When building or upgrading your car audio system, a great woofer and speaker is not enough, you need to include tweeters to truly appreciate those sweet high notes.

This is because audio is broken into different frequency ranges, and to fully enjoy them, you need different speakers: woofers for the low frequencies, speakers for mid-range frequencies, and tweeters for the higher frequencies.

But installing the wrong set of tweeters can significantly alter sound quality. So how can you make the right choice?

Depends on your system and sound preferences. Tweeters are made from different materials and shapes, and they deliver various power, and range, which means that not all tweeters will work for every audio system.

These high-efficiency tweeters make the top the list because of the sound it delivers, efficiency and power handling all at a great price.

The TS-B350 Pro has materials and performance above other tweeters in is class. They are built with a titanium diaphragm and aluminum chassis and feature aggressive magnets and motor assemblies that produce a wide range of frequencies up to 250 watts RMS.

Pioneer delivers a record-breaking sensitivity of 100 dB, 4- ohm impedance and a wide frequency response that goes up to 27000 Hz. They are designed for users that enjoy big tweeters with exceptional loudness.

Of all the tweeters reviewed these Pioneer tweeters deliver the best value considering power handling and efficiency. They are also flexible, even though they work best with high-power systems thanks to their outstanding sensitivity they are also suitable for low powered systems.

This set of two JBL tweeters are a popular pick.

JBL GTO19T Premium 0.75-Inch Component Tweeter are versatile and can be added to almost any system.

JBL GTO19T Premium have a soft dome design, can handle up to 135 watts of peak power, and have a 3-ohm impedance.

They are easy to install, have a fixed mounting and a carbon-magnetic basket that maintains precision under demanding conditions.

These tweeters produce smooth and crisp high notes and generate heat dissipation and higher handling thanks to its soft dome and oversized coils that drive higher power and enhance heat dissipation that prevents heat build-up and the speaker's performance.

They are also machined to high precision so you do not have to worry about reverberation during high volumes.

These Alpine tweeters, that are also included with Alpine’s Type S Component Speakers, are available as a separate component to enhance any audio system.

The 1-inch silk dome pair of tweeters are designed for high-frequency range and high efficiency.

With a sensitivity of 88 dB, an impedance of 4-ohms, a frequency response of up to 21KHZ, and a 300 watts peak power, these pair of tweeters will deliver great crisp sound that can be heard at high volume without distortion.

The size of the tweeters, stealth OEM mount, and a ¾ deep flush mount result in easy installation, and you can fit them almost anywhere!

Rockford Fosgate’s delivers its traditional quality and sound with these 1 in tweeters that feature a ½ in lightweight mylar dome tweeters for high sensitivity and smooth and extended frequency response.

With a power handling peak of 160 watts per set (80 watts on each side) these tweeters will deliver loud and clear sound.

The R1T-S has a frequency response of 2500-22000z and 80W RMS, 4-ohm nominal impedance, and their built-in passive crossovers ( 6dB/octave HP) result in higher quality, distortion-free audio.

These tweeters are easy to install they have multiple mounting options and come with a flush, angle, and surface mount hardware, so you can virtually install them anywhere.

These aluminum super bullet tweeters will deliver powerful and fuller sound at any volume for an amazing price.

The PRO-TW120 are made of aluminum for power and durability.

They feature 200 watts RMS and 300 watts max power and a built-in capacity filter.

They have a nominal impedance of 4 -ohms, provides powerful and clear sound with a frequency response of 2Khz- 20Khz and a sensitivity of 103 dB that results in clear and deep sound.

Thanks to its high-quality materials these tweeters produce loud and full sound even though they do not have the highest frequency range.

First things first, the Polk Audio DB1001 is neither the most stylish tweeter nor the one with the widest frequency response.

This is a slight issue considering that it’s built specifically to be flush-mounted or surface-mounted. However, so long as you’re okay with making those compromises, these tweeters aren’t half-bad.

Marine-certified and made with silk-polymer composite domes, the DB1001 boasts a peak power rating of 180 watts with a 60-watt RMS.

These aren’t the most impressive numbers, but they’re above average. But they’re not the main selling point of the DB1001. Instead, its the passive 12db/octave crossover that it comes with, giving the tweeter excellent performance and durability. Not to mention, it’s backed by a 1-year warranty by the folks over at Polk Audio, which adds a bit of peace of mind. 

If you’re looking for a pair of tweeters that offer the same clarity of aluminum tweeters without the bright and colorful tones commonly associated with them, then the Kicker 43CST204 is definitely worth a look.

These titanium dome-shaped tweeters measure merely a quarter-inch in terms of diameter, but it packs quite a wallop with a 100-watt peak power capacity. As a result, it will have no trouble keeping up with an enthusiast-grade car audio system. Also, because of its high power handling capabilities, higher frequencies will be no trouble to the 43CST204.

Another reason why it’s worth pointing out the titanium construction of the Kicker 43CST204 is its ideal mix of lightweight and strength. Despite being light in weight, the material is stiff enough to minimize if not completely eliminate rattling at higher volumes.

The Kicker 43CST204 is also capable of performing at its best without an amplifier because of its 92-decibel sensitivity rating.

Money, or specifically the lack thereof, is not and shouldn’t be an issue to upgrading your car’s stereo system, as the Power Acoustik NB-2 will prove to you.

One of the most affordable tweeters on our round-up, these tweeters come with a peak power rating of 200 watts and an RMS of 100 watts. This means that it’s quite powerful.

But while the music reproduction capability leaves a lot of room for improvement, they’re not half-bad, especially if you’re not an audiophile.

Also, remember, you’re making a minimal investment here, and in return, you’re getting a lot.

Quality nor power isn’t the main selling point of the Power Acoustik NB-2 either. Rather, it is its 3-way mounting capability that allows you to install it in many ways. However, we do recommend installing a resistor for, you know, to prevent the tweeters from blowing up in case you play the music too loudly.
