JBL and Infinity speakers are both huge contenders in the audio system industry. Not only do they originate from the same parent company, Harman International Industries, but they also produce a wide selection of high-quality speakers for a variety of audio applications. So, let us discover the features and differences between Infinity car speakers and JBL.

When I first got my car, I must say I was not pleased with its factory-installed system. Personally, I enjoy cranking up my music while I drive around doing my errands. As such, the audio system in this car was horrible. Once I cranked up its volume, the bass output was too deep, and the high frequencies were too screechy. Consequently, I decided to change the car’s sound system.

Your vehicle’s audio experience is mainly dependent on the quality of car speakers. Unless you own a top brand car model with a premium quality pre-installed sound system, it is highly likely that you have thought about customizing or upgrading your vehicle’s audio system as well. Unfortunately, changing your vehicle’s factory speakers is more pocket-friendly instead of replacing the car’s sound system as a whole.

Due to the numerous options available in the market, finding the right pair of speakers for my vehicle was more complicated than removing its factory-installed speakers and replacing them with new aftermarket ones. I had to completely understand how the car’s audio system functions before dashing to my local sound equipment store to purchase a set of new car speakers. After a while of thorough research, Infinity and JBL car speakers were among the top contenders on my list. Without further ado, let us find out which brand has better car speakers in this Infinity car speaker vs. JBL review.

Infinity car speakers vs. JBL – How do they compare to one another?

Tweeter design and composition

The design and material composition of a tweeter affect the quality of the sound of your audio system. Infinity car speakers feature 1″ edge-driven and soft textile dome tweeters that create a more extensive, smoother, and clearer sound dispersion with minimal distortion at high volumes. Its tweeters also contain a UniPivot tweeter design that allows the listener to position them in any position, ideal for stereo imaging even when your speakers are installed way down low in your doors. Each tweeter comes with adjustable level control, which allows you to control the brightness to your preference.

On the other hand, JBL car speakers come with two one-inch edge-driven, soft-dome silk tweeters, which are perfect for decreasing high-frequency distortion and boost power handling. The edge-driven tweeters allow lower crossover frequency and enhanced sound distribution features, ideal for imaging and delivering excellent sound quality. These speakers also have a UniPivot tweeter design with adjustable dual level control that allows brightness control from zero to three decibels, which accounts for road noise or off-axis and low mounting position of the speakers.

Woofer composition and design

Woofers aid in the delivery of the low bass output of your music in your vehicle. Infinity car speakers come with two Patented Plus One Woofers made from formed glass-fiber to ensure the device holds its shape when cranked up, while still delivering defined and punchy bass sound. The glass-0fiber material of the woofer is lightweight and stiff, ensuring it provides excellent response and is resistant to environmental extremes like moisture, cold, and heat. Its woofers have hi-roll butyl rubber surround, ascertaining its durability and longevity while in use.

Alternatively, JBL car speakers have Patented Plus One carbon-injected woofer cones that provide more speaker-cone surface area. As such, the cones are stiffer and lighter to allow the speaker to radiate more air and produce a low-frequency response and less power to create more defined and clearer audio notes.

Frequency sensitivity

The frequency sensitivity of a speaker measures the amount of sound the speaker produces when you apply a certain amount of wattage to it. Infinity car speakers have a varied range of frequency sensitivity, depending on the type of speakers used. The Infinity Kappa 62.11i series has a frequency sensitivity rate of 95dB at 2.83 volts, and an impedance of 2-ohms, meaning they are strong enough to hook up to factory-installed stereo systems.

Similarly, the sensitivity of JBL speakers also varies with the type of speakers you purchase. JBL GTO629 car speakers have a frequency sensitivity of 93dB at 2.83 volts, and an impedance of 3-ohms. With their low impedance three-ohms voice coils, you can compensate for your less-than-perfect speaker location to suit your personal musical taste and listening preference.

Frequency response

Frequency response refers to the range of audible frequencies a specific speaker can produce. Generally, human hearing cannot extend to 20000 Hz or bass frequencies below 30 Hz. Different speaker series have different frequency response ratings. For instance, the Infinity Kappa 62.11i series car speakers have a wide frequency response range of 45 Hz – 25000 Hz, while JBL GT0629 speakers contain a frequency response of 53 Hz – 21000 Hz. From the frequency response ratings of the two speakers, JBL car speakers deliver louder and clearer full-range sound quality with minimal high-frequency distortion.

Power handling

Power handling aids in knowing the amount of wattage a speaker can tolerate at a short burst and continuously. Power handling measurements depend on your car system, in that low-powered car systems do not require high-powered speakers. On the other hand, car systems with external power sources or amplifiers require speakers whose power handling ability is close to the power output rate of the amps.

Infinity car speakers have varied power handling capabilities depending on the type of speaker purchased. For instance, Infinity Kappa series 62.11i car speakers have a power handling of 5-75 watts RMS and 225 watts Peak Power. On the other hand, JBL GTO629 car speakers deliver sharp and clear sound waves from an amplifier or external head unit capable of producing 5-60 watts RMS with 180 watts Peak Power. As such, Infinity Kappa 62.11i speakers are more reliable in terms of power handling over the lifetime of the speaker.
