Upgrading your car's factory speakers with a pair of the Best Coaxial Car Speakers will give new life to your daily driving. Coaxial speakers combine the woofer and the tweeter onto the same axis. Compared to component speakers, where the tweeter and the larger woofer are separate and need to be mounted separately. Coaxials are a combo package. This allows the projection of a full range of sound and frequencies from 'one' speaker. They’re easier to install and easier to wire. You can even replace component speakers with coaxials if you’d like. This type of speaker is arguably the most popular speakers on the market.

There are a number of benefits to upgrading your vehicle's stereo with a set of aftermarket coaxial speakers. Car manufacturers don't focus on their speakers as much as they should. In most cases, the factory speakers that come with your car are cheaply made. They aren't built for audio performance either. Aftermarket speakers are made with better quality materials than OEM speakers. They have a longer lasting life, and in most cases will provide improved audio performance too. There's also a number of added benefits and features to aftermarket speakers, like weatherproof and water resistance. And one of the best parts about aftermarket speakers is that they're affordable. You'll find that in most cases, replacing your car's speakers with OEM units is more expensive than a higher quality aftermarket coaxial speaker.

Here is a list of 2017's top rated and reviewed 6 1/2 inch coaxial car speakers to help you choose the best products for your car's stereo:

Before you scroll down to our full list of 6 1/2 inch coaxials, make sure you know the difference between a coaxial and component car speaker:

Component Speakers are typically a pair of tweeters and mid-bass drivers (speakers) that are matched with a crossover that limits the frequency range each speaker reproduces. You can tell if your car has components if you have more than one speaker for each channel, or if the tweeter is separate from the mid-bass driver. Usually component sets are in the front of the vehicle.

Coaxial Speakers have the tweeter, mid-bass driver and the crossover mounted together in one space saving speaker. They are very popular because they are much easier to install and don’t take up as much space as the component set. Coaxial speakers are usually found in the rear of the vehicle.

Best Car Speakers: Common Speaker Terms & Ratings

When comparing and choosing coaxial speakers on today's market, m-segment.ru takes into consideration several key criteria: Lets define a few common criteria and terms that are compared when rating a speaker:

Power Handling: Power handling is the measurement a manufacture gives to rate how much power a speaker can handle and operate at. It is given by two measurements, RMS and Peak (or MAX). RMS Power rating is the amount of power the speaker handles continuously, while the Peak Power rating is the amount of power a speaker can handle in short bursts. When comparing speakers, RMS Power is the more relevant and important rating to look at.

Sensitivity: The speaker sensitivity rating is a measurement of the amount of sound the speaker will emit from the power it’s given. The higher the sensitivity, the more efficient the speaker is with the power it’s given. For lower powered systems, you want a higher sensitivity rating. For a higher powered system, you want a lower sensitivity rating. Lower sensitivity rated speakers are meant to handle higher power.

Frequency Range: Frequency range is the frequencies that the speaker emits sound at, measure in Hz. Normally they are given from a low frequency to high, for example: 20 – 22,000 (22k) Hz. This measure how low and high the speaker can actually emit sound at.

Speaker Design and Materials

Woofer: The speaker woofer can determine the responsiveness, and quality of the speaker. The stiffer and more lightweight the material used, the more effective the speaker is. Polypropylene is a very common material used for the cone, as well as woven fabrics such as kevlar. Aluminum and titanium are also used in higher end speakers.

Woofer Surrounding: The woofer surround also is an important aspect of the speaker system and effect the sound as well. Durable, lightweight, and free moving materials are used to allow the woofer to move with as little energy possible. The material is essential for a long lasting and performing speaker too. As speakers get older and used, humidity levels and wear-and-tear can crack and even break the surrounding of the woofer. Rubber surrounding is typically the most long lasting an high performing material. Foam an cloth surroundings are found on less expensive component speakers, with lower performance and shorter life spans.

Crossovers: When you purchase a component car speaker system, a crossover is almost always a part of the package. External crossovers are typically used to lessen the amount of distortion a speaker might have by separating the frequency inputs. Signals can cross through coated wiring and cause distortion, so an external crossover system will limit this.

At the end of the day, remember that ultimately the best pair of 6 1/2 inch coaxial car speakers will meet the needs of your vehicle, your music preference, and your wallet. In some cases, the products on our list might not be the ideal setup for you so make sure you keep your personal preferences in mind when choosing your next set of speakers

  2. darryl says :Reply

    what type of amp do you suggest if I’m only running a pair of 165 arc focals in the rear

  3. John Binney says :Reply

    Will the the list of coaxial speakers you have listed require an amp when running off a standard 2016 Nissan Qashqai head unit. Infomation is appreciated.

    1. m-segment.ru says :Reply

      We do recommend amplifying all of these after market speakers to bring out their full potential. However, the best coaxial speakers on this list for an OEM head unit would either be the Alpine SPR-60 or Polk Audio DB651
