【Carrozzeria TS-C1740S｜Upgrade from the OEM speakers to enjoy vocals and a wider soundstage with a 17cm separate 2-way】

While listening to music in your car, have you ever felt that “the vocals are a bit far away,” “the sound is bunched up near your feet,” or “the OEM speakers aren’t good enough”?

Carrozzeria TS-C1740S is a 17cm separate 2-way speaker that’s easy to consider if you’re looking to improve sound quality over your OEM speakers.

The design supports the mid-bass and lower frequencies firmly with the door-side woofer, while reproducing the high frequencies with a separate tweeter. This makes the outlines of the sound easier to hear and helps you naturally perceive the positions of vocals and instruments.

Vocals are easier to make out, and the whole music is more organized

The change you’ll hear after switching to the TS-C1740S isn’t simply that the sound gets louder.

• Vocal placement comes forward
• Lyrics and radio voices become easier to understand
• Bass and kick drum outlines become clearer
• The sound spreads toward the front rather than staying only near your feet
• Even at lower volumes, you can feel the music comes together

This is the kind of model where the difference from OEM speakers is easy to notice—not only with commuter radio and music streaming, or the J-POP and vocal tracks you usually listen to, but also with live recordings, rock, and more.

When you listen to your usual songs again, sounds you hadn’t noticed before start to come through naturally. This is for people who want to enjoy that kind of change.

Separate 2-way sound—how it “shows up”

The TS-C1740S uses a separate configuration where the woofer and tweeter are divided.

On the door side it reproduces mid and low frequencies, and by adding the high frequencies from the tweeter, it helps prevent the sound from becoming too concentrated near your feet—making the overall music easier to listen to from the front.

The key point is that it’s not about emphasizing only the treble. Instead, it’s designed so the connection from bass to treble is included, resulting in a sound that’s easy to live with day to day.

It’s also a speaker that you can easily consider if you want to reduce the “muffled” feel of OEM sound but don’t want it to be flashy.

Speaker sound quality changes with installation method

Even with the same product, the impression you get can vary depending on the vehicle and the installation method.

What you’ll need to check differs from car to car, such as the condition of the door and available mounting space, how it pairs with your OEM navigation and head unit, the tweeter orientation, and how well the trim fits.

Especially to make the speakers perform properly, it’s also important to prepare the mounting base and process the door side. If installation isn’t correct, you may not be able to fully use the speaker’s original performance, and you might hear rattles or unwanted resonance.

At LOGON, we don’t stop at installing the product. While confirming the vehicle condition and the customer’s preferences, we plan a reasonable installation approach.

If I were choosing, I’d rather organize these points together before deciding than pick the speaker first.

• Compatibility with the OEM navigation or head unit
• Condition of the door side
• Whether deadening and mounting parts are needed
• Which part of the sound you want to change the most
• Whether you plan to expand the system in the future

Doing it this way makes it less likely that, after installation, you’ll hear “the sound is different from what I expected.”

For your first sound-quality upgrade, too

If it’s your first time replacing speakers, you may have concerns like “Can it be driven by the OEM navigation?”, “Will the sound become too harsh?”, or “Will the interior be strained?”

The TS-C1740S is a model that’s easy to consider as an upgrade from OEM speakers, but actual fitment, required parts, and installation methods vary by vehicle.

Even though there are parts you can confirm in advance if you know the vehicle model, year, and OEM audio specifications, for accurate consideration up to the installation method and finish, consultation while viewing the actual car is the surest way.

You may want to improve your sound, but not know where to start. In that case, it’s still okay. While listening to the music you usually enjoy and your current complaints, we’ll think together about whether the TS-C1740S is a good match—or whether another approach would be better.

Summary

Carrozzeria TS-C1740S is a 17cm separate 2-way speaker designed for people who want to reduce the “muffled” feeling and lack of satisfaction of OEM speakers, and enjoy clearer vocals and a wider soundstage.

A speaker replacement changes the impression of the finished result not only by choosing the product, but by considering installation and sound tuning tailored to your specific vehicle.
