【165mm NPPV Cone Speaker｜A High-Quality Model for Enjoying Natural, Linear Sound】

When listening to music, do you sometimes feel that vocal voices and instrument sounds are a bit stiff? And when you turn the volume up, do you find it easier to get listening fatigue? If so, a model that focuses on the speaker materials and frame structure is a good match.

This speaker uses a 165mm NPPV cone diaphragm that inherits the tradition of the 8000 series. By coating a non-pressed pulp base with vinyl ester resin, it carefully balances the stiffness, mass, and internal damping loss levels required for the diaphragm.

As a result, the sound’s attack is less likely to be unnaturally emphasized, making it easier to reproduce vocals and instruments in a natural way. Even with music you already listen to, the nuances of the voice and the fine connections between sounds become easier to hear—an ideal speaker for enjoying music at a leisurely pace on long drives.

The frame is made of high-quality aluminum produced via CNC machining. While ensuring overall rigidity of the speaker, it is designed with a structure that effectively diffuses pressure on the rear side. In addition, the built-in ventilation structure within the motor assembly is designed to support cooling effects.

However, a speaker’s sound is not determined by the unit’s performance alone. The final impression depends on factors such as the installation condition on the door side, the rigidity of the baffle, measures against unwanted vibrations, the combination with the factory system, and even the final tuning.

If it were me, I’d decide whether to replace only the speaker itself or to also refine the door-side treatment, taking into account the vehicle and how you use it. Let’s consider together a setup that you can enjoy comfortably for a long time—by checking the vehicle model and factory audio configuration, the music you often listen to, and the direction of sound you want to achieve.
