【RS 1.0 Tweeter｜A Speaker for Enjoying Natural High Frequencies and Fine Detail】

The RS 1.0 Tweeter is designed for those who want to hear vocals breathe and subtle instrument nuances a bit more naturally—and more carefully.

Its strength lies not in simply boosting high frequencies, but in smoothly drawing the sound’s contours and lingering resonance. Instead of vocals sounding too forward or cymbals feeling too prominent, you’ll find it easier to calmly perceive the small details that are already hidden in the music you listen to every day. It’s a tweeter we recommend especially for anyone who wants to enjoy music on long drives.

The ultra-lightweight soft-dome diaphragm suppresses unnecessary resonance and contributes to natural high-frequency reproduction. With a neodymium magnet and back-magnet structure, a copper top cap, a cast aluminum rear chamber, and dedicated cooling design, it achieves both delicacy and stable drive.

Tweeter sound quality changes not only with the product itself, but also with where and how it is installed. It’s important to adjust not just the pitch and soundstage, but also the vocal position—while checking how it connects with the factory speakers and your existing car audio system.

The RS 1.0 Tweeter features a detachable mount ring, making it easier to consider everything from replacement that matches the factory size to custom installations. Since the best installation method varies by vehicle and system, I would check the actual car and your current sound first, then think together with you about whether to proceed with the tweeters alone or to integrate them by aligning the door speakers and a DSP.

If you’re slightly dissatisfied with how the high frequencies come through, if you want vocals to sound a little more natural, or if you want to change the impression of the sound by replacing speakers, please let us know your vehicle model and current system. We won’t force you to decide on the product alone—we’ll guide you by considering a setup that you can enjoy comfortably after installation.
