Best Car Tweeters: Review and Buying Guide (2018 Updates)

Whether you're an audiophile or an auto fiend, getting a great set of car tweeters can make a huge difference in your driving experience. Tweeters come in many styles, shapes, and can offer plenty of variation in sound quality. There are a plethora of features incorporated to modify these products in a range of ways. Combined with all the brands now on the market, it can be a bit overwhelming if you don't know what to look for. Picking out the best car tweeters are easy enough as long you keep just a few things in mind.

What are Car Tweeters and What do they do?

Tweeters specialize in distributing high frequencies - such as guitars, vocals, and horn sounds. These devices usually have a range anywhere from the 2,000 Hz to 20,000 Hz. Because of the significant amount of stress they go under from such high volumes, these devices are typically made from tougher materials. This can be synthetic materials like mylar, Polyamide, or silk, with metal types also being common as well, such as aluminum and titanium.

There are roughly three tweeter designs - cone, semi-dome, and dome shapes. Of these, the cone is the most common but is considered inferior to the other two because of how they disperse sound waves. For increased performance, some higher end tweeters can contain crossovers, magnetic cooling, and waveguides.

Car Tweeter Buying Guide

Without a doubt, sound quality should be your primary focus when picking the best car tweeter. This isn't always a straightforward thing to look at though, as everything from construction material, shape, location, angle, and many more can all affect the sound of your tweeters.

  • Construction Material: While synthetic materials are pretty versatile, textiles like silk do best in mostly plastic vehicle interiors with the windows up. If your vehicle is mostly metal on the inside and is going to be open a lot, you're going to want a metal-based tweeter.
  • Waves Guides: They work by moving the sound waves away from the floorboard and directing them more toward you. They also help keep higher frequencies more evenly distributed across the vehicle.
  • Heat Dispersion: The larger the voice coil, the more efficiently it typically distributes heat coming off of the tweeter. Ferro-fluid can also be part of the magnet to reduce temperatures, which helps the tweeter retain shape
  • Mounting: A tweeter with versatile mounting capabilities can mean you can position it in a spot that sounds the best. Ideally, you want a tweeter higher up and mounted for maximum spread of music. Tweeters are either incorporated into the dash or door, which is called flush mounting, or on top of it, which is a surface mount.
  • Crossovers: These features remove bad frequencies, letting you crank the volume up without getting any of the typical distortions. These crossovers are often passive though, and won't work as well as dedicated crossovers.
  • Cone versus Dome: Aside from the shape itself not distributing the sound as well as dome variants, cone tweeters also typically suffer from being made of cheaper materials - which can cause an additional reduction in sound quality as it becomes more distorted from heat and volume.
  • Large Domes: The larger a dome-shaped tweeter is, typically the better it distributes soundwaves, but it also will require more power. A dome that is too big for your car won’t be able to be powered correctly, messing up the sound quality considerably.

Installation Tips

Best Car Tweeters: Review and Buying Guide (2018 Updates)

While tweeter installation isn't necessarily difficult there are a few things you should consider before you jump on it. Once you figure out your preferred placement it's just a matter of doing the mounting and wiring.

While flush mounting looks better, they do require a cut out to be put in. They also often have angle-mounts built in, allowing you to customize the direction of your tweeter if needed. Surface mounts, on the other hand, require only a screw or two to be held into place.

There are many areas along the door that the tweeter can be added. They are often found on the upper portion of the door, the pillar between the door and the windshield, or even along the sail panel. One of the best areas to put them though is along the dash, as this can push soundwaves through your vehicle the best.

After you’ve picked your spot make sure to cut off power from the battery. This is done by removing the negative (-) terminal from it. By doing this you ensure your electrical components are kept safe from possible shorts. 

If you are doing a flush mount, you’re going to need to remove the panel where your speakers are located and start disconnecting all the old wiring. Speakers and tweeters are typically mounted with screws, so you’re going to need a Phillips screwdriver.

Add any extra things like crossovers, amps, and subwoofers. You’ll probably need some soldering for the wiring, along with making sure all polarities are connected correctly.

Bore out the holes in the panel that you want to mount the tweeters. More mounting brackets might be needed depending on your speaker and car set up

Products used in Conjunction with Tweeters

Best Car Tweeters: Review and Buying Guide (2018 Updates)

Car audio systems can be a complicated and multifaceted process. Tweeters are only a small part of a full audio system and can be used in conjunction with many other devices to improve your music listening experience.

  • Speakers: Factory speakers aren't meant to be the best, just good enough. Getting a new set of speakers are some of the most obvious and cost-effective upgrades you can perform.
  • External Amplifiers: These give additional power to car audio equipment up and above what your car can normally handle. Many setups can’t take advantage of the upper range of wattage found in tweeters and speakers without an amplifier.
  • Dedicated Crossovers: These are a step higher than those built into many tweeters, removing more unsavory frequencies and reducing distortion
  • Insulation: Use a sound deadening product to neutralize vibrations that mess up your speaker and tweeter sound. These materials can also block out noise from the outside, meaning you don’t have to crank your music up as loud, which puts less stress on your system.
  • Equalizer: These devices give you more fine tune control on treble, midrange, and bass frequencies. This can help you get rid of problem areas associated with your audio.
  • Subwoofer: This helps maximize the lows of your music. Since tweeters help with the high, a good subwoofer can bring more balance with boosting up the bottom octave.
  • Capacitors: A machine that works great with wattage heavy systems as they store power and release as needed. Roughly they are buffer between your car battery and amplifier, helping distribute power effectively throughout your audio set up and the rest of your car.

Final Thoughts

While tweeters come in a few different shapes, dome shapes have been shown to be the best in terms of sound dispersion. While metal is often preferred, textile and synthetic materials do have their use. Make sure to pick the right spot, as this can seriously impact the dispersion of the sound waves. When installing remember to put safety first and if you're uncomfortable doing it get a professional. The best tweeters keep shape even under high volume conditions, have built-in crossovers to improve audio quality, and have waveguides to keep the music off the floor.
