【TS-Z1GR｜GRAND RESOLUTION 3-Way Separate Speaker】

When listening to music in your car, you might notice that the vocal position sounds blurred, instrument tones overlap, or that the sound gets a little tiring when you turn the volume up. If you’re looking to improve those concerns thoroughly by replacing your speakers, the TS-Z1GR from GRAND RESOLUTION is a great fit.

This 3-way separate configuration uses a 17cm woofer and a 73mm CST driver, with each unit handling its own range from low to high frequencies. The 73mm CST driver combines a beryllium tweeter and a carbon midrange.

When you actually listen to music, it becomes easier to grasp the vocal positions and the outlines of the instruments, and you can also more readily perceive the depth of the soundstage and its sense of three-dimensionality. It’s not only for enjoying impact at high volume—when playing at lower volumes as well, it naturally conveys even subtle nuances and atmosphere.

The playback frequency range is 29Hz to 90,000Hz. It covers a wide spectrum—from the thickness of low tones to detailed information in the high frequencies. With an “Open & Smooth” design aimed at wide directivity characteristics and low distortion, the speaker is tuned not to emphasize only certain sounds, but to let you hear the entire music with clear perspective.

However, simply replacing the speakers won’t produce the exact same sound in every case. How you hear it can vary significantly depending on the condition of the doors and mounting method, the baffle used, the combination with the factory system, and the adjustments made after installation.

To bring out the TS-Z1GR’s performance properly, installation work and tuning tailored to your vehicle are important. At Log On, we organize the approach together—whether you should replace only the speakers or consider door-side treatments and even the amplifier/DSP—while confirming your vehicle model and factory audio specifications, the music you typically listen to, and your sound preferences.

Just because it’s an expensive speaker doesn’t mean it will fit every vehicle “as is.” If you’re taking the time to choose, it’s worth thinking about what kind of sound you want to aim for after installation. If you’d like to enjoy the music you always listen to a bit more naturally, with more detail, and more comfortably, please consult with us while we look at your vehicle and system condition.
