15 Best 6.5″ Coaxial Car Speakers in 2021

A coaxial car speaker is a boon for your car if you love listening to music but find that the sound quality and loudness of the stereo leave a lot to be desired. That’s because it combines the bass speaker (normally found in an amplifier or home theater system) with a tweeter so that both noise frequencies are produced and amplified at the same time. It also has high sensitivity meaning that it can play loud without distorting.

There are several types of 6.5″ coaxial car speakers available in the market today each offering distinct performance characteristics that appeal to different kinds of consumers.

Considering that some of them are designed for a specific type of vehicle, buyers should take extra care to ensure they choose the right speaker for their needs before making a purchase.

Make sure you conduct enough research before buying a speaker for yourself or for your vehicle. Below is a compilation of 15 top-quality 6.5″ coaxial car speakers that you can select from. You’ll thank us for it later!

1. ALPINE R-S65.2 R-SERIES

The R-S65.2 is ideal for tighter installations since it does not use heavy magnets like the previous generation of Alpine speakers. Because of this, it’s even lighter at only 4 pounds! It’s smaller than the Alpine R-S965.2 which means it can fit into extremely tight spaces, for instance, in cars where space is at a premium. It comes with huge improvements which makes it so awesome!

The cone technology used in this model is still very unique. The newly designed cone is smaller yet has the same power handling capability as its predecessor but with more efficiency and excellent detail clarity. The revised motor control of the R-S65.2 plays an integral role in the overall performance of the speaker used to modify the bass output. There are two parameters that can be adjusted by switching individual coils on or off: low-pass crossover and high pass crossover.

The use of motor control over the bass output means more listening freedom with no need for a separate head unit. The R-S65.2 uses an aluminum magnet for better heat dissipation and more lightweight construction. 

2. NVX N-SERIES

The NVX N-Series coaxial speakers are the perfect solution for serious audiophiles. They’re built with an integrated filter network to reduce distortion, have a high-temperature KSV voice coil to dissipate heat, and incredible linear movement that lets you hear every detail of your favorite music. This speaker is surely one of the best investments for your music collection today.

The sound is so clear and pure; very detailed but not tinny sounding at all! These speakers will take all the songs you’ve ever heard to the next level. The highs are crisp and piercing while also being smooth and musical. The midranges are fleshed out and deep. The bass is tight, punchy, and incredible, no matter what kind of music you’re listening to. And it’s not just the quality of the speakers that’s impressive, it’s also the quantity: 2 speakers, a center channel, and a subwoofer.

Unlike most surround sound systems that use separate components that require wires to connect together, the NVX N-Series is designed to work together perfectly. This means that you can easily play your favorite music through one source and have it played back through all speakers as well as the subwoofer. And because these surround sound systems are sold as a package, installation should be quick and easy.

So if you’re looking for the best combination of quality and value for your dollar, make sure to check out these great coaxial speakers from NVX! You won’t be disappointed.

3. KICKER 43CSC654

The Kicker 43CSC654 speakers can seem a little bit heavy. This is because they are made from steel. But this steel content makes them feel really solid.

This feature is only seen in higher-end coaxial speakers which the Kicker 43CSC654 is not due to its affordable price. 

EVC allows for improvements in voice coil inductance and voice coil diameter. The beveled pole piece is also another feature that makes the Kicker 43CSC654 speakers stand out.
