From what I have encountered, the JL Audio C3 speakers are a winner over their Alpine X-series counterparts. But that is just me, and I think it is important for people to create their own conclusions depending on what strikes them as most compelling.

Keep reading to find out which one is the better option for you. Alpine X-Series vs. JL Audio C3 Series

Alpine X-Series vs. JL Audio C3 Series

Available Sizes

It goes without saying that size is not a factor that will ultimately convince you to purchase something like a set of speakers. Even so, in an effort to do a complete, honest review, size definitely needs to be discussed.

The Alpine X-series comes in only three sizes.

The following is the size range of Alpine X-Series speakers:

The JL Audio C3 series is available in five different sizes ranging from 1” to 6.5”. 

Although the JL Audio C3 has a limited size bracket available, when taking both speaker series into account, they offer a much broader range of sizes for different vehicles.

Build Quality

Alpine’s X-Series speakers have a carbon graphite diaphragm in their tweeters, allowing them to reproduce frequencies up to 55 kHz—a feat typically reserved for aluminum dome tweeters.

Carbon graphite drivers can reproduce high-resolution audio without sacrificing the natural warmth and dampened treble provided by a soft dome’s output.

The speaker cones are made from ultra-thin nanofibers for better sound production. As a result of the nanofiber cone’s excellent internal dampening, any remaining energy swiftly dissipates without altering the sound quality.

What’s more, the stiffness of the carbon graphite in Alpine X-series speakers allows for better precision and extended high-frequency range whilst ensuring the natural sound for a real immersive listening experience and eliminating any harshness in hard dome tweeters.

The JL Audio C3 speakers, on the other hand, are made with durability as a primary design consideration. The injection-molded polymer basket and mineral-filled polypropylene cone that comprise this speaker make it not only long-lasting but also adaptable; they allow it to sustain heavy use without suffering any degradation in sound quality.

The tweeters’ frequency response is fairly broad due to the silk dome diaphragms, and the tweeters’ ability to be flush-mounted or surface-mounted, respectively, makes them suited for a wide variety of environments.

Comparing the build qualities above, both speakers are designed keeping in mind the long-lasting durability, and hence it is evident that none of them have compromised in terms of build.


This is where the difference between speaker series becomes clear as day. But because both the series I’m talking about comprise multiple speakers, it would be difficult to come to a conclusion without comparing their peak potential.

Alpine’s X-Series speakers are designed to work with Hi-Rez systems and deliver a stunning sound when combined with other X-Series components. High-Resolution Audio, or Hi-Rez Audio, is the revolution in digital audio for audiophiles because of its incredible frequency response.

In contrast, the JL Audio C3 speaker series uses a comprehensive arsenal of patents and technological advances to provide unprecedented value, performance, and dependability.

Each speaker comes with a purpose-built, adjustable passive crossover network, an extended woofer excursion capacity with DMA-optimized performance that produces great mid-bass and clean mid-range output, coupled with its strong silk dome tweeter that further pushes high-frequency performance.

Considering the maximum potential delivered by both the speaker brands, The X-S65 (6.5″) from Alpine X-series has a peak power capacity of 330W and a maximum RMS power capacity of 110W.

Its frequency response ranges from 55 Hz to 50 kHz, and its nominal impedance is 4 ohms. These speakers have a sensitivity of 89 dB SPL (1W @ 1m), and it is recommended that they be amplified with up to 100W RMS per channel.

In contrast, the maximum potential that the JL Audio C3 series has is in its C3-600cw speakers. These speakers have a power range (RMS) of 25 to 150 W per channel for their amplifiers and can withstand 75 W of continuous power. The system obtains an efficiency of 89.5 dB when the parameters for the measurement are 1W @ 1m and a nominal impedance of 4.

Thus considering the maximum potential delivering speakers from both brands, both have their highs and lows. I wanted to align my preference on both brands’ peak performance and useful ability, but they seem to have almost similar potential. But the sound clarity is much better in JL Audio C3, which gives it more points in my book.


You can choose from a wide range of prices for both the Alpine X-Series and the JL Audio C3 Series. Pricing for the Alpine X-Series begins at $190 and goes up to $600 for the X-S69C, with the 30 MC being the entry-level option.

On the other hand, JL Audio’s C3 Series has models with price tags ranging from $69 to $600, the lowest-priced of which is the C3-525, followed by the C3-570, C3-570cw, C3-650, and C3-650cw.

If you want more bang for your buck, the JL Audio C3 Series might be the way to go. If your needs and budget do not allow you to buy JL Audio C3 speakers, only then should you go with the Alpine X-series.

The Verdict

Comparing the Alpine X-series to the JL Audio C3-series, I have found that the latter is the better choice due to its exceptional acoustic performance and versatility in terms of size options.

Even though both have the decent build quality, the JL Audio C3 series also stands out in terms of price, making it the more cost-effective option. These factors have led me to favor and recommend the JL Audio C3 series.

Is Alpine Better Than JL Audio in Terms of Speaker Quality?

JL Audio is better than Alpine due to its ability to deliver a smooth and natural sound across a wide range of frequencies. This allows the speakers to produce a powerful and dynamic bass experience.
