【ETON CSR-16 Rear Separated 2-Way｜A Sound with a Core that Naturally Spreads to the Rear of the Cabin】

If you’re looking to improve the overall cohesiveness of sound throughout the car by replacing the rear speakers, we recommend the ETON CSR-16 Rear Separated 2-Way.

Even if you replace only the front speakers, the sound from the rear may feel lacking when you often listen to music from the back seats, or when you want to enjoy a natural soundstage across the entire cabin. The CSR-16 is designed to incorporate a separated configuration on the rear side as well, extracting a solid amount of sonic detail and clarity even from the back.

Fine Detail and a Solid Mid-Low Range

The tweeters use a 25mm ceramic-coated aluminum dome. They reproduce high-frequency information—such as subtle vocal expressions and the lingering resonance of instruments—naturally and clearly.

The mid-bass features a 160mm CRG fiber cone. Not only does it deliver a lively start, it also has a strong core in the mid-low range that serves as the foundation of music. This configuration makes it easy to enjoy a wide variety of music—from delicate acoustic tones to powerful rhythms in rock and pop.

When you replace the rear speakers, not only does the sound you hear in the back seat become easier to listen to, but the overall sound in the cabin is less likely to feel thin, and the transition with the front side becomes easier to balance.

A Passive Network That Lets You Dial in the Sound to Your Preference

The CSR-16 also supports sound-quality tuning via a passive network. Since the tweeter level can be selected from -3dB / 0dB / +3dB, you can adjust it to match how the cabin sounds and your personal preferences.

It’s appealing that you can fine-tune while checking the sound after installation—whether you want to bring the high frequencies slightly forward for a brighter sound, or shift it toward a more relaxed balance.

Speaker Sound Changes with Installation Method

Even with the same speaker, the final result varies depending on the installation space for each vehicle model, the structure of the OEM speakers, and the condition of the mounting surface. Especially on the rear side, it’s important to check details such as the speaker depth, the tweeter’s placement, and how it relates to the OEM grille.

Because the mid-bass mounting depth is 66.4mm and the tweeter’s is 15mm, confirming the available space in your actual car is essential. If needed, proceed while considering an installation method suited to your vehicle and combinations with surrounding parts.

If it were me, I wouldn’t choose the speakers first and only. I would confirm the current front setup, the OEM system, the music you typically listen to, and whether you prioritize the front seats or the rear seats. The best combination changes depending on whether you want the rear to sound firmly or you want the entire cabin to feel naturally tuned.

We can work out together whether the ETON CSR-16 will suit your vehicle and what kind of sound it can produce—by checking your vehicle model and your current system. If you’re considering replacing the rear speakers, please feel free to consult us first.
