【RS X165｜3Ω・165mm 2-Way Speaker】

If you feel slightly unsatisfied with the sound of the factory speakers, or if you want to hear vocal voices a bit closer and more clearly, you should consider the RS X165.

With a 2-way setup combining a 165mm mid-woofer and a 28mm high-performance tweeter, it reproduces everything from the mid-bass and mid-low frequencies that form the foundation of music to the fine details in vocals and instruments—balanced and well integrated. Even with the songs you already listen to, changes in sound thickness and the clarity of each part can make your time listening to music in the car far more enjoyable.

The mid-woofer uses a diaphragm made with an XP-coated SBC-412 paper cone. Designed with a focus on balancing light weight and strength, it is a speaker that emphasizes fast sound onset and detailed reproduction of the mid-low range.

One of this speaker’s features is the 9-setting crossover. Because it offers flexibility to adjust according to your car’s acoustic environment and your preferences, it’s not something you simply install and finish—you can fine-tune it while taking the balance with the entire vehicle into account.

Even with the same RS X165, the overall impression of the final sound can vary depending on the door-side base construction, how the speakers are mounted, wiring treatment, and how the tweeters are installed. If it were me, I wouldn’t decide solely by swapping the speaker unit by itself; I would also check the factory system and how you use the car, and make adjustments where needed.

Whether you want to “increase only the bass,” “make vocals easier to listen to,” or “achieve a sound that’s less fatiguing even after long sessions”—the ideal configuration depends on your goal. Let’s review together how best to incorporate the RS X165 while confirming your vehicle model and your current system.
