Brand JBL
Peak Power 600 watts per pair
RMS Power 300 watts each
Frequency response 45-21,000 Hz
Sensitivity 94 dB
Dimensions ‎‎10 x 9 x 10 inches

The JBL GTO939 speakers have Plus One cone technology that uses specialist materials to make a cone bigger than average. A JBL GTO939 speaker produces sound by vibrating air, so a large cone vibrates more air for a better bass quality.

Each JBL GTO939 speaker handles 300 watts or 600 watts for a pair. Both speakers have RMS power handling of 100 watts and 200 watts.

These JBL GTO939 speakers have a 94dB (decibel) sensitivity rating, so you use around 50 watts of power after setting the volume. You need about 100 watts for the exact volume level when using 91dB speakers.

Tweeters in the JBL GTO939 allow the unit to compete with others in the higher price bracket. Each one-inch tweeter is a titanium and Mylar composite (My/Ti), which helps reduce distortion, increase power handling, and increase efficiency.

These JBL GTO939 speakers also have a UniPivot JBL system for adjusting the tweeter position. An included control switch offers installation customization to improve dB output to your preferences.

The Buyer’s Guide to Choosing the Best 6×9 Speaker for Bass

We’ve seen the best of the best—these are the top 6×9 speakers on the market for taking your soundscape from ordinary to the next level.

However, the selection process is more challenging than you might imagine.

When it comes to the best speakers for your car, you want a harmonious music experience, you also don’t want to invest in a pair that burns a hole in your wallet. What you want is an economical buy offering well-balanced and clear audio.

But the sea of options on the market makes choosing the best units for your ride harder. And you can’t go testing the sound quality of all the models. But we did!

The result is this guide to the best 6×9 speakers.

What Are 6×9 Speakers?

These speakers feature an oval shape measuring 9 inches wide and 6 inches high. The 6×9 is the woofer cone’s measurement. They offer a small upgrade in size, power, and volume compared to our favorite 6×8 car audio speakers.

The shape makes it possible for the speaker to pack a real punch – they’ll move much more air and be considerably louder than even elite 5.25 speakers. Additions in a speaker improve the overall audio quality compared to traditional circular sound systems.

These 6×9 speaker models are the most reliable replacements for factory-installed vehicle speakers. You require little space and receive excellent sound quality with a few tweaks and amplification.

Some drivers prefer pairing their 6×9 speakers with an additional subwoofer to get the minimum bass frequency.

Benefits of Installing 6×9 Speakers

Choosing and installing car speakers is difficult. You need to account for various factors, including amplification, subwoofers, tweeters, crossovers, and capacitors.

Make the process easier by investing in a pair of the best 6×9 speakers. They will provide high-quality sound with all features combined.

The 6×9 speakers also offer excellent performance across all sound spectrum frequencies. So you’ll experience a punchy, deep bass all thanks to the size and shape of the speaker woofer.

An impressive benefit of 6×9 speakers is that they generate the perfect mid-range sounds. They can also achieve high frequencies because of integrated tweeters.

Great vehicle speakers should come with a few features you need to learn about. We now embark on finding out the factors to consider when buying.

Type of 6×9 Speakers

These are the basic types of speakers on the market:


They offer decent bass and good mid-range frequencies but may not fulfill the higher frequency range. A single 6×9 speaker is a good option for pairing with a factory speaker system and filling it out. It’s also a good choice if you want to replace the larger speakers on the back deck of a car for a fuller, premium sound.


Consider these speakers as two-in-ones. The 6×9 speaker cone comprises a smaller one or two-inch tweeter.

Two-way models are suitable for filling out in the higher mid-range and for producing piercing high-quality frequency capabilities. The speakers are also suitable for coherent sound without overtaxing the 6×9 cone capabilities of producing high notes.

The two-way is an excellent option if you’re looking for a stand-alone speaker with good sound quality.


Three-way 6×9 speakers are the most versatile and best-sounding units. Each unit comes with two different tweeters and the 6×9 to handle ultra-high and high-mid frequency sounds.

These speakers fill out quality music a lot more and offer strong capabilities. The three-way models are an excellent option for the stand-alone unit. The sound stays at its best whether you’re playing a symphony or a rock tune since the three different speakers share the load.

Coaxial Speakers

Also known as full-range speakers, coaxial 6×9 speakers help you save money and space. These models combine multiple drivers into a single speaker and are easy to install.

Component Speakers

These speakers break down the sound system into multiple sets, including mid-range speakers, subwoofers, and tweeters. Separating the items allows easy customization of your sound. Even smaller 6.5 component speakers offer excellent sound quality thanks to the split components.

Always consider the crossover when buying component speakers. You’ll need an external crossover, so the right frequency goes to the correct audio component. Coaxial speakers have built-in crossover functionality.

Frequency Response

Frequency is the measure of pitch and range of highs and lows coming from tweeters, woofers, and more. The frequency response is how wide the frequencies a 6×9 speaker reproduces.

Avoid speaker systems with a poor frequency balance. Systems with too much emphasis on low frequencies may distort the higher frequency sounds. Choose a 6×9 speaker system that offers a balanced frequency response.

Power Output

Many sets of speakers offer a power delivery in watts. The numbers range from 100 watts to 1,000 watts, or more.

The more power output a speaker has, the louder it will be. Power output refers to the electricity amount the speaker can handle and transform into sound – you receive two measurements, RMS (root mean squared) and peak power.

RMS is the relevant rating to understand, as it’s the amount of power your speaker can handle on a continuous basis. Peak power, usually two to four times the RMS, is what your speaker can handle in a short burst.

While high numbers are good, we wouldn’t recommend anything over 600 watts. A measure above the number will distort the sound from the 6×9 speakers or leave the frequency range or bass behind.

Sensitivity Rating

Sensitivity is how much loudness a speaker delivers. The rating works directly with the power output, making it the perfect way to know the speaker’s sound.

Sensitivity also tells how well the speaker pair handles music volume. A sensitivity rating of over 87dB or decibels is enough to increase audio loudness well.


Frequency and output help you get more sound at the right volume but strive for clarity.

However, clarity is hard to pick because you must listen to what a speaker offers. But you can get an idea by carrying out a comparison of the sensitivity and power output to the frequency range.

For example, a 6×9 speaker with a wide frequency range, 400 watts of power, and 94dB is a decent model. But you’ll get a lot of distortion if the power output is too high and the frequency range is too tight. The factors will affect the bass, treble, and midrange sound quality.

Focus on crispness and clarity to reduce unwanted sounds and distortion.


Impedance is a quality that’s a determining factor whether you require an external amplifier. The higher the impedance level (in ohms), the more power a speaker requires to produce the same volume level. Understanding impedance helps you find the perfect speakers for your average usage.

High impedance speakers are easier on amplifiers and require less baseline power to function. A lower impedance speaker will be more demanding on your amplifier over an extended duration.

However, make sure the speaker ohms and amplifier ohms match.

Tweeter Quality

While technical sound factors are critical, you won’t enjoy them if the construction is poor. The shape and material of the tweeter have a direct impact on how your music sounds.

Tweeters reproduce the upper frequencies in music, including guitars, vocals, and other high notes that add life and sparkle to sound. The tweeter also plays vital sound staging and stereo separation roles, so music sounds like it’s coming from all around you.

The shape of the tweeter determines how it distributes the high frequencies in your vehicle. Different tweeter shapes provide the best possible performance out of materials at a price point.

Common tweeter designs include:

  • Cone tweeter: Usually found in factory speakers and have a paper megaphone to increase treble response.
  • Semi-dome tweeter: Found in low-cost speakers where the cone and dome are almost the same size.
  • Dome tweeter: A shape that helps radiate sound.

Tweeters also come in different materials, including beryllium, silk, polyamide, titanium, PET, and Mylar. Metal tweeters cut through the noise of highway driving with the windows down, while hard plastic and silk tweeters offer a natural sound to your music.

Woofer Quality

We recommend 6×9 speakers that use lighter materials such as fabrics, mica, polypropylene, or ceramic in the woofer. The materials ensure sound travels through the speaker while increasing the product’s durability.

Surround Quality

While surround quality is not as important as the tweeter or subwoofer, it offers an advantage when you have the right model. A surround made of rubber provides proper durability without affecting sound quality. Cheap models may have latex, foam, or cloth surrounds which are not as sound effective or durable.

Additional Features

The following additional features can also help improve your listening experience:

  • Pivoting tweeters: These are installable in multiple locations to drive sound directly to the listener’s ear. These tweeters ensure a more dynamic and lively sound performance.
  • Detachable tweeters: These are tweeters you install as a coaxial or component system. You don’t purchase additional tweeters when upgrading your car’s stereo system.
  • External crossovers: The crossovers help separate the audio channel into suitable ranges and corresponding components. High frequencies go to tweeters and low frequency to the woofers for clear sound.

Final Words…

There you have it, the best 6×9 speakers for bass. All the models provide excellent performance but an exceptional deep bass rendition. If you’re not convinced you can fit these beefy speakers in your vehicle, consider one of our favorite 6.5 inch speakers instead.

Each unit comes with the strength and rigidity to last for years with enough power to create a real difference in your car’s audio system and experience.

If the time to replace your old stock tired speakers is near, get a high-quality 6×9 speaker for bass today!
