【CSS674 Rear Separated 2-Way Speaker｜Upgrade Sound Quality from OEM Speakers】

The CSS674 Rear Separated 2-Way is for those who feel that the sound from their factory/OEM speakers is lacking, or for anyone who wants to enjoy music in the car with a bit more power and clarity. It’s an easy choice when considering a swap from OEM speakers, and you can select an installation method to suit your vehicle.

The woofer is designed with an emphasis on low-bass response and sound “cut.” Vocals and instrument sounds are less likely to get buried, so when you listen to your usual music, it’s easier to notice the definition and soundstage. Even when replacing the rear speakers, it can be a chance to help bring the overall sound in the cabin into better balance.

The tweeter uses a titanium material and includes a level switch that lets you adjust the treble in three steps: 0dB, +3dB, and +6dB. This makes it easy to fine-tune to your preference—whether you want to bring the high frequencies out a little more or if the treble feels too prominent inside the cabin.

You can choose from three tweeter mounting styles—flush mount, angle mount, and stand-alone mount—based on your vehicle and installation location. It also features a neodymium magnet and a phase plug for the woofer cone, forming a configuration that supports accurate sound reproduction.

However, the final result isn’t determined by speaker replacement alone. Because installation space, compatibility with the OEM system, and the required modifications and mounting methods can vary by vehicle, the position and orientation you install the speakers at will affect the overall sound impression.

At Log On, we consider together whether the CSS674 will be a good fit while checking your vehicle, your current audio setup, the music you usually listen to, and your sound preferences. If you’re considering stepping up from OEM speakers, don’t decide only on the product—take a look at your actual vehicle and consult us about installation methods and overall balance.
