What Exactly Is a Tweeter Speaker?

Tweeters are an integral part of most speaker system setups. They either sit separately in multi-speaker arrangements or as part of single-unit systems. But what is a tweeter?

A tweeter speaker is a type of speaker designed to produce sound in the higher frequency range. They’re important accompaniments for woofers and other speakers unable to reproduce higher-pitched sound frequencies. The best sound setups include tweeters to ensure the perfect listening experience.

In the rest of the article, I’ll explain more about tweeter speakers, what they do, and the different types available. I’ll also provide you with some of the best options available today that you can get for your setup.

Tweeter Speaker Design

Tweeters have a compact design because they produce smaller sound waves. The small cone also means they’re designed to point directly to the listener. Their sound range is mostly within 3-20 kilohertz, but some manufacturers can implement different limitations.

The standard design of a tweeter consists of the following:

  • A small magnet with a circular gap on the inside.
  • A copper wire voice coil connected to the speaker dome.

The speaker assembly is affixed into the gap within the magnet. The dome is held together on its side by some tough but flexible material.

Amplified music signal reaches the tweeter via the standard positive(+)/negative(-) wiring connections. Once this happens, the voice coil triggers a magnetic field within the magnetic gap region. 

The reaction causes the tweeter coil and dome to move back and forth, cycling air quickly to trail the signal. A combination of these intricate movements leads to sounds you hear.

The Role of Tweeter Speakers

As mentioned earlier, tweeter speakers produce trebles and other high-frequency sounds such as synthetic keyboard sounds, cymbals, drum hi-hats, etc. 

They complement other speakers that aren’t designed to replicate such sound. Combined with a subwoofer and standard 2-way speakers, tweeters can help ensure near-perfect sound reproduction.

Tweeters are important in music because they ensure listeners hear the full range of sounds in any piece of music or movie. Sound setups, including tweeters, sound more pleasing and more natural compared to those without them.

Tweeter Impedance and Power Ratings Explained

Impedance describes a speaker’s total electrical resistance to current. The unit is in Ohms. The voice coil in any tweeter speaker features a long amount of wire wound into a coil. The wire has electrical resistance. 

Impedance rating is important because you need to know what it is to choose the right matching components for your tweeter (or the other way round).

Mismatched speaker impedance causes one to play at volumes far higher than the other. 

Generally, home tweeters are rated at 8 ohms, while car options are rated at 4 ohms. However, those numbers are generally an estimate. A tweeter speaker with an 8 ohms rating is most likely a 6-7 ohms speaker. Keep this in mind when it’s time to choose your tweeter speaker.

Your tweeters have to match the rated impedance expected from an amplifier. Amplifiers can overheat if used with speakers too low for the design. So, for example, you can’t use a 4 ohms tweeter if the amplifier has an 8 ohms rating.

On power ratings, the first thing you should know is that tweeter speakers aren’t designed to handle the same level of power as other large speakers. Woofers and subwoofers can deal with larger amounts of heat because they all feature a larger voice coil wiring gauge. 

You should expect around 15W RMS for most home tweeter speakers. However, it’s not uncommon to find models with up to 50W of power rating at the higher end of the price scale. 

Different Types of Tweeters and Dome Materials 

Tweeter speakers come with domes made of a wide range of materials. Some of the common options you can expect to find include:

  • Kapton
  • Ceramics or ceramic-coated domes
  • Metal (alloys, titanium, and aluminum)
  • Metal-coated plastics
  • Mylar
  • Textile (silk and other materials)

You may occasionally come across some less common materials, but always be sure to get clarity on the type of material used in making the tweeter. Some obscure brands aren’t always clear in this regard.

Textile or silk are the most common tweeter speaker materials you can find. For models in the middle or upper range bracket, you may occasionally find aluminum or titanium as the material. 

Let’s look at tweeters made of these materials in a bit more detail.

Mylar or PEI Tweeters

The dome in Mylar and PEI tweeters is made of plastics. You’ll find these in budget or coaxial sound setups. They’re the affordable option to go with, but they’re not the best if you’re looking for the most accurate sound replication. You can easily notice the difference when comparing the sound to what you’ll hear on a silk dome tweeter. 

Some of these models use a type of metal coating to create a hybrid solution that may or may not improve the overall sound quality.

Silk Tweeters

Silk tweeters are popular for their extra stiffness and a specific tinge of sound. Some silk tweeters combine materials like diamond or ceramic to increase sound quality even further. 

However, it’s important to note that the material used in making your tweeter dome isn’t the sole factor that determines quality. Look at the relevant frequency charts for a more reliable take on the quality of the product.

Where the frequency chart is not available, you should request more information or go with a model that supplies the chart. Failing to do so, you may end up with a tweeter that will deliver extremely harsh sounds or one that emphasizes specific sound ranges too much or too little.

Bullet and Super Tweeters

Bullet and super tweeters are similar to others we’ve mentioned here, but they may have a bullet shape in the dome to accentuate the sounds produced. These designs are good options because they deliver some of the highest volumes and ensure excellent power handling. 

They’re great for scenarios where high power handling and loud volumes are necessary. So, you should probably look elsewhere if you’re in the market for a tweeter speaker to use indoors.

Compression Horn and Horn Tweeters

These are a special class of speakers. Entry-level models in this range are also affordable, but they’re not the greatest in producing good musical tones. They also have slightly higher volumes compared to tweeters of a similar size.

The important distinguishing factor between these tweeters and others is that they feature piezoelectric crystals instead of a magnet, as with other models. The piezoelectric crystal is connected to a mechanical diaphragm such as a digital or electronic clock. These designs often have high impedance.

Concentric/Ring Radiator Tweeters

Concentric radiators are a rare group. They feature a combination of moving surfaces made of a center plug and several rings. These tweeters are more sonically accurate, delivering more musical detail overall. 

A major downside of these tweeters is that they don’t sound great in arrangements where they aren’t directly facing the listener.

Ribbon Tweeters

Ribbon tweeters are slightly different from the rest. Their design features a thin ribbon diaphragm that produces sound by moving back and forth in a linear model. They’re some of the most common in the market today, and they deliver some of the best sounds. 

However, the level of quality will vary across price ranges. The $600 models will sound better than the $50 models.

One of the main reasons for their quality is that their impedance is flatter on the frequency response range compared to tweeters featuring a magnet and a voice coil.

Factors To Consider When Choosing a Tweeter Speaker

To help you choose the perfect tweeter speaker, here are some factors you should keep in mind:

Build Quality and Construction

You need to pay attention to the build, shape, and design of your tweeter speakers. As we’ve seen above, tweeters can be made of a wide range of materials, including ceramic, Mylar, alloy, aluminum, textile, and more. 

Choose the option that best fits the use case. You’ll get the most durability from the speakers with the metallic build, but the Mylar or plastic products can also work well.

Power Rating

You need to choose a tweeter speaker with the right impedance and RMS power rating to fit your wider sound system. It’s important to avoid mismatching your amplifier impedances and your speaker. Such a setup will leave you with uneven or tainted audio delivery. 

It’s also a good idea to confirm the efficiency rating of the tweeter—a measure of the level of sound your speakers can produce with a specific amount of power. You should watch for an efficiency rating of 91 decibels per watt.

Speaker Sensitivity

The sensitivity of your tweeter should be at least 90 decibels. Higher sensitivity ratings ensure louder top-end sounds overall. 

However, the sensitivity should match the rest of your speaker system if you’re to enjoy the best results. Most of our recommended tweeters have a sensitivity rating of 95+ decibels.

Speaker Cost 

How high are you willing to go? You should compare the cost of speakers you’re considering to your budget. 

Affordable tweeter speakers can still improve your sound system, but the key is to find a tweeter speaker within the price category of the sound setup you intend to use it with. Using a $100 tweeter with a $2000 speaker system won’t change the sound results.

Final Thoughts

Tweeter speakers are important fixtures in any audiovisual setup. They work to enhance the sound clarity and ensure you can pick up more distinct treble sounds. When combined with the right woofers and subwoofers, tweeters can instantly improve your overall listening experience.

Just be sure to always go for tweeters that match your existing sound setup in impedance and power rating. It’s a guaranteed way to avoid corrupted sound and potential damage to all or some of your sound equipment.
