Each X-Series product has been designed to optimally perform with the others when installed together in a sound system. Key features include:

  • Speakers: The X-Series speakers combine premium materials and modern engineering to powerfully and accurately reproduce well-staged sound. Advanced technologies like the nano-fiber cone, radial ring magnet circuit, and carbon graphite tweeter allow the speakers to maintain linearity and accuracy for a realistic sound stage.
  • Subwoofers: The 12-inch X-Series subwoofer has the largest Xmax in its category resulting in huge air movement and bass output; 24mm in one direction resulting in almost 50mm of total cone travel. The motor structure and suspension are designed to support the large Xmax while maintaining accuracy and tonality. The powerful motor overcomes the massive air pressure created by small sealed enclosures, thereby allowing the subwoofers to be installed into smaller enclosures and retaining valuable space in today’s vehicles.
  • Amplifiers: The amplifiers output 20-30% more than their rated power and feature class-leading minimum phase shift and signal to noise, to deliver music like the artist intended. The thermodynamically engineered heat sink efficiently dissipates heat while the intelligent management system guarantees reliable operation. Even under the harshest conditions, the amplifier will gradually roll back power until it recovers for never shut-down performance and non-stop music.
