【Pioneer Carrozzeria TS-C1746S｜17cm Separate 2-Way That Naturally Improves Sound Quality from Factory Speakers】

If the sound from your factory speakers is,

• Vocals sound muffled
• It feels like the sound is gathered at your feet
• Instrument sounds overlap, making fine details hard to distinguish
• You want to enjoy music more comfortably

Then Pioneer Carrozzeria TS-C1746S is an easy speaker to consider.

This is a 17cm separate 2-way type, combining a door-side woofer with a tweeter responsible for the high-frequency range. By replacing your factory speakers, the vocals and instrument sounds are more likely to come together toward the front, making the music you normally listen to feel more three-dimensional.

Vocals and instrument positions are naturally easier to “pull forward”

The appeal of the TS-C1746S is not simply that the sound gets louder.

By installing the tweeters characteristic of a separate 2-way system properly, the mid-to-high frequencies—such as vocal clarity, guitar, piano, and more—become easier to hear, helping to change the impression that sound is coming from only near your feet.

It’s the kind of model where you can feel the difference in everyday listening: J-POP and radio during your commute, streaming audio, music on long drives, and more. Even if you don’t chase perfectly detailed tuning, I think it’s also attractive that you can still settle into Carrozzeria-style, naturally listenable sound with a wider sense of spread.

For those who want to start with speakers first, while keeping the factory navigation

“I want to keep using the navigation and factory audio as-is”

“I’m not thinking about making major system changes”

“Since my family rides with me too, I want natural sound that isn’t flashy”

In cases like these as well, the TS-C1746S is a compatible choice.

Replacing speakers is one of the easier starting menus in car audio, but the required mounting parts and any processing will vary by vehicle model. It’s important to move forward with a plan for how much you want to improve the sound while preserving, as much as possible, the factory usability and the appearance of the interior.

Even with the same speaker, the sound impression changes depending on how it’s installed

Speakers don’t produce the same sound just because you install them.

The way the sound comes together depends on factors such as the door-side structure, the condition of the mounting surface, the fixing method, the tweeter position, and how it’s combined with the factory navigation or head unit. If the mounting surface isn’t solid, the speaker’s movement may not translate into sound effectively.

At Logon, we organize the necessary installation approach while confirming each vehicle’s door structure and interior conditions. Depending on the situation, we consider together the parts worth investing in—including mounting components such as baffles and door-side processing.

After installation, we check how the left and right channels connect, the vocal positioning, and the balance between high and low frequencies, then adjust it to suit the vehicle and your usual listening style. If it were me, I wouldn’t decide based only on the speaker unit itself—I’d choose including how it will be mounted in the car and how far the finish should go.

You can start by consulting about “how much work will likely satisfy you”

The TS-C1746S is a model that makes it easier to balance change and ease of handling for people considering an upgrade in sound quality from factory settings.

However, depending on your vehicle model and the specifications of the factory audio, the suitable installation method and required work will differ. There may also be vehicle-specific conditions, so rather than deciding only the product first, it’s better to confirm the actual car and your current system before proceeding—so it’s less likely that the discussion will change later.

Even if you want to improve the sound but don’t want to overdo it, you can organize a realistic plan by hearing what music you usually listen to and your budget.

If you want to enjoy the vocals and instrument sounds a little more comfortably in your usual car cabin, give the TS-C1746S a spot on your shortlist. Let’s work together to finish it into great sound, including an installation method that suits your car.
