Custom-fit speaker TS-C1740S Rear separate 2-way

Even the expressions of familiar songs come through vividly.

【Custom-Fit Speaker TS-C1740S Rear-Separate 2-Way】

You want a bit more clarity and spaciousness from your factory speakers. You want to feel the vocals closer. You want to enjoy the music you always listen to even more comfortably inside your car.

If that sounds like you, consider the Custom-Fit Speaker TS-C1740S Rear-Separate 2-Way.

With a separate configuration combining a 17cm woofer and tweeter, each speaker handles its own frequency range. This makes it easier to see fine details in vocals and instruments, and gives the sound contours a more organized impression. Because you can also more easily perceive the music’s spread from the rear side, it’s well-suited for those who often have passengers in the back seat.

The woofer uses a two-layer aramid fiber cone and a corrugated edge. It’s designed for people who want to enjoy the bass in a balanced way—not just emphasizing the amount of low end, but also the movement of the bass line and the way sound comes in.

The tweeter is a φ29mm balanced dome tweeter. While extracting plenty of high-frequency information, it reproduces vocal and cymbal sounds in a way that’s easy to hear. You’ll also find it easier to sense the soundstage spread and lingering reverberation, and even your usual songs may offer new discoveries.

However, simply replacing speakers won’t determine the result by itself. The final outcome will vary depending on factors such as the installation condition on the door side, the mounting base that fixes the speakers, compatibility with the factory audio system, and the front-to-rear volume balance.

At LOGON, after confirming your vehicle model, your factory system, and how you usually listen to music, we help you sort through whether it’s best to replace only the rear speakers or whether you should also consider the front side.

If it were me, I wouldn’t decide on the product first only. I would ask about your current sound concerns and your budget, and then choose everything—including the installation approach. Even with the same speakers, the satisfaction you feel after the change will differ depending on where and how they’re installed.

We can help from consultations like “I want a bit better sound than the factory setup” to “I want to thoroughly tune the entire cabin.” First, tell us which parts of your current sound you’re concerned about. Let’s think together about a reasonable sound setup that fits your car.
