【CSS654｜2-Way Component Speakers That Lift Your Car’s Sound Naturally】

You may feel that the sound of your factory speakers is lacking, but instead of boosting only the bass, you want to hear the subtle details in vocals and instruments clearly. If that’s what you’re looking for, you should consider CSS654.

These speakers are a 2-way component type installed separately with a woofer and a tweeter. By combining a woofer that handles the mid and low frequencies with a titanium tweeter that expresses sound contours and airiness, vocals and instrumental details that are often hard to pick out with factory speakers can be experienced more naturally.

For the tweeter, there are three pod options: flush, angle, and surface-mount. Because you can choose the installation method based on your vehicle model, the shape of the dashboard, and how you want the sound to spread, the installation is not just about producing sound—it’s important to have the setup consider how well the music comes together and how it sounds from the driver’s seat.

The system also includes a switch that lets you adjust the tweeter level in three steps, making it easier to fine-tune whether the highs feel too strong or you want a bit more presence in the sound. The compact 12dB crossover is another practical point designed with installation inside the cabin in mind.

While the CSS654 is designed to fit many vehicles, the actual finish will vary depending on the vehicle model, the specifications of the factory audio, the condition of the doors, and the installation method. Satisfaction after installation will also depend on details beyond simply swapping the speakers—such as how the mounting base is made, how the door is treated, the tweeter orientation, and how well it matches the factory system.

At LOGON, we discuss whether the CSS654 will suit you together, including your preferred music and sound characteristics. Rather than deciding the product first, tell us which parts of your current sound you’re not satisfied with and what kind of sound you want. If I were helping you, I would confirm your vehicle model and factory system first, and then guide you with the right combination of installation and required work.
