In most cases, the speakers that come in factory stereos don't meet consumers' expectations for quality, longevity and most importantly performance. Finding an all-around Best 5.25in Car Speaker that will significantly boost your stereo's performance while maintaining a high expectation for quality, dollar value and most importantly sound reproduction, can be difficult and time consuming. A good pair of speakers will allow you to turn up the volume while lowering distortion and bring true sound to your music. If you're unsure whether your car will fit a 5 1/4″ speaker, check out our car speaker fitment guide to confirm the speaker sizes for your year, make and model.

Also referred to as “separates”, component speakers have two separate speakers that emit different ranges of frequencies and sounds. The woofer, or the larger speaker, emits the lower to mid range frequencies while the tweeter, the small speaker, covers the very high range frequencies and noises. Separating the tweeter and woofer allows for clearer sound with less distortion. Pair them up with one of the Best Car Stereos on the market, and you'll find yourself reluctant to leave your car when a good tune is playing.

Focal PS 130F Quick Review

The Focal PS 130F brings the benefits of Focal’s incredible flax cone technology to these 5.25” speakers so you can enjoy all that its 6.5” counterpart (the Focal PS 165FX) has to offer – but now in a smaller package. The French engineers at Focal have used the same technology and materials to manufacture this unit as with the PS 165FX. It uses the innovative lightweight flax cone made of hollow fibers starched in between thin glass membranes to produce rich, natural, and accurate sound. The flax cones are well known for their ability to deliver smooth, precise sound with incredible mid-range frequencies and good bass.

The speakers combine this innovative Flax technology with Focal’s renowned inverted dome tweeters to produce the best sound performance that a 5.25” speaker can possibly give. The tweeters are supported with a Poron suspension for long life. They work like a small woofer by dispersing high frequencies over a broad area and hence making it possible to generate crisp-clear sound without distortions.

The speaker system also comes with 2-way external crossovers to help you make the right adjustments to your woofers and tweeters for the perfect balancing of all frequencies. Just get an amp (the speakers can handle up to 120 watts) and give an extra punch to these speakers!

  • Produces natural, rich and accurate surround
  • Has high sensitivity
  • Great technology offers enhanced performance
  • Well-built for guaranteed durability
  • Good aesthetics

Best Car Speakers: Common Speaker Terms & Ratings

When comparing and choosing the Best 5.25″ Component Car Speakers on today's market, CarAudioNow 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.
