1. Polk Audio DB6501 6.5-Inch – For Advanced Speaker Technology

View Product On Amazon

Every audiophile knows that Polk Audio is a big brand in the music system industry. And that they manufacture high-performing, top quality speakers. So there’s no reason why the Polk Audio DB6501 6.5-Inch 2-Way Component System is any different. In fact, the whole DB collection consists of nothing but the best models of all time.

But my goal is to only focus on these best component speakers. So first I would like to rave about the liquid-cooled silk/polymer tweeters. These use Neodymium magnets, the powerful ones. To give you accurate high-frequency sound reproduction!

Next in line is the addition of two crucial elements. These include the ABS grilles and stainless steel equipped mounting hardware (installing car speakers). So the car’s interior receives its fair share of visual appeal.

But here’s something that you might cherish the most, as a consumer. This best component speakers system is marine-certified. And that means it can withstand harsh or unfavorable environments. So don’t think twice before using it for vehicles, ATV, or boat.

What about the quality of music? Only after putting them to my testing did I notice the rich lows that the speakers deliver. Without any distortion! While the highs resonate with nothing but incredible clarity! So every single feature offers optimal technology to provide a dream-like music experience.

Installing car speakers is not an easy task. Especially when the system is not equipped with enough mounting hardware! But that’s something you need not worry about in this case. The Polk Audio DB6501 Component Speakers come with tough ABS grilles and adaptor rings. Plus, the complete mounting hardware has a stainless steel design. So you’re dealing with solid, well-constructed equipment that will last for many years.

Also, note that the backbone of the unit offers a highly reliable construction quality. To be more specific, the basket has a stamped steel acoustically inert structure. So you’re in for a treat with this car audio system.

But what’s the one thing that I don’t like about these speakers? The fact that the crossovers are not high-quality elements! And when that’s the deal, they tend to overheat.

The Polk Audio speaker surround can tolerate extreme conditions.
​The swivel cups enable mounting/placement flexibility.
The presence of heat sink means the most heat dissipation.

Buyer’s Guide to the Best Component Speakers


It doesn’t matter if you’re a first-time user or if you’ve already worked with component speakers. Every new experience always teaches you something or the other. Maybe the last time you did or bought something that, in hindsight, seemed like a huge mistake. So I thought it best to create this useful buying guide for you.

In here, I‘ve discussed everything you need to know about component speakers. Even though basic, the information will help you in making a well-informed decision. So if you want to avoid leaving out important factors, please keep reading.

So the first topic of discussion is this. The difference between the best component speakers and the best coaxial speakers!

Component Speakers vs. Coaxial Speakers

The article is dedicated to presenting the best component speakers, right? So I’m going to talk about how they have the upper hand over their coaxial counterparts.

Component music systems come with separate crossovers, tweeters, and woofers. So they have the ability to create excellent stereo-imaging. And this is what attracts audio enthusiasts the most!

On the other hand, coaxial speakers combine tweeter and woofer into one unit. And this applies to both the aftermarket and factory-installed units! In that case, the tweeter and woofer placement get compromised. Such arrangements make it impossible for the tweeter to not mess with the woofer’s sound wave production capacity. And no matter how hard you try, you can’t fix this particular issue.

So it’s a blessing in disguise when the tweeter and woofer are mounted separately. This way, each component has the freedom to operate without any interference.

On top of that, the thing about independent tweeters is that you can place them however you like. When tweeters are positioned correctly, they deliver the best sound-staging and imaging.

Here’s a downside. Component speakers perform exceptionally well only when paired with external amplifiers. But that doesn’t mean you can’t operate them on power-driven aftermarket head systems.

At the same time, this doesn’t take away an important fact. That component speakers shine the brightest with external amplifiers. So it’s safe for me to state that they’re able to withstand higher power than their coaxial counterparts.

Component Speakers: Common Ratings and Terms

When dealing with car speakers, you have to take certain factors into account. And these are nothing but common terms and criteria that are easy to understand. So allow me to explain further.

Power Handling

The power handling capacity of a speaker is the amount of power it can handle as well as operate at. It is denoted by 2 measurements, Peak and RMS. The former rating describes how much power the unit can withstand for short bursts. And RMS power is the power handling capacity on a continuous basis.

For the sake of comparing speakers, it’s the RMS rating that strikes as more important. And relevant too!


Depending on the power, a speaker’s sensitivity rating is the level of sound it can emit. The higher the value, the greater the efficiency of the unit!

Low-powered music systems perform well with a high sensitivity rating. And higher powered options with lower sensitivity! So what does that mean? It implies that the best component speakers offer the lowest sensitivity rating.

Frequency Range

This is measured in Hertz (Hz). How high or low the speakers produce sound at is known as the frequency range. The ranges begin from 20 Hertz and go up till 22,000 Hertz. This way, you can determine how high or low that particular unit can emit the sound at.

Component Speakers: Speaker Materials and Design

What’s the one thing that determines the quality and responsiveness of speakers? It’s the woofer. The highest-rated component speakers are models equipped with stiff yet lightweight woofer cone. In that case, it’s the polypropylene material you need to look out for!

Additionally, woven fabrics like Kevlar are present in high-quality speakers. Even titanium and aluminum are excellent options for high-end units.

Woofer Surround

Another significant aspect is the invaluable woofer surround. This particular component also affects the sound quality of speakers. Here, the material used should be free moving, lightweight, and durable. Only then does the woofer move with minimal energy!

Let me also bring durability into the picture. With time, humidity and signs of wear tend to increase. And these changes contribute to cracking and breaking the useful woofer surround. So at such times, if the material is durable, as is the case with rubber, your speakers will last longer.

On the other hand, cloth or foam woofer surrounds don’t offer an extended lifespan. Plus, they offer poor performance as well.


All high-quality component speakers feature crossovers, right? What external crossovers do is reduce the level of distortion. By separating the different frequency inputs!

More often than not, signals have a tendency of crossing through the coated wiring. As a result of which distortion comes into action. So to reduce this distortion, manufacturers equip speakers with a crossover system.


My Choice: Polk Audio DB6501

I would like to conclude by sharing the ultimate pick in the category of the best component speakers. After all the researching and reviewing, there is one model that ranked the highest. It’s the Polk Audio DB6501 6.5-Inch 2-Way Component System.

The marine-certified speakers come with phenomenal tweeters. Ones with exceptional neodymium magnet! To provide nothing short of detailed, clear highs. On top of that, the cone structure is lightweight and stiff. And this is useful in delivering big sound. That too with minimal distortion!

Other useful additions include voice coil and heat sink. The former takes care of higher power handling. While the latter encourages heat dissipation! As for durability, the basket is well built with a rustproof coating. So the manufacturer has left no stone unturned to add a reliable product to the audio industry!
