Choosing Your Sonic Sanctuary: The Infinity Car Speaker Buying Guide
Upgrading your car audio system is exciting. Infinity speakers offer fantastic sound for your drives. This guide helps you pick the perfect set for your vehicle and budget.
Key Features to Look For
When shopping for Infinity speakers, certain features truly make a difference in your listening experience.
Power Handling (RMS vs. Peak)
- RMS Power: This is the continuous power the speaker can handle. Look for higher RMS numbers if you like your music loud and clear. This number shows true speaker strength.
- Peak Power: This is the maximum power the speaker can handle for very short bursts. It’s less important than RMS but still good to know.
Sensitivity Rating
Sensitivity measures how loud a speaker plays with a specific amount of power (measured in dB). A higher number means the speaker gets louder easily, even with a factory radio. Aim for speakers with 90 dB or higher for good efficiency.
Impedance (Ohms)
Most car speakers use a 4-ohm impedance. Make sure your new Infinity speakers match the rating of your car stereo or amplifier. Mismatched impedance can cause problems or lower sound quality.
Speaker Type and Size
Infinity makes several types. Coaxial speakers combine the tweeter and woofer into one unit, making installation easy. Component speakers separate the tweeter and woofer, often giving better sound staging. Always measure your existing speaker openings; standard sizes are 6.5 inches, 5.25 inches, and 6×9 inches.
Important Materials Matter
The materials used in speaker construction directly affect their durability and sound reproduction.
Cone Material
Infinity often uses materials like polypropylene or woven glass fiber for their woofer cones. Polypropylene is tough and handles moisture well, which is great for car doors. Woven materials offer stiffness for clearer mid-bass response.
Tweeter Material
The tweeter handles high notes. Look for soft dome tweeters (like silk) for smooth, non-fatiguing highs. Hard dome tweeters (like aluminum) often produce very crisp, detailed sound.
Surround Material
The surround is the flexible ring holding the cone to the basket. High-quality rubber or foam surrounds allow the cone to move freely, improving bass response and speaker lifespan. Good quality materials last longer.
Factors That Improve or Reduce Quality
Not all Infinity lines are equal. Understanding the differences helps you choose quality.
Factors That Improve Quality
- Three-Way Designs: Speakers with separate woofers, midranges, and tweeters (three-way) generally produce more accurate, detailed sound across the frequency spectrum.
- Strong Magnet Structure: A larger, heavier magnet structure often results in better control over the cone movement, leading to tighter bass and less distortion.
- Crossovers: Component systems include external crossovers. These devices direct the correct frequencies to the correct drivers (tweeter vs. woofer), dramatically improving sound clarity.
Factors That Reduce Quality (Watch Outs)
Avoid speakers that advertise extremely high peak power but have very low RMS power. These speakers often distort quickly when pushed hard. Also, very lightweight baskets (the frame holding the speaker) suggest lower-quality construction that might vibrate excessively.
User Experience and Use Cases
Think about how you use your car stereo.
Daily Commuting and Casual Listening
If you listen to podcasts or light music on your way to work, focus on high-sensitivity coaxial speakers. These are easy to install and sound great even with lower factory power.
Enthusiast Listening and Loud Music
If you crave deep bass and crystal-clear highs at high volumes, invest in Infinity component systems paired with an aftermarket amplifier. The dedicated tweeter placement and external crossovers give you the best sound staging.
Remember: Proper installation is crucial. Even the best speakers sound bad if they are installed incorrectly or if the wiring is poor. Professional installation is sometimes recommended.
Infinity Car Speakers: Top 10 FAQs
Q: Are Infinity speakers easy to install myself?
A: Coaxial speakers are generally very easy to install, often fitting right into factory locations. Component systems require running a new wire to the separate tweeter, which takes a bit more effort.
Q: Do I need an amplifier for Infinity speakers?
A: You don’t *need* one, but an amplifier will significantly improve their performance, especially for higher-end Infinity models. Amplifiers provide clean, dedicated power.
Q: What does “Infinity Kappa” mean?
A: Kappa is usually Infinity’s high-end line. These speakers use premium materials and offer superior sound quality compared to entry-level or mid-range options.
Q: Can I mix and match different Infinity series speakers?
A: While technically possible, it is best practice to keep speakers on the same circuit (e.g., all Kappa or all Reference) for a balanced sound profile throughout the car.
Q: How do I know what size speaker fits my car?
A: You should always check an online vehicle fitment guide provided by Infinity or a retailer before purchasing. Standard door sizes are 6.5 inches or 5.25 inches.
Q: Will these speakers work with my existing head unit (stereo)?
A: Yes, most Infinity speakers are designed to run off standard aftermarket or factory head units, though performance improves with more power.
Q: What is the difference between a woofer and a tweeter?
A: The woofer handles the low and middle sounds (bass and vocals). The tweeter handles the very high sounds (cymbals and airy details).
Q: How long do Infinity speakers usually last?
A: With proper power handling and protection from extreme moisture, quality Infinity speakers often last 5 to 10 years or more.
Q: Do Infinity speakers handle extreme weather well?
A: Many modern Infinity cones (like polypropylene) are built to resist temperature swings and humidity found inside cars, which increases their lifespan.
Q: What frequency response is considered good?
A: A wider frequency response range (e.g., 35Hz to 25,000Hz) means the speaker can reproduce a broader spectrum of musical notes, leading to richer sound.
