This woofer lets you experience the truth that changing the bass changes the music.

The 16.5cm woofer, the L-165R, is the foundation of the Bewith Reference AM series. Its high-end model combines the power and precision required for low-frequency reproduction. Each and every note contributes to the overall richness and stability of the music. The diaphragm is made of aluminum-magnesium alloy (AM), a hallmark of the series. Its lightweight, highly rigid material properties deliver fast-response, tight bass. Yet it retains a rich volume, powerfully supporting kick drums and basslines. The precisely designed magnetic circuit and highly rigid frame structure eliminate unnecessary resonance while providing superior damping. It seamlessly transitions the low-frequency response from its initial sag to its onset, creating a smooth, unified sound field across the entire frequency range. While the L-165R delivers excellent performance on its own, combining it with the Duo or Trio series fully embodies the worldview of the Reference AM.
