【4.6C Coaxial 2-Way｜16.5cm Car Audio Speaker for Enjoying Natural Sound Connection】

The sound from the factory speakers comes across a little muffled, it’s hard to tell where the vocals and instruments are positioned, and when you turn up the volume you tend to get listening fatigue. If that sounds like you, you may want to consider the 4.6C Coaxial 2-Way.

A 16.5cm woofer and a 28mm silk-dome tweeter are mounted coaxially, allowing a single unit to reproduce sound from the mid-low range up to the high range. The sound connection is natural, and the finish makes it easier to perceive the expression in the vocals and the outlines of instruments. It’s well suited for anyone who wants to enjoy their everyday music in a bit more clarity and a bit more comfort.

The tweeter uses a silk dome, delivering smooth highs that won’t turn harsh. The woofer section uses a paper cone made from long-fiber pulp with special processing. Designed with a balance of light weight and rigidity, as well as internal resonance, it accurately depicts the midrange—vocals, guitar, piano, and more—while also adding an appropriate sense of thickness to the low end.

Consideration has also been given to parts that help the speaker deliver long-term, stable performance, such as an aluminum die-cast frame, a nitrile rubber surround, and a vented voice coil. It supports setups using the included dedicated high-pass filter, making it easy to expand not only to replacing speakers in a factory system, but also to building a system that combines an amplifier and DSP.

That said, with speakers, sound isn’t determined by swapping units alone. Depending on the condition of the door, the installation method, the baffle construction, surrounding vibration control, and compatibility with the factory audio, the impression can change even with the same product. If it were me, I would first check the vehicle and your current system, then organize where you need to make changes to make the best use of this speaker’s strengths and propose a plan.

Because installation dimensions, depth, and the shape of the factory speakers may vary by vehicle model, it is necessary to confirm compatibility with your vehicle before installation. Rather than deciding only the product in advance, thinking together—including the music you want to listen to, your current complaints, and your budget—leads to greater satisfaction after installation. If you’re looking for a speaker that you can truly enjoy the changes in sound with, please feel free to consult us.
