【KICKER KSC504 10cm Coaxial Speakers】

The sound from the factory speakers just isn’t satisfying.
But you don’t want to make major modifications.
That’s exactly where the Kicker KSC504 fits.

Even in the 10cm class—still relatively small in diameter—you’ll notice a real difference in the amount of audio information and overall listenability.
With the lively energy you expect from KICKER, the KS series is also designed to be less harsh on the ears, making vocal and instrument contours easier to hear. Even on short commutes or quick trips to the store, you can pick up the difference easily, and it’s a model that’s easy to dial in toward reduced fatigue over long listening sessions.

Thanks to a polypropylene woofer with internal vibration damping combined with a rubber surround, it reproduces clearly from the midrange down to the foundation of the bass.
For the high frequencies, the silk dome tweeter extends naturally.
This is what makes the KSC504 appealing: it’s easier to keep common complaints with factory speakers in check—such as muffled sound, vocals seeming to retreat, or the sound becoming unpleasantly loud when you turn up the volume.

Another major point: this model also uses a slim, low-profile design.
With a shallow mounting depth and the tweeter protruding by only a small amount, it’s the kind of speaker that’s easier to choose even for vehicles with limited space. When considering installation in the factory location, this “ease of fit” is actually quite important. Speaker quality isn’t only about performance—how cleanly and without strain you can install it directly affects the final result and your satisfaction.

At Logon, we don’t stop at simply replacing the speakers.
We carefully handle everything—from the installation method to wiring and how to secure the speakers—while checking the door structure of each vehicle and how well it matches the factory head unit.
Even with the same speaker, the way the sound comes together can change depending on mounting stability and small gap treatments, and how it sounds can change significantly with adjustments tailored to your way of listening.
Avoiding the “It’s installed, but it didn’t change as much as I expected” outcome is a major advantage of entrusting the work to a specialty shop.

The KICKER KSC504 is
・For those who want to feel a clear improvement over the factory speakers
・For those who want a model that doesn’t make the highs too harsh
・For those who are concerned about installation space
・For those who want to start with a replacement first
—and is a highly realistic and easy-to-pick option.

Because finishing can vary depending on whether mounting parts or light machining are required for each vehicle, it’s best to evaluate each specific car.
With Logon, based on your vehicle and your current system, we can guide you including a no-nonsense installation approach and how to achieve cohesive sound.
It’s also a model that makes it easier to move forward while consulting us, even for first-time speaker replacements.

If you’re looking for changes like these

• You feel the factory sound is thin or muffled
• You want vocals to be easier to hear
• You want to enjoy music comfortably even at low volume
• You want it to look natural installed in the factory locations on the door or dash
• You want an exchange that delivers satisfaction without spending too much first

Points where installation and tuning make a difference

The KSC504 is easy to introduce due to its size, but it’s also a speaker whose impression can change depending on the condition of the mounting surface and how gaps around it are treated.
That’s why it’s important not just to swap it in, but to fit it properly according to the vehicle’s conditions.

At Logon, we finish the job with an emphasis on achieving a state you can use safely and comfortably for a long time, including treatments for parts you can’t see and how to bundle wiring.
If needed, we can also discuss deadening and system upgrades, but we won’t unnecessarily expand the conversation—our proposals will be based first on how to best make use of this speaker.

Summary

The KICKER KSC504 is a well-balanced 10cm speaker suited for people who want to clearly hear the difference when replacing the factory speakers.
Not flashy—but it makes a real change.
That “just right” balance is the strength of this model.

If you look at it including the installation conditions for your vehicle and how well it matches your current audio, you can choose with fewer regrets.
Even if you’re at the stage of thinking, “I want to consult whether it will suit my car,” that’s fine.
With Logon, we’ll guide you with an eye toward making sure you’re truly satisfied after installation.
