Basically, we do not finish by using measurement instruments continuously for standard sound tuning.
We mainly use measurement tools when the customer requests it, or in situations where numerical verification is required—such as for contests or competitions.

There are many aspects of in-car sound that cannot be fully judged by frequency numbers alone.
The balance that actually sounds enjoyable can change depending on factors such as the glass, interior panels, seat position, speaker mounting conditions, the volume you typically listen at, and the genre of music.

At LOGON, we adjust while actually listening to music—checking and tuning things like the vocal placement, how smoothly the bass connects, how sharp the high frequencies feel, and whether you can listen for a long time without getting tired.
Rather than focusing solely on getting the numbers right, we prioritize making it possible to enjoy music naturally in that car.

Of course, we can also accommodate cases where confirmation using measurement tools is necessary, or if you have specific requests.
For DSP tuning and system-upgrade setup, we proceed while looking at the car’s condition and how the customer listens, and incorporate measurements as needed.
