Silk offers a smoother and more forgiving sound character, ensuring your ears don't fatigue from harshness in the high frequencies. This translates to a more pleasant listening experience, especially when enjoying intricate details in cymbals, strings, or high vocals.

 

Highlights

  • Silk dome: Compared to metal domes, silk domes offer a smoother and more forgiving sound, reducing harshness in the high frequencies.
  • XBL^2 motor technology (see below for details): This patented design by Adire Audio ensures exceptional linearity and control over the tweeter's movement, resulting in minimal distortion and clear, detailed highs.
  • High power handling: The LD25X can handle a significant amount of power without compromising sound quality, making it suitable for use in high-performance speakers.
  • Wide dispersion: The tweeter's design promotes wide dispersion of high frequencies, creating a broader sweet spot where listeners can enjoy optimal sound quality.

The LD25X is considered a comeback product by CSS, known for its impressive performance in the past. Let's explore the XBL^2 technology in more detail:

 

  • XBL^2 stands for Extreme BL Linearity. BL refers to the interaction between the magnet and the voice coil in a speaker driver. Traditional motors exhibit a non-linear BL curve, meaning the force on the voice coil weakens as it moves further from its center position. XBL^2 technology addresses this by achieving a much more linear BL curve.
  • Benefits: This linearity translates to several advantages. It reduces distortion throughout the tweeter's operating range, resulting in cleaner and more accurate high-frequency reproduction. Additionally, XBL^2 motors allow for shorter voice coils while maintaining desired force, contributing to a compact design for the LD25X.
