1. Pioneer A Series – TS-A6995R 5-Way Speakers

Pioneer TS-A6995R review

Choosing a good set of speakers for your car can be a tough endeavor.  Every car is built differently.

And depending on the acoustical characteristics of a vehicle, a pair of speakers can sound terrible in one setting while it scores high in another one.

You might also find that classic music sounds great through a given set of speakers, whereas Hard Rock sounds flat and boring.

Pioneer has anticipated this issue and to overcome it, they’ve built their A-Series speakers with highly sensitive, rigid material and pre-configured them to cover a wide frequency range that will immerse you in a special realism inside your car.

These speakers are designed from the ground up to breathe a new life into your existing car stereo system.

You’ll be able to enjoy the crystal clear sound, powerful drums and beats, chunky guitar riffs and dynamic bassline that have always been part of your music, but have remained hidden behind your deteriorated factory speakers.

So what’s so special about these speakers?  Well, first of all, they come in a wide variety of designs, sizes and configurations.  If you’re an audio enthusiast looking for a better sound, you can get the components version which features separate tweeter, woofer, and crossover.

Separating all these parts allows you to place your tweeters in an optimal location within your vehicle for clearer audio with less distortion.  The only downside with component speakers is their relatively complicated and time-consuming installation process.

On the other hand, if you just want to swap out your factory speakers with a set of high quality aftermarket speakers, then you have more choice.  You can either choose 2-way , 3-way, 4-way or even 5-way design.

The “ways” refer to the number of drivers in one unit.  For example, 3-way or tri-axial speakers use 2-way design and add a third element called “midrange driver” which is responsible for enhancing coverage of the vital middle frequencies.

The plus one cone technology maximizes the cone.  4-ways design on the other side adds a fourth element called a supertweeter for even more detail.

On its own, Pioneer TS-A6995R is a 5-Way coaxial car speakers equipped with a multi-layer mica matrix cone that effectively maintains rigidity and internal loss, keeping distortion to an acceptable level so your bass sounds fuller at some extent without a dedicated external subwoofer.

Each of its woofers is attached to a midrange speaker, main tweeter, and two additional supertweeters for ultra high frequency reproduction and dispersion.  These speakers will certainly shine if driven by an aftermarket receiver or a powerful outboard amplifier.

There are no doubts Pioneer A Series – TS-A6995R speakers are the best 6×9 speakers in this category.  That being said, don’t strain your ears anymore with flat boring sound, when you can enjoy high quality music with these speakers.

2. JBL GTO Series – JBL Premium GTO939

JBL GTO939

JBL is one of the best rated car speaker manufacturers in the world.  They’ve been in this industry for a very long time.

They’ve mastered the art of providing speakers that can make a day-and-night difference given factors such as performance, reliability and cost.

Look around you, you can find that JBL speakers are nearly everywhere – your local venue’s public address system, your aunt’s deluxe home theater, your gym-friend’s headphones, your girlfriend or boyfriend’s Bluetooth speakers.

It makes complete sense that you’d also find them installed in vehicles as well.

The GTO939 speakers are the brand new speakers by JBL.  These speakers feature a poly-injected cone material that is extremely light, yet rigid so you can clearly hear and enjoy your tunes.  The cone’s lightness maintains bass while rigidity prevents distortion caused by cone flex.

Plus One® woofer-cone technology extends the cones surface area resulting in an increased bass output and higher efficiency without additional power.

The GTO speakers also feature 1″ inch edge-driven fabric-dome tweeter that is soft enough for comfortable listening, yet stiff enough to articulate higher frequencies up to 21 kHz.

The GTO 6 x 9 speakers come with 94dB sensitivity rating – the highest among all speakers we reviewed on this lineup and that’s what we love most about them.  High sensitivity rating means your speakers can respond to power applied to them in an efficient way.

The amount of power required to reach a certain volume shrinks by half with each increase of 3dB.  This means these speakers with 94dB sensitivity rating only need half the mount of power another set of speakers with 91db needs to reach the same volume.

These speakers can maintain high volume levels on a continuous basis without being damaged or without you experiencing distortion, due to their high sensitivity rating and high continuous power handling rating, that’s coming in at 200W per pair.

If you want to impress people with your sound system when you’re stopped at a red light, then these speakers are what you’re looking for.

The downside, however, is their relatively narrow frequency range of 46 – 21,000 Hz that is a little disappointing.  Some of the best car 6X9 speakers we’ve reviewed can reach as low as 27Hz and as high as 37Khz.  However, since both of these frequencies are far beyond human hearing, people won’t notice much of a difference.

So, If you’re looking for a great sounding speakers that’s going to be compatible with your current audio system, The JLB GTOs speakers are the ones for you.

3. Polk Audio DB Series – Polk Audio DB691 3-Way Speaker

Polk db691 Car Speakers

The Polk DB speakers are some of the best selling car speakers.  The Polk DB offers a stylish and elegant design. What they also offer is an inexpensive way to get your hands on the most brilliantly solid and reliable car speakers.

Polk DB speakers are some of the best-selling speakers on the market and for good reason.  They are profoundly above the norms and a result of the quality materials they are built with.

Their liquid-cooled 1″ inch silk/polymer dome tweeters use Neodymium which is a rare earth material that allows tweeters to deliver precise high-frequencies that shine through road noise and big bass in case your car is equipped with a powerful subwoofer.

Moreover, the 3/4″ dome super-tweeters expand your speaker’s high notes dispersion capabilities inside your vehicle. The built-in two-way crossovers provide better audio control redirecting the high and low frequencies to the proper drivers.

If that wasn’t enough, Polk db speakers are marine certified, so you can put them in your car, your boat, or your off-road vehicle.  And since they’re marine certified, the materials they’re made with are more durable so you can enjoy your music for many years to come.

Polk db speakers come in 2 or 3 way configuration and they’re available in all common speaker sizes including shallow mount versions.  They’re also  available in both coaxial and in component configurations.

These db Series speakers feature stainless steel mounting hardware and a great looking muscular ABS grilles that will add a super-stylish touch to your car’s interior making it look as good as it sounds.

If you’re looking for speakers that will sound phenomenal and for a phenomenal price, then look no further, because you’ve found the speakers of your dreams.

4. Infinity Reference X REF-9603ix

Infinity Reference X REF-9603ix

Infinity is another example of superior American manufacturer of loudspeakers.  Like JBL, and others we have reviewed, Infinity provides an above average sound experience.

They produce packages of a wide range audio applications, including in-wall home speakers, marine certified speakers, home theater systems and multi-channel surround sound home theater packages.

They also provide other audio products such as subwoofers, amplifiers, tweeters as well as bookshelf speakers.

The only thing I can imagine could be a problem is the low-end frequency, which is only at 46Hz.  It just feels like the bass is lacking fullness and depth you’d usually hear with speakers that have a deeper frequency response.

You don’t need to worry about this if you have a subwoofer, because subs are designed to cover low-frequency ranges that speakers can’t cover.

The best thing about these 6×9 rear deck speakers however is their highest sensitivity rating coming in at 94 dB.  To put it simply, these speakers can function at their best and effectively with less power when compared to speakers with low sensitivity.

The Infinity Reference X represents an unmissable opportunity for those of you who don’t want to get into the hassle of wiring and installing an external amplifier.  They can handle up to 100 watts of power on a continuous basis (RMS) and 300 watts at the peak.

You’ll certainly need an external amplifier to power these speakers in case louder volume and big bass are high on your list.
The Infinity Reference X 6.5-inch door speakers on the other hand are the best bang for your buck.

Just like their 6×9 counterparts, they lack a bit behind the competition because of their narrower frequency range of 50Hz – 21kHz.

However, their sensitivity rating coming in at 93 dB which is the highest among all 6.5 car door speakers, combined with their decent RMS power handling of 60 watts and 180 watts at peak make this set ready to shine out.

Product Specification

  • Top-mount depth : 3-1/16″
  • Design : 3-Way
  • Size : 6″ x 9″
  • Frequency response : 46-21,000 Hz
  • Power handling :
  • RMS  :  100 W
  • Peak  : 300 W
  • Sensitivity : 94 dB
  • Impedance : 4 Ohms
  • Warranty : 1 year
Infinity Reference X REF-9602ix 6"x9" 2-way car speakers
  • Peak Power: 300W
  • Frequency Response: 46Hz – 21kHz
  • Power Handling (RMS): 100W
  • Nominal Impedance: 3 ohms
  • Type: 6" x 9" two-way car audio loudspeaker

General Thoughts on 6×9 speakers

In addition to 6.5 car speakers, 6×9 speakers are another larger and one of the most commonly popular speakers size on the market.  They’re usually destined to be mounted on the rear deck or in pre-made enclosure boxes.

Because these speakers feature a larger woofer than other sizes such as 6.5 speakers, they are capable of reproducing stronger, fuller bass notes.

The quality of sound delivered by 6×9 speakers varies pretty widely depending on which model you buy.  Overall, a well-chosen set of 6X9 speakers will truly revitalize your music.
