【165 S300 A Separate 3-Way Speakers｜For Those Who Want to Enjoy High-Detail Sound】

Replace the factory speakers and want to hear vocals and instruments a little more clearly. Even when you turn the volume up, you want the sound to stay full and powerful—without getting thin.

That’s exactly what the 165 S300 A Separate 3-Way Speakers are for.

In a 3-way setup where the woofer, midrange, and tweeter are each independently driven, the system shares the workload from low to high frequencies for playback. Because it’s easier to increase the amount of sonic information, you can expect a change that makes you want to listen to your usual tracks again—down to the position of the vocals and the subtle expressions of each instrument.

The 6.5-inch woofer uses a carbon-fiber cone and a large-capacity magnetic motor. This is a configuration for people who want not just loud bass, but solid reproduction as a foundation that supports the entire music.

For the midrange, the S 3.55 with an aluminum phase plug is used to handle the frequency band that forms the core of music—vocals, guitar, piano, and more. The high frequencies are handled by the T20HR 20mm textile-dome tweeter, aiming to make even fine details easy to hear naturally.

However, a 3-way speaker system isn’t something that’s finished simply by installing the product. The final impression will vary depending on factors such as the installation strength of the woofer, processing on the door side, the positioning of the midrange and tweeter, and how it’s matched with the factory audio.

If it were me, I wouldn’t decide based solely on replacing the speakers by themselves. I’d check your current system and how you use the car interior before planning the configuration. Where needed, I’d also want to arrange the installation—including door-side work and installation methods—so that the 3-way setup can be utilized comfortably and effectively.

If you want to enjoy music properly, feel that the factory speakers don’t quite satisfy you, or want to enhance the soundstage and the presence of the vocals, please consult us while confirming whether it suits your vehicle model and your current system. Together, we’ll consider a setup that fits your car—and that you’ll be glad you chose after using it: “I’m really glad I went with this combination.”
