The New Reference in Coaxial Design

The Lii Audio H1802 is an 18-inch coaxial loudspeaker meticulously crafted for discerning audiophiles who seek both scale and coherence from a single, unified source. By integrating a wideband driver and a high-frequency unit along the same axis, the H1802 delivers exceptional time alignment and natural imaging—offering the intimacy of a full-range driver with the extension and air of a dedicated tweeter.

With 97 dB sensitivity and a frequency range from 28 Hz to 20 kHz, the H1802 captures the full emotional spectrum of music, from deep, tactile bass to refined, lifelike highs. Its 50 mm voice coil and 200 mm ceramic magnet assembly ensure precise control, dynamic headroom, and musical transparency across all playback levels.

Built to perform in open baffle, horn, or custom enclosures, the H1802 embodies Lii Audio’s philosophy—a seamless, phase-coherent sound that transcends the limitations of traditional multi-way systems.
