What Makes the JBL CLUB6520 6.5 coaxial Speaker So Good? 

Works With Most Stock Head Units 

Upgrading to 6.5-inch speakers often warrant a head unit replacement, but this isn’t necessarily the case with the JBL CLUB6520.   

Because it’s aimed towards value-oriented users, the JBL CLUB6520 won’t need an upgrade. You can use these 3-ohm speakers with your factory wiring. It doesn’t matter how thin it is. As long as it’s in good condition, then you’re good. You’ll be able to provide all of the power that you need to get the most out of the CLUB6520 6.5 Coaxial Speaker via your car’s head unit out of the factory.   

Also note that, while the JBL CLUB6520 6.5 Coaxial Speaker was built with factory head units in mind, it’ll do a lot better if paired with a proper amplifier.   

This means that it’s a great option for both audio enthusiasts and beginners alike.

Made Out of High-Quality Materials 

The JBL CLUB6520 was designed with high-quality audio in mind. Because of this, it comes equipped with a polypropylene cone that’s coated with a UV-resistant material with acoustic dampening. This allows it to deliver clean and crisp sound quality without compromise, regardless of how hot and how humid the environment is.  

Patented Cone Architecture 

One of the biggest reasons why the JBL CLUB6520 is able to punch well above its weight is because of its cones.  

With its patented design, the Plus One™ Woofer Cone architecture enjoys a much wider speaker-cone area compared to other speakers. As a result, it’s capable of delivering better highs and lows, leading to better overall music.  

Attractive and Easy to Install 

The JBL CLUB6520 Coaxial Speakers isn’t the kind of 6.5-inch speakers that you’d be afraid to show off. As a matter of fact, the contrary is quite true. They’re easy to install, with JBL’s signature red accents shown off prominently on the attractive black grilles.

You won’t have any problem fitting these 6.5.-inch coaxial speakers inside your vehicle, regardless of whether you have professional help or not.   

The CLUB6520 is designed to fit on just about any road-worthy vehicle.


  • Affordable and reasonably-priced

Is the JBL CLUB6520 6.5 Coaxial Speakers Worth the Money? 

Coming from stock speakers, anything is an upgrade. You can buy the first 6.5-inch speakers that you see and you’ll see a significant improvement in audio quality. But, the thing is, not all of them will give you a good value of your money.   

With that said, the JBL CLUB6520 screams value.  

From its extremely attractive price point down to the fact that it works well with factory head units, which makes it easy to install on your own even if you have little to no prior experience, the CLUB6520 6.5 coaxial speakers is definitely worth your money.   

And, we haven’t even factored in its high-quality construction yet.   

Despite being relatively affordable, these two-way coaxial speakers are made out of high-quality materials. This includes UV-resistant polypropylene woofers that are designed to handle constant heat, humidity, and vibrations. It also comes with PEI balanced dome tweeters for optimal high-frequency performance.   

As an added bonus, the JBL CLUB6520 6.5 Coaxial Speakers has a relatively wide frequency response range that starts at 55 hertz and goes up all the way to 20,000 hertz.  

Sure, the JBL CLUB6520 6.5 Coaxial speakers isn’t perfect. It’s got a couple of flaws. In particular, it could have used more power if only for better bass performance. However, to point that out as a significant disadvantage would be nitpicking already. Because, as it is, you can’t really expect loud bassy performance from such a well-balanced pair of 6.5-inch speakers.   

Everything the JBL CLUB6520 does is either good or great, and while it’s not the best, it’s certainly right up there, especially in its price range.

Final Thoughts

Sometimes, all a product has to do is to be good at everything even if it’s not great at a particular thing.   

JBL CLUB6520 6.5 Coaxial speakers is a good example of that.  

A significant improvement over stock speakers, the JBL CLUB6520 is great if you’re looking for the better sound quality on your daily drives. This is especially true for older vehicles with speakers who may have already blown as a result of the use that it’s had over the many years of service the vehicle has given to you.   

At the same time, the CLUB6520 is a great gateway option to better music.  

Easy to install, affordable, made out of high-quality materials, and with excellent performance, the JBL CLUB6520 6.5 Coaxial speakers is a very good pair of 6.5-inch speakers. The price point you get for the quality is a definite plus.
