6.75″ Coaxial Speakers

Our Pick

Kicker 47KSC6704

Power/Per Speaker: Peak 200W, RMS 100W
Frequency Response: 40 Hz – 21 kHz
Sensitivity: 90dB
Top Mount Depth: 1.81”

This Kicker 6.75” pair of coaxial speakers are a good option for people who don’t want to miss out on midrange details while experiencing the pounding bass of the soundtrack. Also, with the price tag it comes we think you can’t go wrong with this Kicker!

These Kicker speakers are also low profile and have even shallower top mount depth than any other on this list. The protrusion of its tweeter is minimal as well.

The peak power of this speaker is lower than 46CSC674. However, it doesn’t matter much most of the time because both boast the same RMS values. The overall sound quality of these coaxials is very impressive. They can create a concert-like ambiance without sounding roughly loud.

The construction of the speaker is also worth mentioning. The polypropylene woofer cone with rubber surround and silk dome tweeter guarantees that your coaxial sound experience remains intact even after years of use.

Runner Up

Hertz X 170

Power/Per Speaker: Peak 100W, RMS 50W
Frequency Response: 60 Hz – 21 kHz
Sensitivity: 93 dB

The Hertz Uno Series, particularly, has received a lot of love from the masses. It is, therefore, no surprise that we’re practically smitten with the X 170. It sounds good, has a gorgeous chassis, and comes at a reasonable price tag. Just a perfect pick for your door speaker replacement. 

These 6 3/4 speakers look immaculate on paper. And guess what, they sound just as great. When you encounter the X 170 package, the realization that it is a gem is almost automatic. Its speakers’ have a shallow profile and industrious bodies are a sight to behold.

They would look great in any cabin space. Each is fitted with a delicate water-repellent treat paper cone. It creates basic yet rich vibrations which are then diligently pushed onto the thermoplastic polyurethane surround. This process produces beautifully crafted notes which are, to say the least, music to any ears.

A built-in crossover works great in sorting out the frequencies between relevant drivers. The highest bunch is driven through PEI dome tweeters which prove very potent. Their little bodies embrace sound to output clear, spicy highs that seemingly capture a whole lot of details.

The speaker baskets are covered by abrasion-proof dust paint to guarantee longevity. Tin-plated high current terminals are tough enough to work sufficiently years on end. In a nutshell, the X 170 coaxial package delivers music with a prowess hard to come by.

Rockford Fosgate Punch P1675

Power/Per Speaker: Peak 120W, RMS 60W
Frequency Response: 60 Hz – 26 kHz
Sensitivity: 89 dB
Top Mount Depth: 2 1/4”

It’s impossible to notice how much effort was put into building P1675 6.75″ speakers. Their bodies are put together thoughtfully; each part meant to endure long hard performance sessions.

Rockford speakers are the type that drips legitimate swag; they always look flashy. That case remains so with the P1675 pieces. But looks aren’t the only thing going on for them. They sound spicy, crispy, and well, insanely transcendent.

Looking at the P1675 speaker, you can’t help but get drawn to its unusual surround. By unusual, I don’t mean bad. Far from it, these speakers’ surroundings are something else.

Using the vertical attach surround technique, Rockford made sure the Butyl rubber surrounds sit in a manner that optimizes cone performance. The mineral-filled polypropylene cones stand up to the task and ex-cur freely for unsurpassed performance. That, paired with each speaker’s 60 Watts RMS, the resultant sound is not only loud but is also heavily decorated.

FlexFit basket design sees to it that the speakers serve for extended periods of time. PEI tweeters offer much support to mid-range performers. They even feature a super tweeter.

These tiny players sure can hold their own even in the toughest sonic milieus. That said, their highs are immaculate. The bass is deep and heavy, the highs are crisp and clean, what more could you want.

Also Great

Kicker 46CSC674 CS Series

Power/Per Speaker: Peak 300W, RMS 100W
Frequency Response: 40 Hz – 20 kHz
Sensitivity: 90dB
Top Mount Depth: 1 7/8”

If you are looking for a low-profile coaxial set of 6.75” speakers that can deliver the clean bass and boast durable construction, this Kicker pair is certainly worth considering. With its 100W RMS rating, it is good enough to produce thumping low-end reverbs you like as a bass enthusiast.

Its construction is also quite remarkable. From top-quality neodymium tweeter magnets to stamped-steel framework with sturdy polypropylene woofer cone, this Kicker speaker sports quality construction through and through.

We also like its hassle-free installation— thanks to its low-profile design. It has a shallow mounting depth with tweeters that don’t protrude like other 6.75 coaxials. Therefore, you can install them without removing or modifying the factory-fitted grills.

Kicker 43DSC6704 D-Series

Power/Per Speaker: Peak 240W, RMS 60W
Frequency Response: 40 Hz – 20 kHz
Sensitivity: 90dB
Top Mount Depth: 1 7/8”

If you want real, authentic dynamism, then you should hurry up and get yourself the Kicker 43DSC6704 6.75″ speakers. Considering how affordable this package is, it’s hard to believe it can blow the roof off.

However, these speakers are easily the best within their price range. They feature special additions to refine their output. Ultimately, cheap has never sounded so good.

Let’s kick this off by mentioning the speakers’ super-thin mounting profiles. These will fit in pretty much anywhere; even the tweeters lay neatly with naught surface protrusion. Installing them may be easy, but just how good do they sound? Well, the answer is simple; they sound phenomenal. With polypropylene cones and UV- treated polyester foam surrounds, these speakers are master creators. It also helps tremendously that each speaker has a 60 Watt RMS which transforms to a max of 120 Watts.

A stamped steel shell gracefully houses all the speaker elements. High-sensitivity motors see to it that the details are not only refined but are also crystal clear. Balanced PEI dome tweeters enrich the already superior sound with their exquisitely spun highs. NVX Sound dampening drains out road noise for optimal gratification.

Even more impressively, the speakers come paired with DX amplifiers. That allows for extremely loud results, and that’s always a plus in any vehicle cabin. This package clearly gives its users very little to complain about. Best of all, the eventual sound is nothing short of platonic.

Budget

Kenwood KFC-1796PS

Power/Per Speaker: Peak 330W, RMS 100W
Frequency Response: 72 – 24k Hz
Sensitivity: 88 dB
Top Mount Depth: 1 15/16”

Replacing those tacky OEM vehicle sound systems can be daunting. Once you decide to make such a move, you only hope to get the best out of it. Well, Kenwood speakers are a very plausible resolution; especially because they are affordable and kick-ass performers.

That said, we present to you the Kenwood KFC-1796PS 6 3/4 speakers. They rock long and hard, and they do so without hurting your bank account.

Imaging is everything when it comes to speakers. The KFC-1796PS does a whole lot of that and it does so impeccably. I won’t lie, something this amazing at such a low price is literally a needle in the haystack. A paper woofer cone, with the help of a rubber surround, rocks each speaker hard.

These flush-mount speakers are nothing if not bad-ass. They play around the sound spectrum with such elegance you can’t help but jump right in as well. They can also play pretty loud; am talking concert-level loud. What else would you expect from a 330 Watt peak power capacity gadget? Nothing less, that’s what.

This system brings you tweeter power like no other. Its paper cone tweeters are fierce performers. As if that’s not enough, Kenwood went on and threw in a ceramic super tweeter into the package. That’s right, it only gets better. That translates to crazy, detailed, spotless highs.

4 Ohms impedance lets you test new waters with this one. I can only say one thing in regards to this package; do go crazy with it, it’ll hold out just fine.

Budget

JBL GX602

Power/Per Speaker: Peak 180W, RMS 60W
Frequency Response: 50 – 21k Hz
Sensitivity: N/A
Top Mount Depth: 2 1/16”

Quality sound is a rarity, and it takes a lot to concoct. JBL seems to recognize as much because that’s all you get with the GX602 speakers. Driven by polypropylene Plus One woofer cones, they pick the smallest of details with no sweat.

3 Ohm DCR voice coils go on to draw tremendous amounts of power from relevant sources with naught possibilities of burning out.

This makes them efficient performers regardless of the volume. Each speaker runs 60 Watts which doubles to 180 Watts at its peak. Now, if just one can juggle that much power, imagine what you get from a pair of these ferocious speakers.

The soft dome tweeters are no different from their mid-range counterparts. They possess a tweeter deflector quality that optimizes off-axis sound performance. With that big of a contribution to the rich mid-range notes already coming from its speakers, the resultant sound is phenomenal.

All in all, the JBL GX602 package is one of the most promising budget 6.75″ car speakers you may ever come across. If you find it, I suggest you give it a shot – you can also try something similar in the best 6.5 car speakers department.

6.75″ Component Speakers

Our Pick

Kenwood Excelon Reference XR-1703HR

Power/Per Speaker: Peak 180W, RMS 45W
Frequency Response: 25 – 48k Hz
Sensitivity: 83 dB
Top Mount Depth: 2 3/8”

We’ve had to sort through an endless string of phenomenal speakers in search of the best 6.75″ component speakers. Believe me when I tell you it’s not easy. However, once we landed on the Kenwood Excelon Reference XR-1703HR speakers, we were sold.

Its glistening glory is something of a spell; resounding in both its appearance and audio magnificence. Let’s take a look at its most prominent aspects.

Much praise treads on the heels of the Kenwood XR-1703HR – check the full review; more so its legendary power handling capacity. A single component from this package runs on 180 Watts at its peak. In other words, two of these components hit unbelievable heights running 360 Watts at maximum. That’ll wipe the roof right off your cabin.

The XR-1703HR components are tailored from a supreme collection of materials. This makes them adept and very durable. The woofer cone, for instance, is molded from woven fiberglass. These palpably delicate devices are hosted in heavy-duty aluminum die-cast baskets with vastly obstinate faculties.

Each speaker features an optimized equalizer shape. Often, the audio output attained from this package is well balanced and polished. The highs, the lows, and the mid-ranges all integrate to form a pretty euphonious effect. For more component systems see our review of 6×8 car speakers.

Now let’s talk tweeter power; the XR-1703HR features the soft dome kind. They feature inline crossovers which help them focus more on their musical strongholds. The tweeters hit highs with evident prowess. This would explain why the system is Hi-Res compatible.

Ultimately, reproduction is crispy and crystalline. And all that is besides the fact that the XR-1703HR components have gorgeous bodies. In this case, all that glitters is indeed gold.

Bang For The Buck

Kicker 47KSS6704

Power/Per Speaker: Peak 250W, RMS 125W
Frequency Response: 35 Hz – 21 kHz
Sensitivity: 91 dB
Top Mount Depth: 1.87”

This 6.75” component system consists of two tweeters, two woofer, and two crossovers. Like other Kicker speakers, this system also boasts extraordinary mounting flexibility— thanks to its relatively shallower top mount depth.

The polypropylene woofer cones are internally dampened and feature a rubber surround. These construction attributes let them throw up midrange and low-range (bass) frequencies with quite a balance.

This component speaker set also manages to create an expansive sound design due to its powerful magnet and Extended Voice Coil (EVC) technology. The speaker can blast loud audio without compromising on the cleanliness of the bass.

If you are looking to get an upgrade on the stock sound of your vehicle without straining your budget, this Kicker component speaker won’t be a bad idea.

Runner-Up

Kicker 41QSS674 Q-Class

Power/Per Speaker: Peak 200W, RMS 100W
Frequency Response: 40 – 22k Hz
Sensitivity: 87 dB
Top Mount Depth: 2 9/16”

The Kicker 41QSS674 is a shoo-in. Sitting right near the top of the food chain, this system could eat its contenders alive. Kicker’s Q class series has been the talk of the industry; their featured speakers are fierce.

Now the 41QSS674 is in every way tumultuous. Built from top-rated materials to reproduce superior resonance, there’s only a handful of others like this in the industry.

Right off the box, you can tell this system carries insane amounts of grit. One look at the speakers is enough to put your mind at ease. Why? You’ll know you made the right choice. This Kicker 6 3/4 speakers feature Kevlar impregnated polypropylene cones with stiff rubber surrounds.

This light yet sturdy combination of materials creates that propitious setting for top-notch reproduction. With a peak power handling of 100 Watts (per speaker), God knows you need competent elements for optimal output.

Teton dome tweeters work tirelessly to keep up with their masters. Although this system is best known for its impeccable mid-range faculty, its tweeters hit up the highs with immense precision. This result is a pleasant combination of notes all across the spectrum. The harmony is simply to die for.

Cast aluminum baskets and crossover scream longevity. The baskets do a great job of keeping everything safe. Duo-wave spider uses design to maximize reproduction. The grilles look great. They are also designed for easy installation.

Budget

Hertz Uno K 170

Power/Per Speaker: Peak 280W, RMS 70W
Frequency Response: 55 Hz – 23 kHz
Sensitivity: 93.5dB
Top Mount Depth: 1.81”

If you don’t want to spend too much to upgrade the factory sound, consider this component speaker system by Hertz. With two woofers and tweeters, it has an integrated crossover. Its output is not as powerful as other top-of-the-line 6.75” component speakers. Nonetheless, they do the trick.

Its PEI dome tweeter with integrated crossover ensures you get to hear crisp highs. On the other hand, the woofers with treated paper cones and foam surround catch and deliver every low of the soundtrack. Getting such full-spectrum good sound happens very rarely with budget speaker options.

We also like this Hertz component speaker set because it is not inflexible with its installation like various other component systems. The manufacturer has devised its tweeter installation procedure that is in line with more than one mounting style.

Also Great

Memphis Audio PRX60C 6 3/4″ Component Speakers

Power/Per Speaker: Peak 100W, RMS 50W
Frequency Response: 72 Hz – 20 kHz
Sensitivity: 88dB
Top Mount Depth: 2.5”

This Memphis component speaker package has an external crossover with its two tweeters and woofers. If you think that your stock amp can’t handle more powerful speakers but you still want better sound than what you are getting now, try these speakers. Their 50W RMS output is in line with the power delivery of many stock head units.

Another thing that makes this Memphis option stands out among other component speakers is its consistent construction. Both its woofers and tweeters are made of the same material i.e. polypropylene. Moreover, the woofer has a polyurethane surround that enables the woofer to continue to blast throbbing lows.

You might have to make some grill modifications to install this component speaker system. However, its impeccable sound staging that covers all highs, mids, and lows is worth the installation effort.
