Katabiki Driver – A New Benchmark in Planar Technology

At the core of the LUNA lies the Katabiki driver: a newly developed Unipolar Micro Planar Magnetic design, created in close collaboration with MADOO. Unlike traditional planar drivers, this unipolar design uses a powerful single magnet and a dual ring-shaped yoke for superior magnetic flux control, enabling exceptional speed, resolution, and stability.

• Ultra-thin diaphragm with printed aluminum pattern for ultra-low mass
• Aluminum CNC-milled frame for structural integrity and resonance control
• Natural tonal decay and transient realism
• Precision-engineered unipolar magnetic circuit for accurate response without distortion

Despite its single-driver architecture, the LUNA effortlessly handles complex passages across all genres—from jazz to electronic, from classical to progressive rock—rendering every note with honesty and grace.

Titanium Housing – Strength Meets Acoustic Refinement

The outer shell of the LUNA is crafted from solid titanium, selected for its exceptional strength-to-weight ratio and excellent acoustic properties. Its refined curves and metallic finish are inspired by the gentle shape of the moon—hence the name LUNA.

• Durable, lightweight, and non-resonant for optimal sonic integrity
• Sculpted for maximum wearing comfort and noise isolation
• Smooth surface finish enhances both tactile feel and long-term durability
• Designed for universal fit and fatigue-free listening

This housing isn’t just about aesthetics—every contour and material choice serves the pursuit of perfect sonic flow and user comfort.
