Signature Series—16.5cm 3-Way that captures the passion of music.
[Includes 165 S300 Passive] 3-Way Car Audio Speakers
These are 3-way separate speakers designed for those who have started to feel that the factory speakers aren’t enough, and for those who want to enjoy not only the presence of vocals, but also the fine details in instrument sound.
165 S300 (with passive) is a set that combines a 6.5-inch woofer, midrange, and tweeter. Since each unit handles a specific range from low to high frequencies, it’s easier to keep the sound overlap organized, creating a system where you can perceive the vocal position and instrument timbre in greater detail.
Bass isn’t just about producing more quantity—it serves as the foundation that supports the entire piece of music. The midrange presents the character of vocals, guitars, pianos, and more in a natural way, while the treble is handled by a textile dome tweeter that delivers detailed information in the high frequencies. This configuration is designed to help you notice sounds in familiar songs that may have been buried until now.
The midrange uses an aluminum phase plug, and the woofer uses a carbon-fiber cone. Although the design is capable of handling high input levels, to bring out the best in these speakers, it’s important where the units are mounted, the door-side treatment, and how the woofer, midrange, and tweeter are connected.
Because a 3-way system uses more units, the final impression can vary more easily depending on how it’s installed and adjusted. At Logon, we’ll organize the necessary installation details together while confirming your vehicle model, the specifications of your factory audio, the music you want to listen to, your usual listening volume, and your preferences.
If it were me, I wouldn’t stop at just replacing the speakers. I’d consider a form you can enjoy comfortably for a long time, including the installation method, the condition of the doors, and—if needed—the combination with an amplifier and DSP. It’s not simply about choosing an expensive system; selecting a setup that fits how you use the car and your budget is the point that helps you avoid regrets later.
If you want to increase the thickness and information content of the sound, or if you want to build a strong front soundstage, please feel free to consult us about how much you can change things with your own car. Because the suitable installation approach can differ depending on the vehicle model and the factory system, we recommend deciding the direction while confirming the actual vehicle.
