【carrozzeria TS-Z900PRS | High-Quality 3-Way Speaker with TAD’s CST Driver】

If you want to replace your factory speakers and enjoy the music more naturally—down to the vocal placement and the subtle nuances of instruments—then the model to consider is carrozzeria TS-Z900PRS.

Using a CST driver that inherits TAD’s technology, the midrange and tweeter are mounted coaxially. With a design that makes it easier to align the sound arrival times from the two units, this 3-way speaker stands out for how easily you can achieve a well-connected sound.

The vocal at the center of the sound is less likely to blur, and the mid-to-high frequencies—such as guitar and piano—become easier to follow note by note. Sound spreads naturally forward, so even with songs you’ve always listened to, you can aim for an output that helps you notice details and the atmosphere of recordings that you may have missed before.

The woofer features a 17cm two-layer cross-carbon diaphragm. Rather than simply increasing the amount of bass, it brings out a thick, door-speaker-style sound while also taking the connection with the midrange into account. Because it is built to be water-resistant, the design is also considerate of the environment inside the door.

However, speaker performance isn’t determined by simply installing the product. Depending on the door’s mounting base, vibration control, how you choose the baffle, the installation method, and the combination with an amplifier and DSP, the impression you get can vary even with the same TS-Z900PRS.

At LOGON, we confirm your vehicle model and factory system, the music you typically listen to, and your sound preferences—then we think together about how much work needs to be done to achieve higher satisfaction. Since these are high-performance speakers, it’s important not to add everything just because you can, but to finish it in a form you can enjoy comfortably for a long time through installation and tuning that suit your vehicle.

If you feel like you want “to make the factory sound a bit clearer,” “to hear vocals more naturally,” or “you’re interested in a 3-way setup but tuning seems difficult,” please consult us while checking your vehicle specifications and how you use it. If I were doing it, I would start by looking at your current system, then organize a configuration that makes the best use of the TS-Z900PRS.
