Yes, we can improve it quite a lot.

If the high frequencies are sharp and cause listening fatigue, it’s often not that the speaker itself is bad, but that the installation condition, sound adjustments, and the in-car environment have a big impact.
So rather than simply swapping parts, by tuning things while checking where the sound is coming through too strongly, you can reduce the “piercing” sensation and move closer to a more comfortable sound.

At LOGON, we get consultations like this quite often.
In practice, we look at points such as the following in order.

• Whether the output of the high frequencies is too strong
• Whether there’s any mismatch in the speaker orientation or installation method
• Whether the sound balance adjustment is set correctly
• Whether reflections around the door are making the high frequencies harsher

In particular, after replacing with aftermarket speakers, or after changing the settings on the navigation unit, DSP, or amplifier, there are many cases where people are concerned that the sound is thin and hard, the “sa-gyo” (s sounds) stand out sharply, or it becomes painful when you turn up the volume.
In some cases, reviewing the settings alone may solve it, while in other cases, it may come together more naturally when you also adjust the installation and include surrounding installation work.

What’s important is that you shouldn’t simply lower only the high frequencies “by force.”
If you lower them too much, the sound can become muffled; therefore, at LOGON we focus on maintaining a balance where the vocals and instruments sound properly while keeping the harshness down.

If you feel something is off with your current sound,

• what kind of sound bothers you
• when it bothers you
• whether you’ve already replaced or adjusted the speakers

Having this information will make it much easier to judge.

We receive many inquiries like “The high frequencies are too strong and it’s exhausting, but I don’t want it to sound muffled either.”
Depending on your vehicle model and current system, we can suggest realistic improvement methods, so if you’re concerned, it’s totally fine to start with a consultation.
