Folded Motion® WaveguideAfter an extensive evaluation of nearly 50 design options, the Folded Motion® Waveguide profile was meticulously chosen to harmoniously align with the dispersion of the midrange drivers, resulting in enhanced output. The waveguide guarantees consistent sound quality regardless of the listener’s position and minimises unwanted room reflections. Proper waveguide design is crucial as it helps control the sound’s dispersion pattern, ensuring that the sound is evenly distributed across the listening area and resulting in optimal sound quality. |
Nomex®-Reinforced Kevlar® Mid-Bass DriverThe Nomex®-Reinforced Kevlar® Mid-bass in the Motion® XT B100 offers a perfect balance of lightweight, strength, anti-resonance and anti-ringing properties for unparalleled sound quality. When combined with the Gen2 Obsidian FMT XT, the clarity of vocals, dialogue and instrumental accuracy is unmatched at any volume. The seamless integration with Motion® XT CI products makes creating custom solutions effortless. |
