, and the vibrations catch the smallest differences too. 

When the system stops, the tweeters can control the vibrations immediately, and this process is called Damping, which is significant for a good system. Tweeters combine with the other speakers and add quality and sound effects. Large speakers and woofers can only produce low frequencies. Hence a good system needs both the woofers and tweeters to get a clear sound and wider frequency range.  

Tweeters Are Important

The intricate sounds are not audible without tweeters, and the full range of speakers with woofers and tweeters must exist together. Even in a car stereo, you may hear the high-frequency sounds, but they will not be as good as the ones from tweeters. The usual speakers direct the sounds in one direction, while tweeters help them disperse equally within the space, enhancing the listeners’ experience. 

Tweeters can also create an image with the help of audio frequencies. They can reproduce a stereo image of the recording of different instruments and help the listener with the same placement. This is significant as the tweeters translate the music for the listeners the way the creators wanted them to hear with complete direction and frequency range perspectives. 

What May You Need For Tweeters?

Speaker crossovers direct the sound frequencies to woofers or tweeters. Without crossovers, if tweeters receive a wrong signal or low-frequency sounds, the output will be distorted. In fact, in the absence of crossovers, the tweeters may be destroyed if too many low-frequency signals reach them, and therefore you must have speaker crossovers for the system in place. 

Location of Tweeters in your car

Tweeters are added to the speaker system with a woofer, crossovers, and a tweeter. Tweeters must be in a position near the shoulder level, in the front part of the car, and fitted apart from the other tweeters. You can use an enclosure to keep the components of tweeters and woofers safe.

The surface mount method uses tweeters on the top of the speaker. It can use a flush mount to install the tweeter inside the surface. It can be mounted against an existing grill in the bottom mount. The surface mount method can be used to palace tweeter between the windshield and front window on the ‘A-pillar. 

If the system does not have a tweeter already, you can install a tweeter using a flush mount in the upper area of the car door. Factory-installed tweeters may use a bottom mount system. But you can use the sail panel in the door window to install the tweeters too. A preinstalled tweeter may be in the dash, so you can use the bottom mount method or create a bracket for your new tweeter. 

Tweeter Impedance

The load a speaker puts on the amp is measured in Ohms as its resistance. The tweeter’s Impedance changes with the frequency and is the system’s impedance. Crossovers are designed according to these factors of impedance and resistance, and hence their proper calibration is crucial. 

Tweeter Power 

The power of the tweeter and speakers is essential as they must match and not damage the amplifiers by overheating. Most tweeters are small and cannot handle the power like the large speakers as they disperse the watts due to the large surface area. In addition, tweeters have smaller voice coils and cannot offer much resistance to power. 

Different Types of Tweeters

● Cone tweeters are very common, made of light material, and are inexpensive. They may not do a great job of enhancing the sound quality. 

● A dome-shaped tweeter helps disperse the sound to a wider space. The high-frequency sounds travel in one direction. The dome shape helps them by providing a larger area. 

● Super Tweeters can produce higher volumes, are used in louder speakers, and usually have higher power ratings. But the sound quality may not be that great. 

● Ribbon tweeters are unique, and their function is also different. The ribbon moves due to a magnetic force instead of a diaphragm and produces better sound quality.

● The piezoelectric crystal vibrates due to the electric current, leading to the diaphragm’s vibration and producing sounds.

● Plasma tweeters have a sphere of plasma that produces sounds when electrically charged. They are very sensitive to signals and are usually paired with horns to improve sound quality.

● Electrostatic tweeters have a diaphragm between two metal screens, creating vibrations due to electric signals. 

● Any of these tweeters may have a horned structure attached which controls the dispersion of sound with efficiency and better sound quality. 

● Concentric tweeters have rings and center plugs, and the entire system moves. They may not provide good dispersion and must face the listener directly. 

Conclusion

Tweeters are small speakers that produce high-frequency sounds that the woofers and speakers cannot produce. Tweeters work along with the other system components to improve the sound quality and the best details.
