A Rundown Of The Best 6x9 Component Speakers:
These excellent value Kicker 6x9 component speakers are our favorite of the tested models as they represent quality, great sound, practicality and surprisingly - the lowest price tag of the lot. The Kicker 40CSS694 speakers are very hard to fault by our reviewers and very easy to praise!
When it comes to power output, these speakers score the highest of the lot, being able to handle a whopping 150 watts RMS. Furthermore, they also have the lowest bass response, reaching 30Hz on the low end; and a high register of 21kHz through the tweeters - which additionally, have 0dB, +3dB and +6dB attenuation controls on the crossover unit. Regarding sound reproduction, the Kicker Extended Voice Coil (EVC) system gives an overall smoother and rounder sound than its predecessors.Additional specifications include an impedance of 3.3 Ohms, a speaker sensitivity is 90dB.
The speaker domes are constructed from titanium and the woofers come standard with chunky Fort-Knox style grills that assist to protect your speakers, hopefully well past their 1 year warranty! The mounting on the woofer speaker depth is a little bit shallower than the Morel Tempo Ultra 692, requiring a cavity that is at least 81mm (3 3/16”) deep.
All-in-all, the Kicker 40CSS694 is a great overall pick, matching or even surpassing similar speakers in power, frequency response, and value. And with a bass frequency as low as 30Hz, if you choose not to include a subwoofer in your system, you'll still being able to move some serious air with this bangin' set of speakers.
- Chunky 150W RMS and 450W maximum power rating
- Broad frequency response range (30-21000Hz)
- Lowest price tag!
- Lower range of speaker sensitivity (90dB)
Memphis Audio 15-PRX69C
Memphis Audio is a brand that specialises in premium car and marine audio amps, subwoofers, speakers and accessories.
The Memphis Audio 15-PRX69C speakers are the slimmest in our tested range with a depth of only 76mm (3”). They are also carry the lowest power rating of the lot by some margin, at 60W RMS. Even so, the Memphis Audio 15-PRX69C's could do a fair job at replacing your stock car speakers or pairing with the output of a standalone head unit, as you could move these polypropylene cones sufficiently without an outboard amplifier. If you are on a budget, these are a worthy choice for upgrading your stereo, without forking out for extra hardware and installation costs. Additionally, being reasonably priced, they are very accessible and represent immediate improvement to any system.
These speakers have a sensitivity of 90dB and a frequency response range of 51Hz – 20kHz, which sacrifices extreme top clarity and moves less bass than any other speakers reviewed. This however can work to an advantage again, with wiring these speakers up to a head unit without an outboard amplifier, as the limited bass response will not drain the stereo’s wattage output, giving an overall full sound, especially in smaller cars. The separate tweeters and crossover that come in the box will allow extended versatility in customizing your car audio soundscape.
- Great for small cars
- Will perform wired straight into a stereo head unit
- Very affordable
- Slimline design
- Limited frequency response range without additional subwoofer
- Low power handling
Infinity Reference 9620cx
With the Harman Infinity name being in the speaker industry for nearly seventy years, you can rely on experience with these Infinity Reference REF-9620cx component speakers.
For a mid level speaker - they have an impressive continuous power rating of 125W RMS. Furthermore, the frequency range of 46Hz-21kHz fits nicely into your extended system along with amplifiers and subwoofers. Their slimline design, with a mounting depth of only 77.8mm (3.18”) also allows for installation in tight spaces. These speakers also have a high sensitivity compared to the other speakers we've reviewed, at 93dB.
Worth noting is that the REF-9620's run at 3 Ohms, as opposed to the more popular 4 Ohms, so matching to an appropriate amplifier is (always!) important for optimum performance and safety of your speakers.
Importantly, the speakers do not come standard with tweeters in the box, so it is likely that you will have to fork out some extra cash, most likely for the tweeters in the Harman Infinity range: the REF-275tx set which feature textile composition, plus a crossover unit to round off this section of your complete car audio system.
- Long standing, experienced and respected brand
- High sensitivity and power
- Tweeters and crossover unit sold separately
- Requires specific outboard amplifier to run at 3 Ohms
Morel Tempo Ultra 692
The Morel Tempo Ultra 692 is the largest of the Tempo Ultra series and understandably the most expensive. In fact, it is the most expensive of all the component system speakers that we explore here, at roughly three times the price of the lower price competitors.
Although assembled in China, these speakers are top quality and undergo intense quality control on the production line. The woofer cones are made from sparkly treated paper and the woofer surrounds consist of butyl rubber, while the voice coil wire is copper. The magnet in the woofer is made from high-grade ferrite while the external tweeter magnet is constructed of neodymium, with the tweeters included in the box as standard. This speaker is the deepest (in size) of our explored speakers with a mounting depth of 85mm (3.35”), potentially making it difficult to fit into narrower speaker cavities.
Whilst some sources suggest the frequency range to go as low as 35Hz, the official Morel specifications list indicates a frequency response of 50Hz – 22kHz. Other specifications include : A standard 4 Ohms impedance, a speaker sensitivity of 91dB and an impressive 130W RMS, meaning these speakers can get loud!
For pure quality, the sound and performance of these speakers is, quite simply, hard to match. But note - they aren't for the faint of heart, given their significantly higher price-tag, and are more geared towards the audiophiles amongst us who want the best and are willing to pay for it.
- Quality construction and materials
- Aesthetically pleasing
- Limited warranty period
In order for you to make a more informed decision when looking for the best 6x9 component speakers for your car audio system upgrade, we hope our comparative research assists you in making the right decision for your car and budget.
All-in-all, we feel that the Kicker 40CSS694 set is a great overall pick, matching or even surpassing similar speakers in power, frequency response, and value. And as mentioned above, the low bass frequency of this set will allow you to move some serious air even without a subwoofer.
Otherwise, the Memphis Audio 15-PRX69C and the Harman Infinity REF-9620cx series are pretty hard to separate even if, other than the shared slimline design, the specifications are significantly different. The Harman Infinity range is a more boutique range than the Memphis Audios, potentially requiring additional money for tweeters and crossovers, to allow the speakers to run at their optimum performance levels. Worth noting is that the Infinity's have more than twice the power rating of the Memphis Audio's. However, this makes the latter easier to integrate into smaller systems and cars, making them a good budget upgrade as opposed to the former’s demand for more money and hardware.
Finally, as mentioned, for pure quality, the sound and performance of the Morel Tempo Ultra 692 speakers is comes out on top. But, given their significantly higher price-tag, these are ultimately geared towards the true audiophile. So if you have sufficient room and plenty of money to throw around, not just for the best 6x9 component speakers but also for subwoofers and amps, be our guest - these premium speakers will surely please!
For a rundown of our choice of best speakers in other ranges, see:
Audio companies generally advertise their products using terms like "MAX" or "Peak power".
Forget about all that. When we're discussing power, RMS is the only value that lets you make any sort of meaningful comparison between two products. Why is that?
Well, RMS stands for Root Mean Square. No math lessons here; this just means that RMS measures how much continuous power a component can handle safely.
Peak power is how high the system can go at maximum output, but it can't stay at that wattage for long without causing problems.
That's why devices that advertise "peak power" are being a little misleading. What's really important is sustained sonic output for an indefinite length of time.
RMS lets you quickly and easily compare power outputs between components.
This means a speaker with 200-watt MAX but only 60-watt RMS is less powerful than a speaker with 100-watt MAX and 80-watt RMS.
Range / Response
When we start talking about speaker range or frequency response, you might have a general idea of what we mean.
On the surface, it's pretty simple. Range is a measure of how much of the audible sound range the speakers can produce. It's measured in Hertz (Hz), with low numbers being long, deep tones (like the boom of a drum) and high numbers being shorter, sharp tones (like the singing of a bird).
Obviously, we're only concerned with the portion of the Soundwave we can hear. Human ears are capable of responding anywhere from 20Hz to 20,000Hz (or 20 kHz).
Range is a simple concept to understand, yet difficult to master. If you want to fully appreciate the implications of range and how it applies to audio equipment, you have to dive into some complex mathematics. That's beyond the scope of this article.
For now, just remember: Range is a useful way to measure how much of the audible spectrum a device can produce.
Please note - it doesn't tell you anything about the quality of that sound! Don't make a purchase based entirely on response.
This fancy term just means how much AC resistance exists in the wiring of the speakers. Please note: Different frequencies can have different impedance values.
Generally, most loudspeakers will have resistance that ranges between 4- and 8-ohms. As long as your speakers have similar impedance to your amp, you'll be fine.
A higher impedance means that an amplifier will have to push more voltage to create the same sound quality. On the other hand, it also means a component can handle more juice without taking damage.
As long as you make sure these values are in alignment, you shouldn't worry too much about impedance.
This isn't how fragile or delicate your speakers are; nor does it have anything to do feelings. This is a universal metric that simply tells you how much sound pressure (loudness) an audio device will create at a stated distance on a single watt.
What does this mean to you? The more sensitive your speakers are, the less power they require to produce the same amount of volume. Basically, it's translating more of that raw power into crisp audio goodness!
My first car was a 2005 Subaru WRX. I loved her, but she had very shallow door panels and it was a struggle to find speakers with a profile narrow enough to fit.
Depending on your ride, you'll have more or less room to work with as you build a stereo system. Make sure you don't make the mistake I did and assume depth is universal - you could save yourself some serious money and a lot of heartache.
Work components around your car; don't work your car around components.
How much room will you need to mount the speaker in your vehicle? What's the difference between "top mount" depth and "bottom mount" depth?
Top-mount depth is how much room the top of the speaker needs from the point of installation. This is how far it 'juts' out into your car interior.
That means bottom-mount depth is how much room the bottom of your speakers need to clear the interior of your dash or panel.
For simplicity's sake, in our reviews we focus on the more commonly available measurement: top-mount depth.
