【Diamond 165-2｜16.5cm 2-Way Component Speakers That Bring Out Natural Sound】

You may feel that the sound of your factory speakers leaves something to be desired, but you don’t want to change the sound in a flashy way. You want to hear the finer nuances of vocals and musical instruments in a more natural way.

That’s where Diamond 165-2 comes in.

Developed as the successor model to the “RS Revelation 165-2” introduced in 2015, this 16.5cm 2-way component speaker is built on the philosophy inherited from its predecessor—“minimize coloration and reproduce the sound as it truly is.” By rethinking the parts and overall structure, it enhances both resolution and expressive power.

The 26mm silk dome tweeter uses a neo­dymium magnet. While delivering detailed high-frequency information, it is less likely to sound piercing or harsh, letting you hear vocals’ breath-like nuances and the subtleties of string instruments naturally.

For the woofer, it combines a 32mm voice coil with a large ferrite magnet and adopts a newly designed basket made from aluminum die-cast. While adding thickness to the midrange, it also firmly supports the low frequencies. Even with songs that have many musical elements, each part is less likely to get buried—this is a speaker that makes you want to listen to your favorite tracks all over again.

Your final result changes with installation and adjustment

Speakers don’t produce their true sound just by choosing the product. Depending on the condition of the door, the installation method, how it’s combined with your factory audio system, and the tweeter’s orientation, the impression can vary even with the same speakers.

To take advantage of the natural sound of the Diamond 165-2, proper installation matched to your vehicle and careful adjustment that considers how sound connects from front to rear are important. Whether you’re planning to replace your factory speakers or you want to refine the sound while keeping your current system, we’ll determine the direction together based on your vehicle model, how you use it, and the music you listen to most.

Sound preferences differ from person to person. If I were choosing, I wouldn’t base it only on a speaker’s specs—I’d confirm what kind of sound you actually want to hear, and then make the selection. For those who want natural sound that’s easy on the ears, this is a model well worth considering in depth.
